As a Tesla EV owner my first…
As a Tesla EV owner my first thought was why run the generator to charge the battery all the way to 100 percent? I get the fact that he wanted to see how long it would take but at the same time the computer in the vehicle does the math for you and gives you a time estimate. It would be different if this individual were actually taking the Cybertruck to a location so remote a full charge was needed but that wasn't in the story. As a proof of concept; that you can use a gas generator in a pinch to add enough charge to get to the next charger, isn't anything new either. Charging to 100 percent on a generator is like running out of gas in your ICE truck then lugging 20 gallons of gas to fill the entire tank. A smaller, cheaper (and likely quieter) generator would get you to a nearby charger in most places with a lot less effort.
