What is Reddit's opinion of Maxplay-play Wii U on board?

From 3.5 billion Reddit comments

ok, so this would be better to power the wii u? www.amazon.com/Maxplay-play-Wii-U-board/dp/B00JCJBOWI/

and also, do you have a good battery that would last a little longer than two hours (3-4)? I know it would take a while to charge, so I only plan a playing a few times a week. Thanks for the info!

This and perhaps this for away from vehicle play.

Might not be AS portable but hey, saved ya $250. :)
