Anyone used a Mobicool W45 cooler?

Hey folks,

So we're looking at this cooler and trying to decide how well it would work for camping. It's battery powered and can charge on car batteries while the car's running. I have no idea how long the battery lasts after it's charged, though, or how long it takes to charge it.

I've already checked the instruction manual and online and found precisely nothing useful. Anybody used one of these?
