a friend of mine has the last generation MSI variant...basically the GE 62 MVR 7RG that i rock, but in backpack style. and he doesn't VR. he uses it as the ultimate LANbox

Why not just buy the wireless adapter and use a desktop or laptop plugged in to the wall? I can't imagine those batteries last that long and that whole set up is probably really heavy after 20-30 minutes worth of use. Unless of course the batteries die before then.
