At first I had ordered my original Samsung charging pad, which never fully charges the battery, however. Actually, I did not mind but if you phone 2 or 3 days do not need (yes, dear children, such people there are .... :-)) then it is already annoying, strike out with 50% battery power, because the Samsung charging pad no trickle charge offers. With the T900-charging station has now changed that. The battery is fully charged and received the charge also. Even sad that one of the largest brand manufacturers small Krauter must be by a show (No offense!), How to do it right.
Connected to the original charger by Samsung, the device loads my Galaxy S5 fast and is even minimally warm. This is normal for inductive loads, is also mentioned explicit in the instruction manual. Damage to the battery or other parts I do not fear for it. When the phone is in the sun, it is sometimes even warmer.
The operation of the charging station is very simple: connect the phone's charge / power supply to the charging station, hang up phone vertically or horizontally - that's it! Sounds like buzzing, humming, etc. I can not perceive.
Conclusion: A good buy!
Addendum 12.04.2014:
The charger is still running smoothly, so I've ordered a second unit for the office. Connected - runs!
