A group of friends and I are all going camping, and have some minor back-up power needs (and no generator). We're trying to figure out which of our cars is best to plug an inverter into: most efficient as a generator.
Some of the factors I imagine go into this:
- Is it a hybrid? I suspect that hybrids are generally better at turning fuel into electricity.
- Gas mileage per weight: a pseudo measure of fuel efficiency at idle
- Newer/Older: it's probably safe to assume that newer cars expect to be used as a source of electricity more often due to the screens, sound system, and charging ports all being in frequent use.
- What else? I don't expect this to be an exact science (though it would be nice). Just some general idea of who's car to plug into.
