Review on 🔊 Sleek Black Wireless Solar Bluetooth Speaker for Seamless Connectivity with iOS, Androids, Phones, Tablets, and Computers by Elizabeth Brooks

Works well and USB charging is very fast. Consumes battery power and can run for hours on each charge as long as the sun shines on the panel. Although a previous customer left a negative review for this speaker, it also charges my smartphone and USB rechargeable bike lights via the USB port. Note: Please make sure the speaker is charged before connecting your phone or other electronic devices via the USB port, otherwise your device will not charge; besides, it's good. I recommend this speaker to everyone.
