The charger is supplied in a box any printed English and Spanish. the pictures on the outside do not fully correspond to the model in it. The first time you touch one still has the impression of having a cheap piece of plastic in my hand here - but the impression is deceptive. I use now for several Wochne the "Universal Charger" regularly since in my mobile power socket is defective. The external loading with the device and using an interchangeable battery, 24 hours cell phone usage are now back guarantee. The charger itself can be one hand to use for charging, the LCD display can be used as a battery level indicator. Current concerns the charger from three alternative sources: 1. Normal, fold-out plug for the socket, 2, 12V - connection also at the back for the car. 3. USB jack on the side. Plug and USB I have already used; the Ladergebnisse are equally good. The battery is kept stable with a fixed Plasikklemme. with two small slides can position the contacts on the battery contacts. Correct polarity must not pay attention to the unit "recognizes" this automatically. Here I find the only drawback: The contacts may have somewhat windy and can bend. On the other hand are a reasonable price, prompt delivery, compact dimensions. stable housing, charge status testing, variable power connection options. Buy recommendation!
