Exactly what I wanted. Rivian R1T
Had a RV30 plug in the garage from an old welder I used to use. This adapter works wonderfully with the R1T portable charger. 30amp gets me 6mi/hr of charge. Not fast, but that's not the adapters fault. See graph for details. Great adapter!

5.0 out of 5 stars Bought for Tesla 30amp connector
Reviewed in the United States on October 8, 2023
Verified Purchase
So, first, this definitely works to convert the 14-50 to a 30amp. It charged my Tesla. However, the Tesla was allowing this setup to pull up to 32amps off the 120 setup. Not good news. I ended up almost catching my house on fire due to the plug on my house getting so hot it melted and was smoking everywhere. Moral of the story is, if you’re buying for this reason, be very very cautious. The part itself gets 5 stars because it works fantastic. None of my issues were caused by the part itself, but the end result was me being without a 30amp connection and almost burning my house down. Ended up hiring an electrician to come out and putting a 50amp and fix the 30amp. So 5 star for the part, just be careful

I got this for camping road trips with my Tesla Model 3 when there isn't a 50 amp charging spot at campgrounds or RV parks. Only used it a few times since buying it a year ago, but so far so good!

5.0 out of 5 stars Works!
Reviewed in the United States on August 11, 2021

This product is intended to be used with the tesla mobile connector's 50A plug. Newer Tesla's may not have this included and if I were you, I would getting one.

This adapter is a little weird, since a 30A RV hookup is 120V, and the 50A plug is for 240V, but this setup works just fine, and the car can detect the voltage. What it doesn't do is set max current.

I would caution users to manually reduce the amps in your charge setting before plugging in your charger. 24A max.

Additionally, some RV parks are quite old, and have old electrical infrastructure. You should check with someone first that there is no danger of popping a mid-level breaker during a high use period (hot day), leaving folks without power.

Reviewed in the United States on October 17, 2023

I usually drive my Tesla Model Y for road trips and been staying at hotels and using Superchargers which can be costly.

Decided to try something different by staying overnight at a RV campsite instead. The adapter does work but questionable. Initially, it was charging around 11 miles per hour then died down to 5 miles per hour. Was expecting to charge around 20 miles per hour?

Plugged this adapter into the TT-30 receptacle at the Ontario Provincial Park and used the mobile connector outfitted with the 14-50 adapter. Was able to get 6-7% worth of charge per hour on my M3 SR+. Tried to use cheaper, generic RV TT-30 to 14-50 RV adapter to no avail, before I knew to buy an adapter specifically for EV charging like this one. Would buy again!
