2 controlled chargers. After several hesitation I decided to order from the trader for correct rating and comments. But big disappointment, 1 charger does not work at all !!! and the 2 nd load at the speed of a snail. If used simultaneously charging, the battery will empty anyway! Takes 7/8 for full load while max 3 / 4h with original charger. I'll get original charger in store, I will pay 10 eur more, but I have a charger that works !!! Do not get fooled! do not buy this product you will be disappointed !!!!
