Has anybody had experience with 12v power station (as opposed to battery boxes) shutting down when a 12v fridge stops due to being cold enough and then filling to restart. If so how did you overcome the problem?

Are you sure it's not the fridge stopping because the so called Power Station ( it's not able to replenish itself without plugging it in and recharging so it's name is a scam) is flat they have a small battery inside these units at a high cost and regular recharging, same as any setup.
As suggested the "power station" might be limited capacity to run the fridge. It does take a bigger surge of power to start a fridge motor again from stopped than when it is running. This might be too much for your battery unit to supply so it shuts down to save itself.
You would have to give us more details of the type and capacity of the power station and the fridge power rating to be more helpful. I see adds for those things with lots of items plugged in and think that they would not last long before being depleated running those items. Over hyped comes to my mind !

This is a problem I was warned about by a friend who knew I was about to buy a power station, so i pre-empted the problem and am now about to buy a100amp battery and box for the backof the Ute. It worked out the a 300w station would not supply the run time that I'm looking for.
Thanks for the input it really helped with my decision.

Sounds like the OP has had the question answered to their satisfaction. I just wanted to ask what the difference is between a battery box and a power station? There were several uses of the term "so-called" in the previous replies. My impression has been that they're essentially the same, but the power station has a few more smarts. Possibly because it can input power directly from sources like AC and solar. Is that it?
What I understand is a power station comes rated as 300w power supply with every low lithium power storage, subject to price but has an inverter builtin and is capable of charging off 12v 240v or solar.
A battery box set up is a normal battery in a box (home made or bought) with whatever connections you require, but you need to add a dcdc charger and inverter.
For me it's now a better financial option to run a box with a 100amp lithium battery as I already have an inverter.

Hi, that is probably a fair assessment. The power stations might have a few more handy smarts and usually have outlets for most things you have too but depends on what you pay really. The cheaper ones are not as good in any respect as the bigger very expensive ones.
Looking at the power ratings they use, the model above with 300Watts, comparing it to a 12V battery that is only roughly equal to 25Ahr at 12V; { 300W/12V = 25 AHr capacity }. That is not enough to run anything for much useful time. Just forget all those pictures of welders or cookers or high power things, even a fridge at 5A only gets 5 hours. So do not be misled by the BS. It would keep your phone going and a small light for a couple of days IMHO.
I use a Renogy 200 power station, has been great in the caravan to have power to move around and for small 240v devices definitely worth it when off grid
yes very correct, only decent size lithium batteries are good for fridges, but these power stations do provide portable power for a lot of lower powered devices with many different connections , very handy piece of kit.
