The final cut of TMC Podcast #29 is available now with topics time-stamped. We discussed the Tesla Cybertruck's expected 1 MW Ultra-Fast Charging capability, the Tesla Semi Delivery Event, the coming Model 3 refresh (project "Highland"), and more. You can watch it now on YouTube.
I let it run for an hour today and gained 1%. As for MPG that is what i came up with as well 10-15 MPG actual, 18 MPG is theoretically possible.
I was struggling with how to store and transport spare fuel for the genny and didn't want a messy smelly gas can in my car, not to mention gas in a container can easily go bad and needs additives to be stored. Propane lasts the life of the tank if left alone. (12 years on nice tanks) 5 years on used recertified tanks. That being said some tanks are still in circulation since the 90s so i bet you can get much more than 12 years off a new tank.
As for time to charge. It would be the same as plugging in to a normal 5-15 outlet. This genny can output 15a @ 120v so I could charge a bit quicker if I get the 5-20 adapter and set the charge rate to 15a on the screen
I have a Honda 2000i with a Hutch Mtn propane conversion. I’ve test charged my 3 at 12 amps for about an hour. It charges at 4mph just like a normal wall outlet. You do have to make or buy a plug to bond the ground on the generator or the UMC will refuse to charge at all. It would have to be a pretty dire emergency to have to rely on this to get around in your Tesla.
