The week the Beta starts, I'm driving to Boston. I don't want to miss out, so I plan on playing my PS4 in the car while we drive. My car won't support a PS4's power needs for more than 10 minutes. If the drive is say, 8 hours, what size battery would I need to sufficiently sustain online play for that amount of time? Price isn't an issue. If you could recommend a wifi USB for the drive, that would helpful as well.
