The Wii U Gamepad has often been confused to be a dedicated hand held system. The reality we all know however is that it can only works when it's in close proximity to the actual system--which depends power. Now we can finally break free of that power plug and make our Wii U go mobile...on wheels.
Max Play is a power adapter that lets your Wii U work via car charger. Isn't that bad for the car you ask? Well keep in mind the Wii U only uses 33 WATS (around half that of the PS3 or Xbox 360) making it very car friendly. The only downside? All those wires. Damn.
