- The beep to confirm the smartphone recognition is quite noisy. Definitely not Office-compatible, if you do not want to upset his colleagues. I've opened times - the beeper is so small and soldered that it is impossible to disconnect him to lay barren otherwise dead. Too bad!
- The device is quite warm during the charging process, which in the long run is certainly not particularly conducive to the battery, as it sometimes is now exactly about. On the other side it cools course relatively quickly after switching off the charge current again.
Apart from the device detects clean the charging end with my Nexus 5 and looks chic.
Who Heat And Noise care are allowed to access here. My recommendation (at least for a Nexus4 / 5) but would be the RP-WCN7.von RAVPower.
