Bought a Sharp MP 30 laptop (10.4" screen) for my H2. Got the Verizon PC5220 wireless broadband card so linked up driving down the road! Works very well. Soooo, decided to add a 115V AC outlet to the H2. Used a Radio Shack 220 watt inverter. That runs most portable appliances. If you do this and want more wattage be careful. Inverters go up in size in direct relation to the wattage & that was the biggest problem, finding a place to hide the inverter. Ended up in the rear of the console and just did fit (tightly). I used the inverter end plate with the receptacle & switch as the mounting plate in the H2 panel & just extended the wires & made a new end plate for the inverter. Here's some pics of the install & final result. I'm posting this from my H2!
P.S. The MP 30 has some neat features. Plays dvd's without even booting up the OS! Weighs a total of 2.8 pounds. Sorry DRTY...it's not a MAC.
