The device is working properly, iPhone and iPad loads reliably and keeps very long through. Loading however takes his time. If the part is empty, then you have to have it one night hanging grid. It is useful to have a slightly stronger power supply, as it is the standard Apple power supply. The battery is quite difficult, especially in a ladies handbag it is clearly noticeable. Otherwise, processing is very high. The lamp is in my opinion a little more useful gimmick.
