Not many threads I could find on this so hopefully this will be helpful to others. I believe the Tesla manual says it doesn't like or not to use power inverters, but I need to charge my laptop on the go so I started looking around. I just finished testing a few 12V-24V inverters because my 12V wasn't working correctly and randomly on my new '22 MY. There is no specific 16V inverter, so I purchased 3 different 12V-24V inverters which also took into account any voltage variation. I tested both the front/rear 16V outlets getting anywhere from 14.2V - 15.7V depending on the battery voltage.
The 3rd in the list below was the best w/120W of continuous power, had a separate power cord, and had cig-lighter extensions. The cig-lighter extension on the unit measured the same voltage as the battery which meant variable voltage and convenient. I connected my 12V 120W tire inflator to the cig-lighter extension and ran it for 5 minutes without a problem. I also charged up my laptop using an 87W MBP power adapter and it also worked great. The unit had a slight buzzing to it but so did my 12V inverter.
Tested all 3 below all of which worked and was able to piggy back my 12V inverter.
I kept the 3rd since it was the most useful.

Pic of the one 1 kept which has 3 outlets (1 grounded), multiple USB charging ports, and 2 cig-lighter extensions.

(looks huge, though). Powered accessories are going to be a learning curve for a lot of us with the newer generation of 15.5v Teslas. My current plan for a carry-along air compressor is a battery powered unit, those that look like power drills. If I absolutely need air, I won't risk something being fried by too much juice.
