Does anyone know if the 115v AC outlet is backed up by the main drive battery on the 4xe or just the 12v starter battery? Trying to figure out how much juice I can get from it without the engine running. One would think the main drive battery, but I know the non-Xe's have the same plug.

Through some research, it does look like the 4xe has the benefit of the 12v battery being backed up by the main drive battery through the DC-DC converter module. That's how the 12v is charged on the 4xe's, since there is no 12v alternator.

I'm not as concerned about the low wattage rating on the 115v. More about the total amp-hrs behind that without running the engine. In theory, it should be the 12v + main drive battery. Wish I could know for sure.....
