Can Inverters for Outdoor Races?

[bretts]

nope, just get a cheap 12v car battery charger and make sure it's charged the night before.

Then just use croc clips on the terminals to give you power to your charger. All assuming you're charger accepts 12v input. no need to go anywhere near your road car battery.

it's the way we all did it back in the day as nowhere allowed us to use mains supply and also all the chargers where only 12v input (unless you where rich)
