Try this one. It doesn't have an AC outlet. It has the input plug that plugs into the laptop to charge it. Although now that I'm looking closer, you may not be able to directly run a laptop off it, nor get a full charge. So consider a more powerful battery than this one, or more than one.
I also recommend a super capacitor jump starter. Those don't need to be kept charged to start your vehicle. Mine works better than the Grepro.
