AC WORKSElectric Vehicle Charging Adapter for Tesla Use (14-30 4-Prong Dryer to Tesla)

This works great for adapting from my NEMA 14-30R receptacle to our Grizzl-E charger which has a NEMA 14-50P plug. It fits securely, has a thick, well-made connector, and has given no issues so far.

Beefcake

We carry this in our RV and use it when we're in a friend's driveway and they have an accessible 30A 240V dryer/welding outlet. You can add another adapter to convert the female end to a standard 30-amp RV plug (which just ignores one of the two 120V hot lines) if you have a 30 amp RV or use it directly with a 50 amp trailer. In a 50 amp trailer, which is normally plugged into 50A 240V (two 50A 120V hot lines serving different parts of your RV), you'll get 30A 240V (two 30A 120V hot lines) so it's not much of a difference from a full 50A hookup. If you have two air conditioners, you might just have to momentarily turn off the one that shares the line with your microwave to run the microwave, but otherwise you won't experience much of an inconvenience. You can look at your RV's fuse panel to determine which appliances are on which of the two hot lines.

This was exactly what I needed for my house. I have a dryer plug that I wasn't using since my dryer is gas. The dryer outlet is using a 30A breaker. When I used the tesla Universal Mobile Connector (UMC) using the NEMA 14-30 charging adapter, I only got about 17-18 mi/hr of charge and was only getting 24A. When using this adapter, this allowed me to use the NEMA 14-50 adapter, but here is the catch. The car thinks it can pull up to 40A and the breaker tripped. You need to adjust the amperage on the tesla charging screen to 30A (or whatever your breaker maximum is) and that did the trick. I was able to charge about 28 mi/hr without any issuers. Hopefully this helps those who are trying to charge their Teslas at home using the dryer outlet.

It worked to connect a male 50A RV plug to a female 4 prong 240v 30A dryer connection. It is expensive because it is sold to people that have a Tesla. It does not magically turn two 30 amp legs into two 50 amp legs, but it sure beats a single 15 amp leg wall socket.

Perfect. Should have bought sooner. Went from charging 5 miles an hour to 23 miles per hour for $50!

Visited my out-of-state family for a couple weeks, and this adapter worked perfectly to connect my sister's dryer outlet to my Tesla NEMA 14-50 charging connector to charge my Tesla Model 3. Just be sure to reduce the draw to 25 amps on the Tesla touchscreen to not overload the connector and circuit.
