ThunderPower’s Top 3 First Responder Megaphones

A first responder megaphone, a THUN-250, is propped on the front bumper of a fire engine, along with a safety vest and a firefighter helmet.

When disaster strikes, first responders need the best communications equipment available for coordinating relief efforts and getting people to safety. That includes the use of powerful megaphones and bullhorns. ThunderPower is proud to support medical personnel, law enforcement, and firefighters with our full lineup of high-quality products. Here are the first responder megaphones we think are the best options on the market.

Recommended Megaphones

The THUN-250

We like to say this megaphone is the perfect balance of power, size, and weight. Why? Comparable models from our competitors are often bigger and more expensive, whereas we keep ours light, user friendly, and cost effective. The THUN-250 offers a range of up to 1,200 yards, backed by 25 watts of power.

The THUN-450

For emergency responders who anticipate needing megaphones for an extended period of time, the THUN-450 is the perfect choice. It boasts a range of 1,400 yards with 35 watts of power, and comes with a shoulder strap and detachable palm mic for easy handling.

The THUN-1200

Otherwise known as “The Earthquake Maker,” this is ThunderPower’s loudest megaphone. Rocking 45 watts of power and voice projection up to 2,000 yards, this heavy-duty model was designed for crowd control and military applications. It comes with an auxiliary sound jack, as well as a cigarette plug that allows it to run off of vehicle power (batteries are still an option).

Why First Responder Megaphones Are Essential

Although there have been several advancements with emergency communication over the years (two-way radios, for one), there are still plenty of example scenarios where first responder megaphones are the superior option. Case in point: say that law enforcement has a large crowd of people who all need to receive the same instructions to perform at the same time. Megaphones allow them to do this instantaneously, and in such a way that people can organize and move in a coordinated effort that minimizes risk.

These megaphones are also ideal for first responders because they’re made with high-grade industrial plastic. This means they can handle more than their fair share of wear and tear from regular use, continuous movement, drops, and other typical on-the-job hazards. 

Instantly projecting one’s voice to a crowd as close as a few feet or as far away as 2,000 yards can be advantageous for first responders. Responders can give directions to people they can see, as well as get the attention of those they can’t but who still need their help. 

Megaphones also work the other way around, allowing civilians to call for help and get the attention of first responders who may not realize that they’re present. That’s why we often encourage customers to add them to their disaster kits.

Honorable Mention: Disaster Kits

ThunderPower megaphones offer exceptional range and voice clarity. They’re easy to store and only require a handful of batteries. These reasons make them simple and effective additions to any disaster kit. Other forms of communication like mobile phones can fail, either when cellular networks are overwhelmed or the internet goes down, but people can still rely on megaphones to be heard.

Although a bullhorn may not be the first item that comes to mind in an emergency, it’s certainly one of the most reliable.

ThunderPower Spotlight: The THUN-120 Megaphone

A THUN-120 megaphone is displayed beside the text, "15 Watts. 800-Yards Range."

When customers tell us that they’re looking for the best-quality megaphone at the most affordable price, the THUN-120 megaphone immediately springs to mind. This week, we spotlight the benefits of this lightweight, reliable bullhorn that we so often see used for parades, coaching, school pickup and drop-off lots, campus crowd control, theater productions, and outside events like fairs and farmers’ markets.

Sound and Range

All ThunderPower megaphones offer clear, exceptional sound quality, and this model is no different. At 15 watts of power and 800 yards of range, the THUN-120 can amplify your voice just shy of 7.5 NFL-sized football fields!


The THUN-120’s lightweight design is complemented by an ergonomic pistol grip and attached wrist strap. Handling is intuitive, thanks to a convenient three-way switch for choosing between voice, siren, and whistle, as well as an adjustment wheel to select the appropriate volume.


Industrial-grade plastic is what allows the THUN-120 megaphone to be lightweight, but don’t think that that means it’s fragile. It’s built to withstand plenty of use and bumps along the way — especially if you’re protesting! Those wrist straps we mentioned earlier are also great for preventing drops, loss, and theft.


It only takes eight AA batteries to experience 15 watts of power! Swapping out dead batteries is also quick and easy. Just make sure to follow our tips on how to use a megaphone properly — i.e., always speak directly into the microphone, don’t speak softly, and only adjust the megaphone’s volume instead of your voice!


