DJI Air 3 Battery Charging Hub.

The battery charging hub supports a new power accumulation function, which can transfer the remaining power from multiple batteries to the battery with the highest remaining power. When connected to a designated charger, the battery charging hub can expand the charging interface to three, and enhances efficiency by charging batteries in sequence according to their remaining power level, with more fully-charged batteries receiving power first. The battery charging hub can also quickly charge remote controllers, smartphones, and other devices.
