Review on 🔊 Waterproof Solar Bluetooth Speaker with 5000mAH Battery - Portable Wireless TWS, 12W Output, 50H Playtime, Bluetooth 5.0 - Ideal for Home Party, Shower, Car, Outdoor, Travel by Sameer Harder

This speaker connects to Bluetooth easily. It can be charged via USB or solar energy. The sound is pretty good, but I hear a slight hum when listening at low volume. I can't detect any hum when I turn up the volume. This is a great little portable speaker for the lake, by the fire, in the shower, or anywhere. And for the price I'm very satisfied. I would recommend it.
