Looking on amazon i can only found hdmi splitters that plugs are in electrical outlet. I can find things with eu plug but one time i will run out of plugs(i have 4(energy splitter- if i add another its a little risky to have a lot of devices connected in the same plug)wiiu,pc,monitor,splitter and when i want to charge something?). IS there some hdmi splitter with usb power or usb power isnt enough? Thanks.
