They are all 110-220v. The BIG problem is the Zone for games and DVD's. All America is Zone 1.........we and bloody Europe are Zone 2, Zone 3 is Asia and Zone 4 is where 99% of people can't buy them!!!! Hope that helps all of you not aware that unless you buy a pirated game somewhere, which are hacked to all Zones, picking up a game or DVD in the USA will not play on your XBox One or PS4. Cheers, Jax
