This power adapter plugs into a standard 100 to 240V wall outlet (cable not included) and can recharge either your FPV Intelligent Flight Battery, remote controller, or goggles battery. A built-in USB port gives you the added ability to recharge a second mobile device at the same time, such as a smartphone or tablet. Without a second device charging, this adapter can recharge a flight battery in approximately 50 minutes or the remote or goggles in approximately two hours and 30 minutes.
