My cigarette is usually occupied by the Navi-charger cable, therefore had to operate in the winter a heating pad can an adapter ago. The decision was made on the offered distribution due to the favorable price and the compact plug. The first impression was quite positive, even if the description on the package was not satisfactory (the cable length is incorrect, a maximum power consumption not specified). Disillusionment was then carried out, however, when operating in the car where after a short time heated strongly suspect the connection cable. After disassembly - here it should be mentioned positively that neither male nor adapters are welded firmly but simply screwed - it became apparent that the adapter while protected by a 6A miniature fuse, use a wire, however, is dimensioned by the cross-sectional ago more for lighting a Christmas crib. Whether only the fuse or the cable would blow seems questionable to me. The USB powered I have not tested. After changing the cable, the adapter does its job properly now, due to the low price and the hobbyist Freud Lichen structure therefore two stars - I can in good conscience recommend the product, however.
