Review on 🔊 Totola Wireless Bluetooth Speaker - AUX/USB/TF Card Slot - Outdoor Portable Stereo Speaker with HD Audio and Enhanced Bass - Dual-Driver - Handsfree Calling - FM Radio Speaker for Travel and Party (Black) by Sara Bertrand

I bought this speaker for school. I wanted something to take outside but not expensive as I will use it for the kids. The speaker was fully charged but stopped working after 1 song. I turned it off and on again but it died again after 1 song. It works well when the USB is plugged into the computer and it's constantly charging, but when you use it that way there's a constant hum.
