Long after I have a holder for the N8 searched, offering mumbi then seemed to be the price-performance Optimum. After a few bad experiences with Far Eastern USB charging cables that were not usually in a position; Connect charging and data transfer, I was excited and pleasantly surprised after unpacking: Everything fits and works without blemish. Admittedly, the shape design fits more into the bakelite postwar period, but once the N8 is only once in the cradle, you can forgive the cosmetics quickly. The very solidly crafted PSU supplied brave the battery of the phone and probably still has power for longer so that you can safely consider it a source of strength for all eventualities; the USB-output of the power supply opens as many options. As I said, charging and data transfer function without power supply via USB, also through an intermediate hub. The additional mini-to-micro adapter completes the package; the way you want it. Delivery was prompt and free. What more do you want.
