It works great in the car and also at home, because i have adapted to charge the cigarette lighter type plug works, great charges, both batteries at the same time and faster than the dji charger, and from what i can tell it, doesn’t overheat, the batteries. This thing works: it has saved my life several times being able to charge from the car while driving to different flight destinations.
