If anyone is interested, they are selling the Alpicool X50s again on Amazon as a deal day for £135. Can be used as a freezer or a fridge, freezes to -19C. I bought one of these last month and tested it, works quite well, but not been on a trip with it yet (next week ). Tested the temperature down to -19C (unit said -20C) and generally temperature is within 1 degree of the unit readout. Kept its temperature for about 2-3 hours without power.
Power requirements are supposedly 440W for 24h @ 25C = ~ 1.5Ah (37A per day). I'll report back in this after my trip.
hope this helps someone!
