This charger should accompany each drone in its packaging. Can charge the battery without using the drone drone. Loading is again not ... USB AC charger is too much to ask ... The USB cable is only 20cm ... again too short to be truly useful. I find abused, and at the limit of the scam of having to buy this charger and plug it duty in addition to either a PC or to a USB AC charger or universal smartphone. Also counting the price of the battery provided (14.99 euros), the charger costs 5 euros, as saying that for this price would largely Parrot could provide it with all the drones. The battery supplied with work are done. My personal rating: 17/20.
