Appointed on 22:12:13, announced delivery 2.1.-7.1.14. Actual delivery already on 31.12.13. I use the charging pad with my Nexus 4. It works flawlessly. As described in other reviews, the pad acknowledged the correct placement of the phone with a short beep, but not so loud that it interferes with us in the bedroom. It has a status LED, which lights up green when ready indicator, loading them is blue. In the bedroom, the man may be disturbing, but it is not very bright. Who you really are disturbing, it can indeed taping. I've had enough already but when I lay my cell phone so that it covers the LED. The delivery is as stated in the article description, include a USB charger, I use it with the adapter that comes with the phone. The energy efficiency of Induktionspads is specified in the manual with> 72%. That also seems to fit. The power consumption at 90% state of charge was charging via USB directly from approximately 3.6W, via the pad at approximately one watt more. (Measured with a Voltcraft Energy Check 3000 directly to the wall socket) When the battery is fully charged, uses a trickle charge. The LED changes in ungegelmäßigen cycles, usually between 10 and 50 seconds between green and blue. During the charging phase the Leisungsaufnahme is approximately 1.2 W. The proportion of the charging phases lies at below 50%, I guess the average power for trickle charging in approximately 0.5 W. In the user manual the type designation T200 appears, visually it seems to be identical with the other offered on Amazon Ladepads.
