Very good charger. The batteries charge within 15 mn.Très namely announced significant compared to my old charger which put an infinite time for refills. It is not bigger than the chargers that I used to use. Only the transformer can takes place. The only downside we could find is that the internal fan is quite noisy. For people with a light sleep, it should not put it in the room. Color LEDs indicate the status of the battery and its charging status. The ability to charge AA and AAA batteries at the same time is very convenient. The notice mentions that we should charge only brand battery charger but having done the test with various batteries (including old) I said that it works very well. This charger also has the potential to be used abroad for accepting a current of 100-240 V, ideal for traveling. Very convenient to use for all remote control batteries, including toys, avoiding a too long waiting times. Supplied with 4 AA batteries. No regret when this purchase.
