Thanks all, appreciated.
The fridge is a waeco, mobicool, 12/24vdc 0.3w. Its wired straight from the leisure battery I think with a separate isolating switch.
So is it OK to use a smart charger plugged directly into the 240v outlet into the leisure battery? And presumably ensure the rocker is in the neutral position so it's not being charged twice?
And would it make any odds if I'm in Europe, ie does the pms still output enough from the 3pin plug socket?
And so with a pms when you're driving around the leisure battery is not being charged? Or only negligible charge?
Thanks again,
Ollie
