Since it (at least for now) are the cradle of Samsung only in white and I actually the Zens loader simple and nice find designed, I decided for this place the Samsung part.
The charger works perfectly with the Samsung S4 (and the appropriate back cover). Your phone will find the station and briefly displays the charging starts. When the battery is full, the charger turns off. My phone displays after charging 100%. Cancel the operation or not, I can not confirm fully charge so. Placing the phone is also no precision work; simply forking out, wrong or slip does not matter.
If you listen very closely, you can hear a faint ticking during charging. However, this does not interfere with and is only audible if one keeps his ear immediately close to the apparatus.
That the LEDLight is not so much light, I find actually an advantage. Therefore, it interferes not if you have the charger at night in the bedroom.
Conclusion: if that Samsung charger does not fit because of the size or color is in the Zens a stylish alternative.