The THUN-120 offers a 10-inch-diameter bell and extra-loud, solid-state speaker so that it can be used in a variety of settings, both indoors and out. This not only makes it flexible in terms of use, but also means you don’t have to break the bank by purchasing a ton of units just for a single event.


We make it a point that all ThunderPower models come with a “full 1 year, expedited in-house express warranty.” We stand by our products, and we want you to have complete peace of mind that you’ll get the maximum use out of every megaphone you purchase.

Why Choose The THUN-120 Megaphone — Or ANY ThunderPower Model

There are several options out there when it comes to selecting bullhorns. There are three reasons we think you should choose ours — whether it’s the THUN-120 or the other exceptional megaphones in our lineup:

  1. We offer world-class quality at the best available prices. (As of this post, our megaphones are even more cost-effective because they’re on sale!)
  2. We’ll answer your call the moment you dial. We don’t like making people navigate convoluted phone trees or getting stuck playing phone tag.
  3. Our orders can often ship as soon as the day they’re placed.

    You may be wondering why we say “megaphone” and “bullhorn.” Is there a difference? While the products we sell are technically bullhorns, both terms have become synonymous. Rest assured that we’re always referring to battery-powered models. If you’re interested, you can learn more about the evolution of their names here!

    Do you have questions about the models that we offer, or about megaphones in general? We want to hear them!

    Coaches, Use These Sports Megaphones To Prevent Vocal Strain

    A coach stands on the sidelines beside a blown-up image of a THUN-120 megaphone. Text reads, "Coaches, Save Your Voice. Use a Megaphone."

    School’s back in session, and sports teams are gearing up for a new season! That means plenty of coaches across the country should be mindful of one thing: not losing their voice. If you’re a coach, we recognize how hard you must work to teach and mentor your players during practice and live events. But that shouldn’t come at the cost of your vocal chords and general health. While we strongly believe that sports megaphones are key to avoiding undue strain on your speech, we acknowledge that this isn’t the only solution you may need.


    Megaphones fall under the category of noisemaker, which is usually banned from use during live game play. This means that while we can obviously share the benefits of using them during outdoor events and team practices, you’ll still need a plan for what to do when they aren’t an option.

    We address some of those through the questions below.

    Why Are Coaches’ Voices at Risk?

    Hopefully you’re fortunate enough not to have experienced throat pain from yelling too much. Or, if you have, maybe you were wise enough to give your vocal chords time to heal before risking more damage. Either way, the reality is that vocal strain can affect coaches to different degrees depending on the sport, where it’s held, and how many people you’re trying to talk over. 

    Basketball coaches arguably have it the worst. They’re indoors, in rooms that can get exceptionally loud, and unable to use sports megaphones during live games. But because they need to communicate with their team, and because “the pressure to perform often leads coaches to yell,” The New York Times notes how there’s “rarely a moment during a game when a coach can use a normal conversational voice.” 

    Just how bad can vocal damage get?

    Turns out, a lot. One coach even had to go in for two surgeries to remove polyps that formed in his throat.

    Are There Home Remedies?

    That same NYT article notes how many coaches who have accepted throat pain as part of their profession also rely on home remedies for treatment. These range from “daily cups of tea,” to “salt water in the morning and before games,” to Life Savers and cough drops. 

    Some say they simply get used to straining their voices, although that’s not recommended.

    What Other Options Do Coaches Have?

    Besides home remedies, coaches can try to prevent throat pain from happening in the first place through the use of vocal training. Similar to how singers practice ways to protect their vocal chords, coaches can adapt by learning safer voice projection techniques.

    Another means of curbing undue vocal strain is to measure how much coaches are using their voices. Researchers are looking at how to identify vocal fatigue through the use of a “soft, flexible, postage-stamp-sized device [that] comfortably adheres to the upper chest to sense the subtle vibrations associated with talking and singing.” That data is then shared with a smart device to “monitor their vocal activities in real time throughout the day and measure cumulative total vocal usage.”

    Can Technology Help?

    When it comes to live games, it looks like coaches need to be mindful of how they yell, how often they yell, and what vocal training or home remedies they prefer to soothe any discomfort. As for practice, that’s where technology can give them the upper hand.

    While some coaches have been known to use microphones connected with wireless PA systems, you shouldn’t be surprised to hear that our main recommendation is to use powerful sports megaphones.

