 that you need to run what you want. If you're camping a lot and you use this on the road and you'd like to use something heavier, maybe get a 1,000-watt inverter if you've got a 700-watt heater. But then those have to be plugged into the battery. Yeah, so I would do that. I would get it run to the battery. There are places through the firewall which you can run a power and ground that's fused at the battery on these to protect the cables.
