thank you for clearing it up I been wondering about it for very long time and few times I was even thinking okay I have some old PC lets do the experiment does it work in USB 3 but luckily I was always too lazy to try it out ... is too many watts only problem with it ? I mean because cable is same it kind of makes me think ... I feel like a baby with couple of nails in my hand and everybody screaming DONT STICK NAILS INTO WALL PLUG
