Is the NEMA 14-50 high power wall charger still available through Tesla? I can't seem to find it on their site. We are moving and I would like to go with this setup if possible. Thanks in advance.

In need of a shrinking gun to zap a plaid with.
Yeah, they are up to version 3 of the HPWC. I’ll try to locate a link.
Wall Connector
Oh you mean one that plugs into 14-50 plug. EeeSh I dunno about that.

If you mean the Gen 2 NEMA 14-50 Adapter, yes it is available here: Gen 2 NEMA Adapters
Your wording is a bit ambiguous since there is also the High Power Wall Connector which is a separate product available here: Wall Connector
Although both a currently available, they often run out of stock and then restock after a few days/weeks so order as soon as you can.
Thanks! There used to be an actual HPWC that was wall-mounted and could be plugged into a NEMA 14-50 outlet. I don't see that item anymore.

It was a rare, short run, that I think were originally destined for Canada.
I like your set-up. I was concerned with the wire getting pulled out from the bottom accidentally but I notice you have a locknut on top and bottom. I take it you can find that in the electrical section at HD?This is what I did. Home Depot sells the dryer whip - it was $25 I think.
Thanks.

I sent this to another member regarding the same subject of adding a plug to a HPWC. Please keep in mind this info is for a Gen2 HPWC. Same idea applies to a Gen3 HPWC, just the wiring will look different and a Gen3 doesn't use dip/rotary switches to set current limits.
You'll only need 2 parts; a replacement dryer/range cord and a cable gland.
For the replacement dryer/range cord, just make sure it is rated at 50A and not 30A. Here is an example from Best Buy. (Model:5305510956 SKU:3921073) But you could get them at places like Home Depot.

For the cable gland, you'll need one with a 1" thread and capable of passing through a 0.75" cable. Here is an example from Grainger. (Item # 2DPD9 Mfr. Model # SEC100BA)

To install the cable, you'll need to cut off the ring terminals and strip some of the insulation off the end so that the wire goes into the main terminal blocks in the HPWC.

Typically, the black and red wires are hot (interchangeable), white is neutral (not used; end should be covered), and green is ground. However, it is always a good idea to double check with a continuity tester. Also, make sure to run all the parts of the cable gland onto the cable before routing the cable into the HPWC.
Here is what the inside of the HPWC looks like. (Borrowed the image)

Last, but not least, make sure to set the DIP switches and rotary switch are set to the appropriate settings for a 50A circuit.

Those only appeared on the tesla store site twice I think, and sold out both times in less than a day. In another thread about them someone said that they'd heard that these wouldn't be back. I managed to get one, it works well, but agreed you could easily make your own if you're so inclined.
If you want the plug-in Wall Connector, you can check on eBay. Occasionally someone sells one there. As an electrical engineer, I'll say I like Adam3's solution, IF you know what you're doing. Whether that's in code or not in your locality is something you'll have to find out for yourself. If you install something that's not in code and your house burns down, your insurance probably won't pay.
And there are non-Tesla solutions, such as ChargePoint Home Flex, that give you full charging speed with a plug-in charger but require that you use your J1772 adapter.

I have a same set up as this.. Just buy the 14-50 dryer wire and plug the 3 wires into the wall connector. Very simple..
The NEMA 14-50 HPWC was replaced by the Corded Mobile Connector: Corded Mobile Connector. Like the 14-50 HPWC, it supports the full 40A charging rate a NEMA 14-50 is capable of (the regular Mobile Connector only supports 32A).
Get it while you can - they never stay in stock for long, but they are as I'm writing this!
Edit: you can also get a Gen 2 Cable Organizer to go along with your Corded Mobile Connector and give it wall mounting similar to the HPWC.

The speed will depend on the circuit breaker amperage. If you are using a 50amp breaker the corded wall connector will provide up to 40 amps. The Gen 2 mobile connector can provide a max of 32 amps even on a 50 amp circuit. The Gen 1 mobile connector can provide up to 40 amps on a 50 amp circuit.

The dryer cord is only good for 30A. Get a stove cord.

40 amps of charging a Model Y using a High Power Wall Connector will get you about 33 - 34 miles/hour while 32 amps using a Gen 2 Mobile Connector will get you about 29 - 30 miles/hour.
