I want to buy a 33 quart 12v fridge (cooler) and a Bluetti AC70P . Can I plug the AC70P into the 12v outlet on my car and plug the 12v fridge into the AC70P and expect the AC70P to charge while the car is running and at the same time power the fridge?

You can connect to the device in this way.
However, the cigarette lighter output of the AC70P is a total of 120W, and it may not be sufficient to power the cooler.
A small fridge i.e. Engel draws approx 38W, other normal compressor fridges draw around 80-90W. If you run the fridge from the 12V socket and plug the AC70 into the car when driving, it will work.
If the AC70 is at 100% to start, it will remain at 100% with engine on. Overnight, the fridge will run off the AC70 and should last the night. However, in winter, no problem, in summer with hot nights, borderline.
Fridges cycle at around a 1/3 of the time at 25C (77F), in ambient of 40C (104F they are on all of the time. This is how to calculate run time which will vary in different ambient temps.
If you run the fridge from the inverter on AC volts, run time will be much less/
Yes, that will work fine as long as your AC70P is not very low on battery power and you are expecting a fast recharge.
Thanks everyone for the info.
