Smartphone is an actual Windows Phone Lumia 830 that the corresponding wireless Qi charging technology has been installed at the factory.
The addition in the package purchased associated Ladegereät (1500 mA) was easily connected / plugged in and off we went. It fits any sufficiently sized USB charger.
After connecting the front of the pad built LED lights, as indicated, in Standby "green".
Then the smartphone without major adjustment or fumbling hung up, the LED switched immediately to "blue" (store) and that's it fortunately already.
Since then, work not only charging problems (Smartphone in the shell), but after the end of the charging process enters the loader fortunately also in the mode "trickle charge" (the charging pad will change alternately at certain intervals between Standby "green" and shop "blue") ,
Charging also seems to work amazingly fast and in fact 100% to reach (Ad Mobile Phone). As I invite mostly overnight, the smart phone is always fully charged in the morning. Amn .: 4 as permissible distance between the charger and Smartphone - 10 mm called (envelope!).
Should the smartphone once have placed too far off-center, so that a charge can no longer occur, the charging LED will flash to indicate an error "blue" and the phone does not exist after you hang up the characteristic "Charging beep" of itself.
Any noise or sounds of Ladepads are not heard during charging (important as it is right for me next to the bed on the nightstand), the charger also does not heat up at me significantly. The switching on and off the charging process takes place silently on the part of the charger, only the smartphone touch with me once to start charging when placed.
All in all a very positive impression, therefore from my side at this time (after 5 days) a full "recommendation" and 5 star.
Update 5/19/2016:
There is now my hand experience before in combination with the Microsoft (Nokia) Lumia 830. Quite as rosy as in the beginning, it no longer looks as regards the charging behavior, because sometimes nothing has happened in the nightly charge. For example, although the charge with 10.8% is displayed, the phone continues to discharge, according to the charging curve, so that the state of charge the next morning is depressants than previously. This works sometimes and then again not, the presumption on my part that the QI functionality between the two devices is not working properly. The suspicion is directed here to the Nokia, but without knowing further details.