    What Sports Megaphones Does ThunderPower Offer?

    ThunderPower maintains several megaphone models that coaches can use to train their teams. They include:


    Power: 15 watts.
    Range: up to 600 yards.
    Voice amplification: up to 98 decibels (dB), with siren up to 112 dB.
    Number of batteries: eight (8) AAs.

    The THUN-150 may be the smallest of ThunderPower’s sports megaphones, but it still packs a punch! It offers clear voice projection, options for a siren and whistle, a lapel microphone, adjustable volume control, and a convenient wrist strap.


    Power: 15 watts.
    Range: up to 800 yards.
    Voice amplification: up to 100 dB, with siren up to 112 dB.
    Number of batteries: eight (8) AAs.

    Shaped more like traditional sports megaphones, the THUN-120 offers a compact, lightweight design that’s reinforced by an industrial-strength chassis. Similar to the 120, it comes with a nylon carrying strap. 


    Power: 25 watts.
    Range: up to 1200 yards.
    Voice amplification: up to 102 dB, with siren up to 118 dB.
    Number of batteries: six (6) Cs.

    This is one of the best medium-sized, long-range megaphones on the market, offering the same features as the previous models but with greater range and power.


    Power: 35 watts.
    Range: up to 1400 yards.
    Voice amplification: up to 108 dB, with siren up to 120 dB.
    Number of batteries: eight (8) Cs.

    The THUN-450 is incredibly loud, and offers a detachable palm mic for added convenience.

    Please note: batteries not included with these models, but we do sell them.

    ThunderPower Spotlight: The THUN-150 Megaphone

    A THUN-150 megaphone and lapel mic are displayed next to a school administrator using this megaphone in the hallway around students. A tagline reads,

    Even if a megaphone is small, that doesn’t mean it can’t pack a punch. Case in point: the THUN-150. As the most compact member of the ThunderPower lineup, it’s often used by educational staff, parade operators, day care workers, tour group leaders, coaches, and event planners. Learn more about why we call the THUN-150 megaphone “real power in a tiny package,” as well as helpful tips and specials that are currently available for this model.

    Sound and Range

    All ThunderPower megaphones offer exceptional sound quality and clarity, and that includes the THUN-150. Your voice will easily be heard up to 600 yards away, and you can utilize a siren or whistle when you really need to get people’s immediate attention. An audio input is also available for connecting a lapel mic or other audio devices.


    Its compact size (weighing slightly over 2 pounds) and ergonomic pistol grip both make the THUN-150 a cinch to carry and operate. Volume control and audio selection for voice, siren, and whistle are all conveniently placed above the grip so that you can quickly adjust them with your thumb. 


    Made with industrial-grade plastic, this megaphone is designed to take more than its fair share of bumps and scratches that are expected from repeat use. Plus, all 150s come with reinforced-nylon, web-wrist lanyards to prevent drops and loss.


    The THUN-150 boasts 15 watts of power and only requires 8 AA batteries for long-lasting service. When it’s finally time to swap those batteries out for replacements, this megaphone’s design makes it fast and convenient to do so — no complicated searches or tricks to open the battery compartment required. (Consider purchasing rechargeable batteries to save on replacement costs.)


    Its five-inch-diameter bell and eight-inch chassis offer 90-degree sound projection that lends itself well for indoor and outdoor situations.


    All 150s come with a “full 1 year, expedited in-house express warranty” for your complete peace of mind.

    Now that we’ve covered the benefits of the THUN-150 megaphone, let’s discuss some tips you can apply when using it.

    Tip #1: Flip Your Batteries

    We already highlighted rechargeable batteries as a way to save money while keeping your megaphone powered. You might also consider flipping your batteries in their slots when you put your megaphone into storage. This prevents the possibility of it being activated while you’re away, which would needlessly drain its batteries.

    Tip #2: Add the THUN-150 to Your Disaster Kit

    People often think about including flashlights and radios in their disaster kits, but they may not realize just how beneficial megaphones can be. This is especially true for the THUN-150. Thanks to its smaller size and portability, it can be easily stored for emergency use and provide long-lasting power until help arrives.

    Tip #3: Speak Loudly and Directly Into the Microphone

    If you think your megaphone is too loud, don’t worry about adjusting your voice by speaking softer or by holding the megaphone farther away from you. Always speak directly into the microphone and always speak loudly — adjusting the volume on the model itself will handle the rest.

