The Mavic Air 2 Charging Hub does not include a power supply. Please use an official DJI Mavic Air 2 power supply with this device. When connected to a Mavic Air 2 charger or car charger, the Mavic Air 2 Battery Charging Hub can be expanded to charge three additional batteries. The battery charging hub enhances efficiency by charging batteries in sequence according to their remaining power level, with more fully-charged batteries receiving power first.
