Cheap acting, low in price, defective in use quickly

Bought in October 2012 for the Samsung Galaxy S3 as an emergency charger me the cable.
The idea was, if the mobile phone once the go power requires a matching charger near to have.
The shipping was fast and the cable neatly packaged.
A charge of a nearly empty battery lasted just over 2 hours. That's much faster than by original charge cable via socket.
From the fit ago nothing has let complain; neither the contact to phone, even the car jack.

After more than 15 charges it happened:
The next time you plug in there was a bang. The red charging lamp did not, as did not load the phone. Other devices were also no longer being charged per car socket ... hmmm, security? Assurance !!! -> 30A fuse flew.
Replace fuse, try again -> Paeng .... -.-
Charging cable screwed apart and looked at the local backup without damage. But lo and behold, the inner wall of the thinnest plastic was broken and the current bridged quite cheeky and shameless securing inboard. Plus Minus met. This can not go well, eventually mingled always heroically the vehicle security and offered to all our benefit.

Conclusion: A built-in fuse is good, but useless if "material error" bridge the fuse. Since so can end up somewhat dangerous, for safety's sake only 1 star. I also bemängle the short shelf life of the product, which now finds itself located on a hill next to full diapers and herringbone.
Another product begins with H and ends with AMA now replaced this unit.