    Current THUN-150 Megaphone Specials

    As of this blog post, we’re offering a couple special offers for our THUN-150 megaphones.

    1. Units are currently on sale at 10 percent off normal retail price.
    2. You can get a free THUN-150 when you purchase six (6) or more industrial radios from our friends over at Discount Two-Way Radio!

    ThunderPower Offers Superior Megaphones for Cheerleaders

    Cheerleaders, football players, and a coach all huddle together with a trophy to celebrate a winning game. A cheerleader holds a ThunderPower megaphone.

    Cheerleading season may be coming to a close, but that doesn’t mean squads won’t be practicing over the spring and summer, and they’ll need megaphones! ThunderPower is here to help teams ensure their routines go smoothly and their voices are heard so that they’re ready to crush it at their next major competition or sporting event. Learn how, and which megaphones for cheerleaders we recommend.

    The History of Megaphones for Cheerleaders

    Megaphones have been a part of cheerleading since they were wooden and acoustic. In fact, their first recorded use with a cheer team dates back to 1898 at the University of Michigan.

    These days, ThunderPower’s electronic models — also known as bullhorns — are made with industrial-grade, molded plastic, making them preferable because of their added strength, enhanced clarity, and extended range. We carry several bullhorn models to meet the specific needs of your training.

    Megaphone Pro Tip

    If you really want some force behind your cheers, make sure to take a look at “The Earthquake Maker,” our most powerful megaphone. Running on 45 watts and offering a range of 2000 yards, the THUN-1200 is guaranteed to make you the loudest person at any event. Plus, it’s big enough to require a carrying strap and speaker mic for ease of use.

    ESSER II and ARP ESSER Funds

    Not sure if you have the money to budget for new megaphones? Check if your school has funds remaining from ESSER II and ARP ESSER. If you’re not aware, these packages were part of COVID relief authorized by the federal government for schools to make improvements to air quality, cleaning and sanitation, and communications equipment. It’s worth confirming with your district if megaphones apply, and that you make sure to obligate available funds by their respective deadlines (September 30th of this year for ESSER II, and September 30th of next year for ARP ESSER).

    Cheerleader Safety

    Safety’s a big part of any sport, and cheerleading is no exception. Summer practice can be more difficult due to the heat, which is why TheCheerBuzz offers some tips on how to protect your squad members.

    Megaphones also contribute to that safety. If one of your team members feels threatened, they can use a megaphone to call for help, or activate its siren to alert others. (This is why we highly recommend that everyone has a megaphone in their disaster kit.)

    ThunderPower Megaphone Suggestions

    While we stand by the quality and craftsmanship of all of our models, here are the megaphones for cheerleaders we recommend when you’re looking for new ones for your squad.

    THUN-150: 15 watts, 600-yard range, 98 decibels (dB) for voice, and 112 dB for siren.

    THUN-120: 15 watts, 800-yard range, 100 dB for voice, and 112 dB for siren.

    THUN-250: 25 watts, 1200-yard range, 102 dB for voice, and 118 dB for siren.

    6 Essential Battery-Powered Megaphone Tips To Make Sure Your Voice Is Heard

    A battery-powered megaphone, the THUN-450, has its major components labelled.

    Whether you’re participating in a rally, coordinating an outdoor event, instructing students in an auditorium, or guiding players through drills on the practice field, megaphones and bullhorns are the best tools for getting your voice heard. To use yours effectively, make sure to review the following battery-powered megaphone tips — then let us know if you have any questions about the models we currently have available.

    1. Speak Directly Into the Megaphone

    Depending on the type of megaphone that you purchase, its microphone will either be built into the back of the unit or connected to it as an attachment. Operate both the same way by talking directly into their microphones — i.e., hold them as close to you as possible

    Megaphones may be excellent at projecting sound, but those sound waves have to reach them first. More of them will when you limit the space between your mouth and the microphone. 

    We’ve seen users who thought they could get away with holding their bullhorns at arms’ length, then learned very quickly how no one could hear what they were saying.

    For an easy comparison, treat your megaphones like musical instruments.

    2. Speak Loudly

    Don’t lower your voice when you use a megaphone. Whispers or mumbling won’t be any better when they’re magnified, which means you need to talk with power and confidence to get the farthest, cleanest results. 

