Can I Charge via Portable Generator?

Can I Charge via Portable Generator?

Hello folks, I am thinking about getting one of these machines here http://generatorist.com/best-5500-watt-portable-generators and I was wondering whether these machines can be used to charge Tesla. If not one of these machines, what products should I look at?

Is this safe to do? Can I charge Tesla via any other portable device? I don't want to break something.

Thanks for any input.

Theoretically possible, you’d have to ground the neutral connector otherwise the UMC will show an earth fault and no charging will happen.
Will only give single figures of extra range for every hour of generator running.

Tried it with two 230V, 1000 W and 1700 W rated generators (continuous power output). I had to ground the "neutral connector" (can be either one) to have the UMC display a green light. The latter Generator worked with 7A setting while it cut out at the 8A setting. The first generator stopped immediately as unfortunately 5A is the lowest setting you can set in a Tesla (had a peak performance of 1200W, but that didn't help).

Also watch out that the generator has a "sine wave/ inverter" output as the usual "block-wave"(?) output might not work.

This one worked for me: https://www.zipper-maschinen.at/DE/Stromerzeuger-4361

Thank you for the tips guys, keep them coming.

Why do this? It’s slow and very dirty.

And very SLOW!

What is the point of having a clean air vehicle and power it with an ICE machine and lost yet even more efficiency in the process?

Oh and WAY more expensive! S75RedRidingHood +. 1

Well, if for whatever reason you’re stuck out by the lake cabin with low charge but plenty of time and 16 100W solar panels and a sine wave inverter, you can fish for a couple of days while you charge from the sun and get enough range to get you back to civilisation.

To Anthony's question...Zombie Apocolypse...
To the OP... I put jumpers on an ICE with 450k miles, original alternator, connected to a 1kw pure sine wave inverter, and was able to pull 8 amps, about one mile of range per hour.

Here in SoCal, despite what might surmise from the last election results, no Zombies yet, but overdue for a massive earthquake..

As the members mentioned above - its' quite slow, but if this is the only option for you, feel free to check for portable generators here https://generatoron.org/best-portable-generator/
