I picked this charger, because it can also be operated in the vehicle, via the cigarette lighter. It has a very good charging performance with AA 2700 mAh, also in the car, so that the batteries can be recharged quickly during outdoor play with terrain buggies or flight models. That's a really great idea by the manufacturer that makes me a lot of joy. I would buy this unit at any time because it is delivered super well packaged within 3 days.
