The DJI Parallel Charging Hub for Flip is a great accessory for owners of two or more Flip intelligent flight batteries. The hub can hold up to four intelligent flight batteries, and with an optional 65W power adapter and USB-C cable, it can recharge up to two simultaneously. If you need one battery charged as fast as possible, the hub can charge them in sequence instead. A cool additional feature is the ability to act like a power bank for your mobile devices. With at least one battery in the hub, simply connect your mobile device via USB-C.
