Am I right in thinking the way to run a 12V compressor fridge when on hook up is via the leisure battery and a permanently installed battery charger? Waeco, for 'tis they, would sell me an expensive mains adapter, but in view of above I hope I won't need one. So if you guys wouldn't mind running through this again because I wasn't listening the other 100 times it's been discussed... What charger for above would you recommend? If I have say one twin socket in the van and above charger wired in, can anyone recommend the smallest consumer unit that has (or room for and no more) the correct (double pole??) MCB's and earth thingamies I need?
