RVi3 portable brake

What would be nice on the hub is an on/off switch. Fully charged, it's good for 10-12 hours I think. When you get to your destination it just discharges. You have to remember to charge it up the night before. I lay the tablet where the cupholders are on my E 450 rig, but I agree that thing is big. It does work well though. I was worried that being a wifi system it might lose signal etc. but that hasn't happened.
