I have a whole bunch of Qi tried stations for the G3. Due to the size of the unit, it was not easy to find something where the phone for a reasonable loads (unfortunately the loading point is not centered) and the other reasons were often in the game, which I would have never thought in life. On the Zen mat the phone was VERY hot! The Adata CE700 is on the one hand to smooth and slipped easily and on the other hand you have to let through the G3 very far (otherwise a great charging pad). Ravpower I also found a total firstonce class. Well finished, matt surface, quite bright LEDs but ... it beeps. That it does so loud, that's it became my wife always awake. For the living room would be a great device, but not for the bedroom.
From Choetech I tested two stations. These and a coil. With the simple version I got displayed only a "slow loading".
The mat with 3 coils I can now recommend after a long search. The mobile phone is only slightly warm, discreet size, matt surface and it loads quickly and in almost all positions. The only drawback here, too: The LED is relatively bright I will probably paint over with Edding, so the bedroom is not blue.. But this is the smallest problem.
All in all a strong buy recommendation for the G3 from LG.
