I got myself the power plug to it to be able to connect the Enermax Aeolus CP003-G Premium notebook cooler that my AV Receivers Yamaha RX 3010 cools. As soon as the plug is in the socket, it is indicated by three small red diode that he now is live - I have to recognize no charge indicator also with other devices. Thus, the connector no automatic charging has defnitiv as one might believe supposedly. OA cooler it can provide easily with power, tend to, I even feel that he now runs faster and rounder than before on a normal USB device connector - a good thing. The fact that the power plug has only one USB port, it can be universally fitted with cables, has the added advantage that the transport has not bent the chassis cable more. In terms of build quality, I can not yet see any flaws. The size of the male body is so narrow, the adjacent outlets are not obstructed and you can grab him well nonetheless. For my needs, this was a very good buy, and so far I have not had problems with the quality - but I must admit that he so far only a few times into the power outlet and has been put back out because he just most of the time there remains.
