Doing its job. I would not know what I could say about the big Ladeferät, it seems to me as if it were perhaps a bit too weak; my HTC One needs a lot of time until it is full. 18/08/2013: My suspicions were confirmed: when I turn the Navi while mobile and drive to the charger, bring me my Navi app after some time the message: the App uses more power than the charger delivers! After I unplugged the power supply, I realized that is almost empty although you have plugged power supply, the battery from the phone.
That means for me: This power supply is not recommended! Must look for something reasonably me now!
