I've got my Nexus 5 now repeatedly and successfully loaded with the Zens Charger ZESC02B. The smartphone just lie on the station and the charging begins. The positioning is very simple. The device must not be exactly in the middle for detection and charge. Charging with Case (Ringke Slim) also works without problems. I invite overnight. The Nexus 5 has the morning always 100% battery charge. A Selbstendladung described as in some reviews I could not tell. Excellent! The station is with me on the nightstand beside the bed. Without the smartphone the station LED is off, orange in the detection of the device (about 0.5s) and while charging it glows green restrained and interfere (me) not the (single) sleep. Very important point, as I am in this respect somewhat sensitive. The wireless charging also works when the Nexus 5 is turned off (eg for battery completely empty). While that is a plus point of the Nexus 5, although I am pleased in this context but very, I therefore need the charging cable never again.
I am completely satisfied and would highly recommend this charging station.
