Charger works and does what it should, charge the battery. Charging time about 5-6 hours. The beliegende plug adapter not locked after insertion into the charger unfortunately. So it happens that the charger when using slips into a wall socket by its own weight downwards from the adapter. Problem can be resolved when the device is rotated by 180 ° plugged into the outlet. Some outlets I have contact problems with my device. Upon complete insertion into the socket the contact is gone. Does not matter if the device is again pulled out a piece of it works, though a bit wobbly. For the price, the weaknesses in my view, however, are easy to handle.
