PylePyle Portable Megaphone Bullhorn Speaker - 50W, 1200 Yard Range, Built-in Siren

Everything works on it fine but you will have to recharge it daily unless you put batteries in it which you could use for about 2 to 3 days

Me llegó descompuesto, ni siquiera enciende

This was sold very cheap on Amazon warehouse returns. The megaphone was in good shape aside from some where on the logo on the one side and a slightly defective rechargeable battery. Fortunately, the battery pack came apart and the pieces could be pushed back into place so that the pins made contact. It uses one 18650 lithium ion cell and a boost circuit to put the voltage up to 7.4v, has a flip out USB plug for charging - I had to use my own USB charger. Otherwise you can run the bull horn on four c batteries, which would probably last longer. Loud enough for the $10 bargain price, no music playing capability - I don't know why the listing mentioned music. Handle folds down. A competent unit, satisfied! LATER: As noted by another reviewer, the rechargeable battery pack self-discharges overnight. Lose 1 star.

Did not work, very poor quality

Looks great and functions fine. The handle can pop in to save storage space. You can push a button to set off a siren that always gets immediate attention from my audience. Removable USB compatible charging piece is handy. Only downside is the battery will die from one day to the next, so a good hour pre-charge is mandatory.
