This is a factory replacement of the included battery charger that came with your Mavic Air 2 from DJI. This battery charger only has a single charge lead which can be connected directly to your Mavic Air 2 battery to charge it, or it can be used to power the Mavic Air 2 Battery Charging Hub. This battery charger for the Mavic Air 2 drone also has a USB-A port allowing you to charge most common USB accessories. This battery charger does not come with the required wall cable, which must be purchased separately.
