The discreet (only protrudes slightly from the cigarette lighter hole) plug acts as an adapter for a standard USB port. There you can then connect a cable which possibly ends in a micro / mini USB port. In this case, just a micro-USB cable is included. The cable itself is much fexible and longer than the supplied when Ray, so you can use at home and pack the car the supplied it.
A little bit annoying the arg bright green diode starts the loading. At night a bit annoying - can, however, cover, and an indicator that the adapter has juice is then again positive.
Strong buy recommendation.
