ThunderPower 45 W Extra‑Loud Heavy-Duty Megaphone – 2,000‑Yard Range, 12″ Bell, Siren & Talk Modes, Aux-Input, DC Charger, for Military, Crowd Control, First Responders, Protestors (THUN1200)

Very loud. Love it. Will put one on each of my ebikes.

Wear Ear Plugs... WOW!! This Is Loud!! (12 Volt car plug adapter uses 3 amp fuses,comes with only 1-auto parts has them) If There Is Another Megaphone That Is Louder I Do Not Understand Why You Would Need It. This Wakes Up The Neighborhood, Scares People, It Definitely Gets Attention!! I Use It To Get Neighbors To Turn There Stereos Down - Put There Fires Out, I Can Also Plug My Guitar & Play... It Also Comes With Mini Jack Adapter Plug For Smaller Line Jack Sources. I Use My Android To Play Music With It. I Plug My Weather Band Radio Into It, I Did Not Let The Negative Feedback Steer Me Away, There Are Way More Positive. I Am Happy I Have This THUNDERPOWER 1200 I Plan On Using It To Deter Black Bear In The Forest If They Get To Close. I Will Be Showing It Off Plugged Into My 12 Volt Plug On My Grizzly ATV During The 4th of July Parade. HAVE FUN!!!

I guess that it's loud, but there's no effective volume control. It's a failure in many other ways, too.There are two separate volume controls. If you are speaking directly into the megaphone, there is a blue volume control knob that you can use to turn the sound up or down or to turn the megaphone off. However, if you use the handheld mic, it has its own volume, independent of the blue volume control, and it can't be turned up, down, or off; if you bump the mic button, the megaphone is on whether you've turned it off or not. You literally cannot turn the megaphone off. You can turn off the blue button and hope that nothing taps the handheld mic.The siren button is next to the volume button and it's extremely delicate. It's almost impossible *not* to be activating the siren continually if you're moving around at all.The aux input requires that you hold the aux cable into position, hard, continually. You cannot move if you want to use the aux input. This means that you effectively cannot, for instance, play music through the megaphone.My first time out with it, the hinges broke. The back of the megaphone is a door that you open to put the batteries in. (This is a ten-minute task, because the slots for the batteries are way too lose, so they're constantly falling sideways and in each other's way. You can't just drop them in. You drop one in, go after it with a knife to pry it into place, drop another one in, which falls out of place, and when you pry it into place, the first one has slipped back out of place, and so forth. You have to do this for each of eight batteries, and for some of them, more than once.) The door just fell directly off; the hinges that were to hold it on lost their pin when I first tried to carry it somewhere.It's possible that I just got the one with a failed aux input and a failed battery door. But the mic volume issue, the siren issue, and the badly-arranged battery compartment issue are inherent to the design. If you want a badly-designed siren, you can get one for less than $200; if you want something other than a siren, you should get something different from this.

This thing is crazy loud.. I gave it all 5 stars but I do have a few complaintsIt NEVER turns off.. the volume knob clicks off.. but the megaphone still works. maybe mine is defective. IDK. I just take out the batteries when it's not in useAlso the siren is really easy to hit on accident.The battery "door" backend. whatever its called, came off. the pin must have come out of the hinge. I used a heavy duty paperclip to put it back together.It doesn't really deserve 5 stars. I'm just glad that I got it and its loud.

I bought one of these brand new awhile back from this seller. The siren volume dial never changes volume level, it is just loud, great for scaring off approaching bear, threatening animals, etc... The mic volume works with static as you change it or move the mic button while talking and please be careful of feedback, woah... be careful. I hooked my cell phone up to the microphone auxiliary jack and it plays music very loud without static, I also chained speakers together with wire jacks plugged into speaker mic outlets for a chain stereo sound reaction, this is very cool with not much base, but high quality long distance sound, I could see people blocks away reacting to where the sound was coming from, it was cool to get their attention, it works for karaoke, sing while your song plays, amplifying your voice and the music volume equally, static appears while pressing mic button the wrong way. I woke my neighbors up talking with it on high and one of them told me he thought it was God talking to him. It definitely gets peoples attention if this is what your after. The quality is less than desirable, it doesn't last long enough for me to buy another one since I never used it much that it should have quit working without much total use. This quit working using batteries, then it quit working being plugged in, it was not a blown fuse causing it to stop working. I ordered another one while it worked and decided to refuse shipping on it after it quit working all together before it arrived. If it was 100 dollars okay but not close to 300 no. It is somewhat cheap quality design that NEEDS REVAMPING.

I'm not sure if my expectations were higher or if this is just what a "LOUD" megaphone is. It is loud when using the siren but when using the microphone it seems it could be louder. Could be that any louder in this form factor may cause distortion but overall it is a solid performer for the price.

Excellent, although only two things I would change would be: 1. the location of the siren button is too close to the carrying handle and makes it very, very easy to accidentally turn on the siren when either reaching for it or just carrying it around. 2. The activation button on the microphone does not go up and down distinctly and often gets stuck in the down (on) position with it being very difficult to jiggle a bit to make it pop back up. Can then deplete batteries very quickly. Loudness is great however and is pretty durable relative to many other megaphones on the market, which are the biggest things I was looking for.
