Do you think my Celica could power an Xbox One S for very long? I want to install one but I'm worried about say if I played for an hour waiting for someone or taking a break from say a 10-hour drive, would my entire battery be depleted? Can I install a secondary battery? Whats the highest capacity battery you know of? Should I just stick with a ps2 slim? What about hooking up some discrete solar panels? Thanks in advance for the views and the replies!
