I’ve got a 240/12v electric coolbox that I keep on mind pick-up whilst I’m working wherever.

I don’t rely on it as a proper fridge to keep meat etc fresh for more than a day, but it’s a decent bit of kit to have.

It gets very wet inside though, which isn’t ideal if I’m away for a week, as it will start to pong a bit.

Any tips for anything I could use to reduce the condensation inside?

More insulation on the outside.stick it in a bag for life full of kingspan. Reduce the differential between inside and outside same as you would if you had a metal roofed garage with condensation issues
