As part of the purchase deal, I had the dealer install an 1800 watt inverter, mounted on the forward wall of the front storage compartment on the right side, and hard wire to selected outlets inside. That would keep your lap top going for a very long time. I have electric clocks, I don't want to have to keep resetting, and some other low draw items, such as phone chargers etc. So much easier than having to set it up every time you want to use it.
