Not bad as an external charger and a phone holder

Charging a battery compartment in the charging station works in fact; a nearly empty 1500mAh battery was full again after about 3 hours. This fits with the supplied power supply that delivers 500mA.

But that is precisely the problem: 500mA are not enough to simultaneously provide a battery in the tray and a telephone. Then, the instruction manual even out - but to reduce cable clutter on your desk, it does not contribute if you still the original power supply from Samsung needs to the paper loaded in the phone battery and the paper loaded in the tray of the docking station battery to loading ...

That seems the manufacturer also to be aware of: The operating instructions (an A5 sheet, printed on both sides) has three times indicates that you should not try to connect the docking station at the same time with a USB port of a computer and the power supply. Correctly - that could lead to damage to the computer or the power adapter. But that is mentioned, the suspicion suggests that one or the other buyer has been looking for ways to provide a phone on the dock with electricity when simultaneously charging a battery pack. (It is worth noting that it would be impossible with conventional cables to connect the USB port on the docking station at the same time to a USB port and the power adapter, so do not worry the "everyday use".)

As others have stated, the cable has fallen quite short to connect the phone to the docking station. If Samsung's USB port in the phone only soldered, and not additionally with screws or fixed like has (I believe the former to be more likely to think of it, with how much electronics as a modern mobile phone is crammed - for Extra screw is little space ), then I see the danger that the USB plug is a bit too mechanically loaded to dock through the cable, which could lead in the end to the fact that one or the other pin of the plug is released by fatigue of solder from the PCB. Were a little pity for a few hundred euros expensive device ...

Seen are the actually scarce 500mA of power supply but no problem - the phone itself you should in any case better connect its own USB cable to your PC, or use the original Samsung PSU. (This, incidentally, delivers 700mA.)

Another detail: If the docking station is connected to a PC or the Netzeil, but is no battery in the charging compartment, the charging status LED flashes quite nervous in green and red, which I find quite irritating when the machine on the desk next to the LCD screen stands. The but you can also see positive: As the docking station then needlessly consumes power, I understand that as a reminder: "Dude, take the power supply of the docking station from the socket - it consumes unnecessary power now!"
