Repeat after me,,,,,,
All fridges will sap your battery,,,,,, All fridges will sap your battery,,,repeat at will.
CRX50 will stilllllllll sap your battery, but not quite as much as others.
The older or cheaper the cooling device, usually the more it will sap your,,,,battery .
A leisure battery will help by providing a supply of juice, two batteries will help a bit more etc etc.
Driving around and charging them will help, but you’d have to drive a fair old way to re charge a battery but every drive puts in a bit.
Solar will re charge your battery every single day if you have enough of an array of solar panels but as above, every little bit helps. The sunnier it is, the more they give, but the sunnier it is the more the fridge is in competition with the warmer temperatures.
The ultimate set up at the moment ‘seems’ to be if there’s no other energy available (hook up) or three way. A leisure battery that will let you have about a half of its capacity or two or more regular leisure batteries then there’s the extra expensive super duper leisure battery lithium iron which will let you have a bit more at roughly ten times the price. So the more expensive battery is giving you more juice but taking up less space, or just take loads of batteries if space isn’t an issue.
Your solar array could start at 20 Watts but wouldn’t help much at all. Starting point should be in the one hundred watts area or more then you have the fixed / portable issue / question, mainly because a panel facing the sun will collect a fair bit more, if you can be bothered moving it about.
So three to four days is achievable with a new deep cycle battery fully charged, with a hundred watts plus solar panel, all powering a CRX50 on the proviso that you don’t keep chucking too much warm stuff in the fridge and making it work hard. Some peeps will buy frozen food while touring to help cool the fridge as the frozen food defrosts prior to cooking, not a bad idea for sure.
