Review: Best Megaphone I've Used So Far - I work at a community college and every year for commencement, it is my responsibility to run the students through the rehearsal in the morning. The Student Life office usually gives me a small megaphone to use but it is never loud enough for all the students to hear me. I end up setting it aside and yelling (yes, its sad that my voice is louder than the crappy megaphones the college provides). By the end of the day, my voice is very tired. I bought this megaphone hoping it would be a lot louder than the little ones I've used in the past years because I don't want to yell anymore. I received the ThunderPower 450 last week and took it out on campus with a coworker to test it out. This megaphone is VERY loud. My coworker was able to clearly hear and understand me from over 100 yards away while I spoke into the mic at a normal volume without shouting or raising my voice. This is a little bit on the heavy side but very well constructed and with the shoulder strap, the weight is not an issue. Anyone purchasing this megaphone will not be disappointed with it. It is a high quality product and is VERY LOUD.
Review: Everything is in good working order and it seems loud enough to me - I just received this megaphone. Everything is in good working order and it seems loud enough to me. As a rowing referee, I will be putting this thing through some major tests! My first impression is that it is a little heavy - takes 8 C cell batteries, and larger than some of the other megaphones I've tried out. The key will be durability and how it deals with wet weather.

## Questions & Answers

**Q: How much does this megaphone weigh?**
A: It's approximately five pounds. What are you planning on using it for?

**Q: How long the batteries last if megaphone used all day?**
A: It works quite well...we don't use ours all day, but we haven't had to change batteries yet, and we use ours 5xweek for about 3 hours each day.

**Q: Is there a rechargeable battery pack that comes with this . . .I would buy it if it did. . .**
A: I purchased this megaphone 2 years ago. It takes 8 C batteries to operate. There is no rechargeable battery pack for this megaphone, that I'm aware of.  I use the megaphone probably 8-10 times a year, and when I use it, it is for a full day.  I'm still using the original set of batteries I purchased to operate the megaphone. At the end of the day when I've been using it, I take the batteries out and put them in a bag and let the battery case area dry out (I often have to use the megaphone in wet conditions). It has worked very well during this time following these procedures. I've had the megaphone out in extremely wet conditions during which I've tape a plastic bag over the speaker/battery area at the end and cut the rest of the bag off. The megaphone works well during this as well. My biggest complaint about the megaphone is that it is heavy. It is also large. I would prefer a smaller, lighter model, but this thing works and it is loud, so it gets the job done.

**Q: Is the megaphone waterproof?**
A: No, that Megaphone is not waterproof.  When the microphone gets wet it will stop working.  However, once dry it worked again.  I used it in the rain and in leaky jon boats.  The solution was to wrap the microphone in plastic when it rains and avoid getting the microphone wet.  The alternative was to purchase a real waterproof megaphone at 4x the cost.   Actually my biggest complaint about that megaphone was the switch that toggled between siren, voice, and whistle.  It was way too easy to bump it.

### ⭐ Defective Product
*by M***W on March 27, 2024*

Bought this as a christmas gift, and when it was opened and used for the first time a month later it was discovered that it was broken. There is corrosion inside the battery compartment, the battery latch doesn't properly connect, and even when the battery compartment is held shut, the megaphone only generates quiet, almost rhythmic clicking noises and will not project any other sound. Moral of the story - check your purchase for defects as soon as it arrives.
