Question: What kind of Lithium battery does it take? Does it use a pack of 18650s? What capacity is the battery pack?
Document: The megaphone portion works fine, but the rechargeable battery doesn't work and the MP3 connection broke after one use, without receiving any abuse. I am very disappointed. I feel this produce was very poorly made.
Positive:- weight is very light (wasn't sure, is packet empty box or with megaphone)- USB and SDcard function is cool :)Negative:- On box is &#34;including Charger&#34;, but acctually it missed. On battery is no information, witch charger can use- Microphone button not working correcly- bad suprise that need to pay also some &#34;packing&#34; fee (on site was &#34;free shiping&#34;)
Crap! flimsy and the battery gave out after only a handful of uses. Buyer warned!
I use this for my house in the woods to chase away deer and bears, the sire is very loud, easy to use. The megaphone carries a decent distance. (I have 15 heavily wooded acres and sometimes use to call my husband in for lunch hahaha)
Works amazingly way better than I thought and the rechargable battery last a long time. The USB input sd card and phone jack works perfect total reason I bought it
This bullhorn ws so much better than the previous one we had. It was loud enough for us to use for a pet show and parde we hold. The re-chargeable batte y made it so much lighter than one which can only be used with 8 C batteries. We hooked up an I-PAD to play songs for it to lead a parade and it worked fantastic. WE did not need the siren but it was good and loud when we tried it out!
worked great for coordinating activities at our youth camp. our activities director was glad to not have to scream to get everyone's attention.
We bought this for our high school P.E. dept. One teacher used it on a daily basis and took good care of it and was happy with the sound at first. While the exterior shell appears to be heavy duty the relays/contacts in the microphone corroded within a month. We cleaned them 3x the first semester to restore the sound. By the end of the first semester neither the microphone or the handle relays were working and we were unable to fix them.
VERY HANDY AND HAS VARIOUS WAYS TO PROYECT THEMESSAGE DESIRED. OUT INOUT IS LOUD ENOUGH FOR OUR NEEDS. OUTSTANDING EQUIPMENT AND GOOD PRICE
So far has worked well.
