I wanted to use the adapter for other purposes. (Voltage transformer from 12 to 5 volts for a Raspberry Pi) After joining once did nothing. For the price, the quarrel is not worthwhile. So open, looked inside, and scared. Several solder joints were not soldered correctly, the components on the circuit board wobbled back and forth. I have the defective solder joints repaired, now do that for which it was purchased. Due to the lack housing I have even saved some space. But as a charger in the car he was, just as he came, not suitable.
