The small USB adapter for car power outlet has a conventional USB 2.0 port, and a spiral cable with a micro-USB connector. The spiral cable has a length of about 30cm and can be stretched without problems on 100cm. At the cable can be connected and recharge almost all smartphones. The Poweradd adapter is very compact and makes a high quality impression. Compared to many cheap car adapters, this does not interfere with radio reception and CE approved. I am thrilled with the USB car adapter. Thanks to the Micro USB spiral cable no spaghetti wires in the vehicle.
