Flex LED Belt: battery and chargingUpdated an hour ago
The Flex LED Belt has a built-in 6000 mAh rechargeable battery. Charge it with the included USB-C cable and any standard 5V/2A USB phone charger (not included). A full charge takes about 4 hours. The indicators blink while charging and turn solid white when full. The belt won't run while it's charging, so unplug it before your session.
