Personally I would forget about the Hybrid Version, especialy if you are going to Southern Europe.
The Waeco CK40D CoolFun (non Hybrid version) would have been my portable fridge of choice, as I liked the idea of the Digital Display and Push Button settings, but could not get one at the time.
We got the Mobicool C40 (not B40) from Obelink for £139 inc delivery to UK, that was back in 2013.
And used it as a tempory freezer for a month when we moved house, needles to say it worked fine as a freezer.
If you need 12/24v then the Waeco FR-35 is a good buy, being cheaper than the Waeco CF-35 CoolFreeze but otherwise the same item, but price will be £250 upwards.
We have the 230v ck40, I guess it's quite old as doesn't have a digital display just a dial to adjust.
As we use it as a freezer I bought a cheap digital thermometer to put inside and found it didn't get down to the -15 during August last year. Knowing this we didn't bother with ice cream, meat was eaten within a few days, only frozen veg would be stored for longer and it did freeze our cool blocks.
