I have a Model X and love it. I think its the best Daily Driver you can buy (but Gf is driving it LOL). My other car is a BMW M3, I leased it a couple years ago and now the lease is coming to an end. To replace it, I want a practical cheap EV (Bolt, Volt, I3, Leaf) doesn't really matter. It will be just a car i can take from point a to point b. Something to drive while i wait a couple years for a roadster. It has to be a lease, this eliminates Model 3. After driving a Tesla X75 and feeling the immediate power delivery, (turbo M3 cant match it) I want roadster.

So, I charge my Model X with a Nema 10-30 dryer outlet. I have a Gas buddy that splits dryer and the UMC (works great recommend it). I want to know if there is an adapter that i can connect to a a UMC and charge other Ev's. I saw a video from old thread of an I3 charging and some Kikstarter project.

This community is amazing and i would love any good solutions. Really would like to get an Ev as a lease.

I don't know if there's a UMC to other adapter. Since the MX came with an assortment of adapter; I would think it would be easier to get a 10-30 J1772 to fit the new car, and then use the supplied Tesla adapter to plug into the X. It's probably the quickest and easiest way and your new car might even come with a J1772 cord already.

Derek Thank you. This is what I was looking for. It’s not that expensive and I don’t mind trying it out.

Yinn I agree it might have been easier to go the other way and charge the Tesla with the provided adapter, but I already have everything in place. Don’t want to change things if I can avoid it.

To change Model X I am using Tesla 10-30 Adapter to physically limit to 30 amp. Will this adapter work the same way on other ev. Will it be automatically limited to 30amps

Yes. The UMC communicates the limit to your Tesla using standard J1772 protocols and it would give any other car the same 30A max pilot signal and they should understand it.

I actually don't think there are any non-Tesla EVs in the U.S. that can do more than 30A on an AC source right now, though.

Great info.
I was thinking i3 because the dealer is giving me 4000$ off the next BMW if I return lease early. Offer should be for any BMW not just the new M3 lease. But will double check.
Unfortunately dealer is in LA area and I am in Bay Area 300 miles away. Not sure how long it will take me to drive back. Maybe they can ship it.