    Let’s take it right back to that music analogy: the more sound you put in, the greater it projects.

    Worried you’ll be too loud? Adjust the megaphone’s settings, not your voice.

    3. Flip Your Batteries When Storing Your Megaphones

    One trick that you might find handy for conserving the lifespans of your megaphone batteries is to flip them backwards in a unit prior to storage. This avoids the possibility of the unit being unknowingly activated if anything were to be placed on top or beside it that might press its talk trigger and drain the rest of its power. Just remember to leave yourself a note when it’s time to pull your bullhorn back out so that you or your coworkers don’t mistakenly think its batteries are already dead.

    This tip helps avoid accidental alarm activation, too. And speaking of alarms…

    4. Be Careful Which Buttons You Push

    Not all megaphones are made the same, which is why ThunderPower designs theirs to be intuitive and user friendly. That said, it’s still a good idea to review all of the available functions and where they’re located, just so you don’t choose one that causes unnecessary commotion — like the megaphone’s siren.

    Depending on the model, the siren may be activated with a switch beside the microphone, a toggle at the base of the pistol grip, or a button on the top handle. Always verify that yours is in the correct position before use.

    5. Purchase Rechargeable Batteries

    ThunderPower megaphones offer exceptional range and sound quality, which can require several AA or C batteries based on the model. Depending on how often you use these megaphones, you may find it more cost effective to purchase rechargeable batteries.

    6. Consider Megaphones With Shoulder Straps

    If you need bullhorns with a lot of power, but also plan to be on the move, you’d do well to look for units that come with shoulder straps. They make transporting these megaphones easier, and reduce the chances of having them misplaced or damaged. Plus, ThunderPower’s larger units also include palm mics, which allow you to continue using them while they’re still being carried.

    Which Megaphones Do You Need?

    If you’re looking to purchase new megaphones, here’s a breakdown of the units we currently offer, with links to each.

    THUN-150: 15 watts of power and a 600-yard range, with voice amplification up to 98 decibels (dB) and siren at 112 dB. 

    Recommended for: teachers, parade operators, event organizers, and tour groups.

    THUN-120: 15 watts of power and an 800-yard range, with voice amplification up to 100 dB and siren at 112 dB. 

    Recommended for: coaching, theater productions, school pickup and drop-off lots, as well as campus crowd control.

    THUN-250: 25 watts of power and a 1200-yard range, with voice amplification up to 102 dB and siren at 118 dB. 

    Recommended for: law enforcement, first responders, teachers, and coaches.

    THUN-450: 35 watts of power and a 1400-yard range, with voice amplification up to 108 dB and siren at 120 dB. 

    Recommended for: political rallies, outdoor festivals, and religious congregations.

    THUN-1200: 45 watts of power and a 2000-yard range, with voice amplification up to 112 dB and siren at 122 dB. 

    Recommended for: military training, firefighters, security, and massive gatherings.

    The Best Bullhorn Used To Manage Crowds

    A THUN-1200 bullhorn used to manage crowds at an outdoor fair is currently resting on a field beside vendor tents.

    Are you getting ready for your next big outdoor event? While there are plenty of factors to prioritize — from sanitation and pest control, to permits, power, and cleanup — the one area you can’t afford to go without is communication. Make sure that you have all of the equipment necessary for keeping your event organized, efficient — and, most importantly, safe. If you’re anticipating a lot of people, here are our suggestions on the communication areas you’ll need to focus on, as well as the best bullhorn used to manage crowds.


    If your event runs after sunset, do you have the proper lighting planned? This isn’t just for your vendors and performers — we’re also referring to lights that will help your customers know where to park, find their way around your venue, and know where to go in the event of an emergency. And, if the weather ever becomes too troublesome, that lighting could also come in handy with the next item on our list.

    Directing Traffic to a Backup Location

    Having a secondary location in mind for your event is ideal if you’re anticipating any last-minute changes. Weather is certainly a big one, but it’s possible that other unforeseen circumstances would warrant a new venue. Regardless of the reason, you’ll want to make sure that the majority of your equipment is easy to transport and reassemble at your backup site. The lighting we mentioned above could be part of those efforts if the secondary location is within walking distance, or to identify it for others when arriving by car. 

    Coordinating these efforts also means advanced prep work, as well as the best bullhorns to relay instructions if and when the time comes.

