I don't have an issue with voltage, just getting the correct outlet for my plugs. i need to run multiple external hard drives and I've done it before I just need the power strip my friend took by accident. I also use my mac here with no issues.Mattea said:I am from the US which has 110v. mains but was able to use a powermac in Argentina with no problem. The power supply for the Apple supports 220 as well as 110.
