So I bought this PSU for the Raspberry 2. 5V and 2A were for my needs enough. Basically the Rasp works so well. I had, however, always problems with a connected hard drive in the USB enclosure (2.5-inch SSD Samsung Pro 830, total power consumption of 100 mAh). This was actually never really recognized. Buying a powered USB hub then solved the problem. Now I have something herumprobiert and have another power supply used (5V 1A). So strangely enough, the SSD was properly always recognized the USB port of Raspberry. Now I have reused the Goobay power supply and thus it did not work again. The answer was then but the power supply. There is 5.25V from (also according to the nameplate affixed). This extends little more tension from then to cause these problems. So not suitable for use on Raspberry. But I still forgive four stars because it works so in principle and a constant voltage supplies.