    Bullhorns (or Megaphones)

    Whether you call them bullhorns or megaphones, these are the best tools for interacting with — and directing — large groups of people. Vendors can use them to get more people to come to their tents or displays, parking attendants can use them to direct traffic, and stage performers can use them to get your crowd energized. They’re also ideal for communicating group instructions to event team members while they’re breaking down and transporting equipment, responding to emergencies, or getting attendees to listen to important announcements. 

    In our experience, the best bullhorn to manage crowds is the THUN-1200. Referred to as “The Earthquake Maker,” it offers 45 watts of power and a range of up to 2000 yards! 

    How loud is that, exactly? We’re talking the same level as a rock concert or a thunder clap. In other words, you will be the loudest voice at your event. 

    To stay portable in spite of its size, the THUN-1200 comes with a carrying strap and a palm mic. It’s also designed with heavy-duty, industrial-grade plastic to protect it from normal wear and tear, including potential drops that may happen along the way.

    Does the THUN-1200 sound like too much megaphone for your event? We offer other models with reduced ranges to fit any venue, crowd size, or personal preference. Check out our full lineup, all of which are on sale as of this post!

    Honorable Mention: Industrial Two-Way Radios

    Looking for a less conspicuous way to coordinate a crowd? Don’t forget about industrial two-way radios. These are designed to make every aspect of your event appear effortless, thanks to uninterrupted, dependable, crystal-clear communication. You can also pair them with earpieces and speaker mics to give your users a more hands-free experience while they work.

    Head over to our friends at Discount Two-Way Radio for more information about the best models that will fit your needs and budget.

    Ready To Choose Your Next Bullhorn?

    While we think the best bullhorn used to manage crowds is the THUN-1200, don’t be discouraged from comparing all of ThunderPower’s phenomenal models. It really comes down to crowd size, venue location, and what you’ve got planned that will determine the best bullhorn for your needs.

    While you can certainly compare the specs for these models on our website, why not make that process easier and talk directly with one of our megaphone specialists? Give us a call at 877-782-7073 when you’re ready to learn more.

    Bullhorns and Megaphones: What’s the Difference?

    Megaphones and bullhorns concept. A vintage, wooden megaphone is compared to a current-day bullhorn, with the tagline,

    Maybe you’ve already been using bullhorns and megaphones for a while, or perhaps this is the first time you’re looking to purchase. Either way, you may have wondered: is there a difference between the two? And does that mean you’ve been looking at the wrong products? Learn more about what each term really means, its history, and the models that we recommend.

    Is There Really a Difference?

    Technically, yes. 

    Megaphones came first. These are defined as horn- or cone-shaped tubes that make sound audible over greater-than-normal distances. Bullhorns are actually a type of megaphone, but are defined as those that project sound electronically

    It’s that simple.

    That being said, most people use these terms interchangeably today, to the point that distinguishing them isn’t so important when you decide to go shopping. You can use either term and still find the products you’re looking for, without having to worry about ending up with a simple plastic tube you could have easily fashioned yourself. Not that there’s anything wrong with traditional megaphones — they share a long history with the Olympics and cheerleading, after all.

    How Long Have Bullhorns and Megaphones Been Around?

    You might think the 1908 Olympics were a long time ago, but megaphones have arguably been in use for far longer. According to Acoustical Engineer, Native Americans and the ancient Greeks both used versions of “speaking horns” to communicate with large crowds and during theater performances, respectively.

    By comparison, bullhorns are still babies, having only been around since the 1950s after the development of microelectronics.

    How Do Bullhorns and Megaphones Work?

    Bullhorns and megaphones depend on the concepts of directivity and acoustic impedance. Again, Acoustical Engineer offers the best summary of each: directivity measures “how much sound energy goes in what direction,” while acoustic impedance measures the amount of resistance that sound encounters as it crosses different forms of matter. For example, when you speak, the sound from your vocal cords encounters acoustic impedance from the air as it leaves your mouth — so much so that some of that sound is even reflected backwards.

    Megaphones ease this transition so that more sound is able to pass from you into the air, allowing it to be audible farther away.

    Bullhorns operate on the same principles, but offer expanded range thanks to electronic components like microphones and amplified speakers. Most bullhorns are handheld units, although some get large enough that they require these components to be separated. The THUN-1200, for example, is designed to be carried with a shoulder strap, while allowing users to communicate through a corded microphone similar to those you see on mobile two-way radios.

