Now, I know the Wii U is pretty power efficient, however, 15V (The DC voltage needed to power the console) is hard to come by. BUT, if there was such a battery bank, i.e., something like a universal laptop battery or something similar, wouldn't it be possible to make it portable-ish? I'm thinking something like having a backpack like thing to carry it in (a regular backpack wouldn't really work, it would get pretty toasty in there without more cooling) and just playing off the gamepad? Sure, the gamepad battery life would also be considered but the battery life, especially with an upgraded battery should be more than enough. I know, I know, the switch basically does what the whole Wii U does in a small tablet, BUT, some people don't want to spent $300 on a new console with a very limited library (yet, waiting for Xenoblade 2) From what I read, the Wii U uses even less power (watts) than the original Wii. And Wii portables are a thing. Another thing to go by, I heard that the Wii portables could go off of 5V battery banks due to the built in regulator boards it has inside of it. Might the Wii U have something similar? So that the strange 15V could be changed to something more doable, like 12V?
