There is a converter that takes power from the high voltage battery to charge/maintain the 12v battery; there is no generator.
Perfect, then there isn’t any need for a mobil generator when working in the field.The 12V battery is charged as needed from the main car battery even if the "engine is not running". This was added in a recent update since the early ID.3 were having dead 12v batteries too often when just sitting parked, due to a low drain but always on portion of the electronics. You should be safe to run your inverter.

Has anybody successfully used a car refrigerator with their ID.4? With our Hyundai Santa Fe Hybrid our car refrigerator really sucks the voltage from the 12v battery to point of being unusable (even when driving). Luckily our Limited trim has the 120v inverter plug which we will use for the fridge.... and it seem you can move a fuse to make the rear 12v outlet 'always on'.

Thanks. Just realized this was an ID3 thread but I'm guessing the ID4 will be the same. We have a 26 quart fridge and a huge 100 quart model. Both use compressors like yours. I'm going to install a bluetooth battery module on the 12v battery of the ID4 so I can keep an eye on it. The 12v battery in our hybrid only charges when the car is at idle. So I have it set to power off after 30 minutes so the 12v can charge when my wife returns from work and I put it on a tender every weekend. I hope that is not necessary with the ID4. I have read the Hyundai Ioniq 5 has the same 12v problem as our hybrid. It's like the battery charge algorithm is for a lithium battery even though they are AGM batteries.It works great with my fridge/freezer linked here. I don't leave it plugged in much when not driving, to avoid repeated cycling of the 12v which will harm it. It only draws 45 watts and can be set cold enough to keep frozen the entire 53 quarts of contents. It has a real compressor like in home fridges, which makes it much better than the more common and cheaper piezoelectric types.
Not sure if it still needs to be plugged in. Namely, I have had some 12 V battery warnings and "charge by driving" notifications after the car has been parked overnight in cold without charging. There's also a power save mode that will kick in on too low 12 V and it will shut down 4G, Kessy etc. This has happened with SW 2.4. However, SW 3.0 seems to behave better.The 12V battery is charged as needed from the main car battery even if the "engine is not running".