    What Are the Best Options?

    Below, you’ll find a full breakdown of each of the bullhorns that ThunderPower currently offers, including their ranges and the industries or activities that benefit from them the most. As of this blog post, all of our units are also on sale!

    THUN-150. Operating at 15 watts, this bullhorn can project sound up to 600 yards. It requires eight (8) AA batteries, and is ideal for teachers, parade operators, event organizers, tour groups, sporting events, and cheerleading.

    THUN-120. Similar to the THUN-150, this unit also operates at 15 watts and takes eight (8) AAs, but increases its maximum range to 800 yards. This comes in handy for coaching and cheerleading, as well as theater productions, school and university crowd control, parades, fairs, and farmers’ markets.

    THUN-250. This bullhorn offers 25 watts of power, reaches up to 1200 yards, and requires six (6) C batteries. It’s designed to work best for teachers, coaches, demonstrators, law enforcement, and preachers.

    THUN-450. Eight (8) C batteries gives this model 35 watts of power and a range of up to 1400 yards, which is perfect for political rallies, outdoor festivals, religious congregations, and sporting events.

    THUN-1200. Commonly referred to as “The Earthquake Maker,” this is the loudest and biggest bullhorn we carry. It packs a punch at 45 watts, giving you a range of up to 2000 yards, and only requires eight (8) C batteries. This model is ideal for military training, law enforcement, firefighters, security professionals, and mass gatherings.

    4 Activities You Forgot Actually Depend on Rechargeable Megaphones

    A target board from the Winter Olympics rests in the snow beside a ski flag and a ThunderPower megaphone.

    You may have seen our earlier discussion about why fall is a great time of year to purchase new megaphones, and some of the venues where they’re particularly helpful. We’ve talked about protests and sporting events, music venues and festivals. We’ve even shown how important these models can be as part of a disaster kit. But the reality is that rechargeable megaphones are important to have at any point in the year — either for activities you perform, or the ones you watch for entertainment.

    What exactly do we mean by that? 

    Check out our list of the four activities you may have forgotten actually depend on these megaphones.


    Whether you already live by a body of water, or you’re traveling to one around the holidays, there are plenty of opportunities to enjoy time out on it (even if it’s too cold to swim). Boating has been a popular pastime as far back as the 1600s, notes Fast forward to today, and it’s only become more widespread, thanks to better technology and affordability. Plus, the COVID-19 pandemic prompted more people to look for outdoor activities, making this a logical solution.

    That said, all activities carry some degree of risk. What better way to alert your fellow boaters and those along the shore that you’re experiencing an emergency than the crystal-clear audio from a ThunderPower megaphone?

    The Olympics

    We’ve talked before about how beneficial megaphones are for sporting events, and the Olympics — showcasing the prowess of the best of the best — is clearly no exception. When in doubt, check out these black-and-white images shared by NPR from the Games held in London back in 1908. If you scroll through, you’ll catch a shot of the master of ceremonies with an acoustic model, followed shortly by another man holding one as he assists an ailing runner at the end of a race.

    The only difference between then and now is the use of rechargeable megaphones. We know because ThunderPower has had the honor of filling that need — specifically, at the Winter Games in Vancouver.


    After covering recreational boating and sports, it only makes sense that rechargeable megaphones would also work well when these activities are combined. Right before the pandemic, we had the opportunity to supply a youth rowing club with ThunderPower megaphones and RCA two-way radios. Their trainers loved how our equipment made it effortless for them to communicate key instructions with their teams on how to maintain precise formation, coordination, and power. Choosing long-life, lithium-battery-operated units like ours allowed these trainers to stay in contact with each other and their students at all times.

    Note: Rowing teams aren’t the only groups to benefit from combining megaphones and two-way radios. Schools across the US have done the same. In our experience, RCA industrial radios are the best options for improving communication networks and student safety.

    Film Production

    The idea of megaphones being used for film and television probably conjures up images of directors sitting in tall, wooden chairs, shouting stage instructions right before clapperboards snap and cameras roll.

    As for today? While a lot of films may go the CGI route, either to fill in large crowds or add in multiple layers to a single frame, there are still plenty of directors who choose authentic, on-location shoots. These can sometimes be in large areas and require coordinating an army of extras, all of which depends on durable, high-powered megaphones.

