Thought this might be the best group for an idea on keeping power to an ARB type Cooler / Freezer during travel. Having to make a quick trip so I don't have much time to plan. We typically take a 12v powered cooler/freezer, like an ARB, on our long trips. Our 12v sockets switch off with the engine but I'd like to keep the cooler in the vehicle overnight as it's heavy and I'm tired of lugging it into our place of stay each night. I could bring a spare battery to keep it operating but the spare will eventually run out so I need a way to charge it as we travel. Is there a 12v socket to a 12v battery charger that I should use as we're driving?
