Hi CrispinCrispin said:but, (assuming) this is a normal travel 12V fridge such as a waeco, Engel or similar, their current there is nothing wrong with doing it this way? (or is there?)
having a quick look at the Engel website, the 40L pulls 2.5A on 12V. You could assume this is only when the compressor is running, which is hopefully not very often.
Whenever it kicks in, it would use the battery and the charger would just top it back up.
I've used this arrangement many times (not exactly the same) without any hassle.
Also, would using a regulated PSU set at 13.8 not fully charge a battery? They should be charged to 14.2V and then held at 13.8V (which is the trickle feature)while on standby (which is essentially what this would be doing)
if we talking double door fridge freezer here, I stand corrected

I have the Multi XS 7000, which seems to do everything that you'd need. A few of my friends have them and they are very impressed with them, including one who uses his in his professional workshop and says he couldn't be without it, especially the 12v maintain function, very handy to keep the battery voltage constant during ECU reprogramming.
I sourced mine from Apb trading: http://www.expedition-equipment.com/ind ... 1&Itemid=1
