I can't charge my Cybertruck from the 30A TT-30 outlet on my 120Vac generator (Westinghouse iGen4500DF). I'm able to do so on my Model Y with the same setup. I use a TT-30 to 14-50 adapter with my Tesla Mobile Charger. Everything looks good until it starts pulling amps and quickly stops charging with the green LED on the NACS port changing to red and a charging stopped message on CT's display. I have the ground wire (green) tied to neutral (white). Has anyone experienced this? Will CT not charge from the 30A 120Vac outlets that you find on generators and at campgrounds?

There's a long thread on TMC about this subject. The TL;DR on the Mobile Connector is:
- it checks for ground, and
- really wants an inverter-generator (clean sinewave) power

Since it starts charging, I'll assume the setup passed the ground test. I'm guessing it found the quality of the power to be distasteful.

There's something going on with my ability to charge my Cybertruck.

When we returned home from a camping trip yesterday, I attempted to charge the truck using the Level 2 240V 14-50 outlet in my garage, and just like on the return from an earlier camping trip, the truck wouldn’t charge. No errors were thrown, but the battery was not getting any current.

I connect the L1 120V charger adapter and it charged at 12A as usual. An hour later I tried again to charge from the 240V 14-50 outlet and everything worked. This is the same behavior I experienced before.

It appears that after Supercharging the truck, the 240Vac AC charger won’t work on my CT until I first charge with the 120Vac Level 1 charger. So weird!

I think not being able to charge the CT from the 30A 120Vac outlet on the generator when I was camping the other day is somehow related. Today, I had no trouble charging the CT from my generator's 30A outlet at 24A (2.9 kW).

The question now is: Is this a problem peculiar to my CT, or a bug in the charger software?
