I know the title sounds crazy, like why would you do that? Well last month we had an extended power outage due to a storm and I ran my whole house for several days off my Harbor Freight 8750kw gas generator. Its a cheap one, paid about $500 on sale, so I know its not an inverter or sine wave generator. I have seen so many YouTube videos claiming you can't charge a Tesla unless you use an expensive generator with an inverter.
So just to test that theory I decided to try charging my Tesla using my Tesla mobile charger that came with the car. At first I tried 120V 12A and I was surprised that it worked just fine! Left it charging for about 30 minutes. Next I got brave and tried 240V 32A. The generator is only rated at 28A and I was powering a number of things in the house at the time. To my surprise my Model 3 started charging and slowly ramped up to 16A and held there. It seemed to be fine charging until I disconnected after about 10 minutes.
So the expensive inverter sine wave generator theory is dis-proven. Seems you just need a steady power source. Did Tesla do something in software to improve charging and make it more tolerant of less than ideal power sources?
Has anyone else had any longer term experience using a gas generator?