    Conversely, we’ve also seen how smaller sets can use them to their advantage. We’ve highlighted before how our megaphones ended up on Kirstie Alley’s reality TV series, as well as Gordon Ramsey’s “Hell’s Kitchen.”

    How To Choose the Right Rechargeable Megaphone

    The bottom line: megaphones are still used for many of the same reasons they once were, and they’ve only gotten better with age. Now they’re able to reach greater distances, offer better sound clarity, and withstand more on-the-job wear and tear. But it’s worth noting that this kind of consistent, reliable performance all depends on ample battery power. Below you’ll find a full list of our megaphone models, how many batteries each one requires, as well as their ranges and decibel (dB) levels. Clicking the link to each will give you further information about that unit, including key features like adjustable volume and pistol grip, along with the sound of its siren alarm.

    Why a Megaphone Is Essential to Your Disaster Kit

    A THUN-1200 megaphone is set beside a first aid kit as part of a disaster kit.

    You don’t have to be a doomsday prepper to understand the value of a good disaster kit. Whether you’re in an area that’s prone to dangerous weather, fires, or other extreme acts of nature, you may already have one assembled. Even if you don’t, read on to learn why we think you should add a megaphone to that survival kit, and which models are ideal. First, let’s do a quick review of the other items you’ll want to make sure to include.

    Don’t Forget the Basics

    All disaster kits should contain plenty of water (one gallon per person per day) and food (several days’ worth of nonperishables), according to As for other essentials, FEMA has you covered. Their outline for a basic disaster kit includes flashlights, batteries, first aid, dust masks, plastic sheeting, wrenches and pliers, a manual can opener, and local maps. 

    So what about communication? It probably won’t come as a surprise that recommends having a cellphone, preferably with a backup battery. The same goes for a whistle that you can use to signal for help. In our opinion, though, a megaphone would be more reliable than both of these combined. 

    Here’s why.

    1. Cellphones Can Be Unreliable

    Whether we’re talking about older “brick” phones, or the latest smart devices, mobile phones aren’t the most reliable options in an extreme emergency. Cell towers can get overwhelmed when too many users try to connect, which can end up dropping or denying a lot of calls. Plus, if the disaster damages that tower, you’ll be left without any reception.

    2. Whistles Are Loud, but Megaphones Are Versatile

    We’d like to clarify that we aren’t discouraging you from using whistles. You may already own one that easily competes with the decibel level and range of a megaphone. But whistles only make one sound, and megaphones can carry your voice, so you be the judge of which one is more versatile when you need to get people’s attention for help.

    Honorable Mention: Handheld Two-Way Radios

    FEMA also mentions having either a battery-powered or hand crank radio. Our friends over at Discount Two-Way Radio would certainly agree. If you want the most durable, cost-effective models on the market, make sure to ask them about RCA.

    Which Megaphones Are Ideal

    If you’re looking for the best megaphones for your emergency kit, you want models that are easy to carry, and that offer the farthest range, clearest sound quality, and longest battery life. Our top two recommendations are the THUN-450 and THUN-1200.

    Operating at 35 watts of power and effective up to 1400 yards, THUN-450s offer voice amplification up to 108 decibels (dB) and sirens at 120 dB. They’re normally recommended for political rallies, outdoor festivals, and religious congregations.

    Rocking 45 watts of power and effective up to 2000 yards, THUN-1200s (AKA “Earthquake Makers”) easily reach 112 dB for voice and 122 dB for sirens. They’re normally recommended for military training, firefighters, security, and massive gatherings.

    Business, or Personal Use?

    We suggest the loudest megaphones because we assume you’ll want to be heard as far away as possible, but there are also less powerful options that are just as durable and reliable, depending on the needs of your situation. Whether you’re ordering these models on behalf of a business or for personal use, all ThunderPower megaphones guarantee that your voice will be heard. And, if you’re part of an on-the-ground relief effort instead of those seeking aid, we have options that are ideal for coordinating emergency response.

    Are You Prepared?

    Don’t risk being caught unprepared without a proper disaster kit. As the saying goes, it’s better to have it and not need it, than need it and not have it. Take a look at some of the megaphone models that are currently in stock and available to ship as soon as today, then let us know if you have any questions.
