it's a beautiful product with a beautiful nice design, just not possible to put the samsung s3 vertically "precarious balance" in no worries horizontal finally it can charge another battery in just under 2 hours to 2 hours 30 so totally empty ... Samsung could have added a dock to charge and the battery and the smartphone with a separate load for either the: you must buy another bracket for samsung galaxy s3 dock even more material to ask ... otherwise happy and easy to use can be emmene anywhere via USB or AC load ++ provided by the phone.
