Protects the PS4 controller, saving power (measured enclosed)

Explanations:
1. The PS4 controllers are spared because they are with the charging station is not on the sensitive micro-USB port (such as the PS4) charged, but the less sensitive EXT port. It must here so no fummeliges microUSB cables are pressed gently but firmly into the controller, but the controller glide smoothly on the generously dimensioned EXT port. In addition, the charging station has obviously a protection circuit that prevents the Li-Ion batteries, the controller be kept at 100% load (premature aging): The controller batteries are only recharged when the battery charge defined under a level drops (approximately 90%).
EDIT (2014): The protection circuit does not appear to sit in the charging station, but in the controllers themselves: In the meantime, I've found that they also exhibit this behavior positive charge on the PC.

2. The loading of the controllers in this charging station directly to the socket saves against the charging of the PS4 (in standby mode) power, even measured consumption:
PS4 invites Controller in standby mode: 14 watts
PS4 with loaded controller in standby mode: 7.5 Watt
Dock recharges Controller: 4.5 Watt
Charging station with loaded Controller: approx 0-0.5 watts (hardly measurable)

3. The charging station is high-quality, secure or has a space-saving design. Yet discreet allows two controllers simultaneously hardly recharge and store.

I highly recommend this charging station so in good conscience recommend - but not to the inflated prices that are partly demanded it. More than 30 euros I would not have to spend (I paid for a special few euros less).
