DJI Air 3 - Battery Charging Hub

The battery charging hub supports a new energy accumulation function, which transfers the remaining energy from multiple batteries to the battery with the highest remaining energy. When connected to a designated charger, the Battery Charging Hub can expand the charging interface to three, and improves efficiency by charging batteries in sequence based on their remaining power level, with the most charged batteries receiving power first. The battery charging hub can also quickly charge remote controls, smartphones and other devices.
