The FlexLight can be powered by three (included) AAA batteries or by this AC-Adapter. Includes a 10 foot long cable that can plug into any 5V-output USB port, from the included wall adapter unit* to portable battery supplies or computer USB ports.

*The Flex-Light using AAA batteries is not designed to recharge batteries, even if rechargeable AAA batteries are inserted. The light bypasses the batteries when the power supply is plugged in.
