DJI Mavic Air 2 & Air 2S Smart Battery Charger - 3-in-1 Fast Charging Hub for Drone Batteries & Remote Controller - Perfect for Travel, Aerial Photography & Outdoor Adventures

This charger saves a ton of time since I can charge all my batteries at once before going flying. If you are only charging a single battery then the stock DJI charger is probably a bit faster since it puts out 2.8 amps and this one puts out 2 amps at each plug. The lower amperage is probably better for your batteries anyway... and who cares when you can charge 4 batteries in 100 minutes on this charger compared to 1 battery in 90 minutes on the DJI charger.
