So the NEMA 6 series doesn't have a neutral line, which you shouldn't need anyways but I can't confirm the BMW fast charger doesn't use it. Otherwise seems fine

Will a nema 6-50P to 14-50R adapter work?
I know BMW offers an official nema 6-50 adapter (photo is from BMW Group ) for the flex fast charger, but I was wondering if I could buy a 6-50P to 14-50R adapter to use the included 14-50P adapter that comes with the flex fast charger?

Seems like the BMW fast charger is neutral agnostic. Unless those adapters shown above are a lot smarter than they look, two of the three shown have no neutral. The simple adapter @PAi440 described should work. I certainly hope so, as I have a travel bag filled with adapters and extension cords that are intended for 240V use with no neutral.So the NEMA 6 series doesn't have a neutral line, which you shouldn't need anyways but I can't confirm the BMW fast charger doesn't use it.

That's a question for an electrician. The two plugs don't have the same number of prongs, which doesn't make it impossible, but why plug an adapter into an adapter if you don't need to? Just sounds like a bad idea, even if the non-BMW thing is cheaper.
Holy $#!+!!! $213 for a few inches of cable with plug ends? Now I understand why you're asking.
Why not change the outlet in question to a 14-50?

That’s what I was thinking. The official adapter from BMW that I’ve shown in my post costs over $200. Bought an adapter from jungle book for $24. I’ll let you know if it works.

I have a replacement 14-50 outlet but it kinda feels dirty not using a neutral wire and the cost to run a new line to my garage would be more than the $208 adapter even if I do the work myself, which I have done in the past. I just don’t see why it would need a neutral wire in the first place. I bought an adapter for $24. I’ll let you know if I burn down my house, or maybe I won’t (Doh!).That's a question for an electrician.

Installing a NEMA 14-50 outlet without a neutral would be a Code violation - the receptacle presents a neutral and some plug in devices need it. That said, I don't think the Flexible Fast Charger ( or other plugin charger) cares or knows if the neutral is present, so would probably work. Best to hard wire or use a NEMA 6-50 receptacle if no neutral is present.I have a replacement 14-50 outlet but it kinda feels dirty not using a neutral wire and the cost to run a new line to my garage would be more than the $208 adapter even if I do the work myself, which I have done in the past.

Seems like the ground on a 3-prong plug performs as both neutral and ground?
Nah. Ground is ground. Yes, they both have the same potential and are (often) on the same block on the panel. If the 240V equipment needs a 120V supply for something, the circuit must have a neutral. AFAIK, many EV chargers designed for a 14-50 plug simply have the neutral snipped off in the box. Not Code to use the bare ground as a neutral.Some quick reading…

I'm using a NEMA 6-20 (male) to 14-50 (female) adapter to connect to the included level 2 charger. It's working well, so a similar 6-50 to 14-50 should work too.
The idea of running 40 amps of current through an adapter in this situation is cringeworthy.
I'd personally begrudgingly spend the money for the BMW adapter, or buy a used EVSE with another adapter.

Almost every transition in an electrical system could be called an adapter. The breaker adapts the panel buss bar to the wire termination. The wire goes to a receptacle and that "adapts" the wires to a plug. Transitions to a brick, brick to J1772, J1772 to car, almost all 'adapt" or convert one form factor to another. Most are 'permanent" and don't move unless modified. My concern is any frequent connect/disconnect of a device. We frequently connect and disconnect the J1772 plug to the car without concern. IMHO, it's the design insertion cycles that matter. That's why I just don't "get" plug in chargers if plugged and unplugged on a regular basis. Higher current receptacles are simply not designed for repeated use (that's why a quality device is recommended). A properly rated adapter (in this case a 14-50 to 6-50), left in place, is (IMHO) minimally less reliable than just a plug in a receptacle. There are form factor, aesthetic and space considerations, sure. I would also cringe if an adapter and plug were exercised frequently, but I see no issue if simply left in place.The idea of running 40 amps of current through an adapter in this situation is cringeworthy.

I agree with everything you said. And its the idea of movement that worries me the most.A properly rated adapter (in this case a 14-50 to 6-50), left in place, is (IMHO) minimally less reliable than just a plug in a receptacle.
What adapter are they using though? I googled jungle book Nema 6-50 adapter and I'm clearly not finding it.
If I read the OP correctly, @PAi440 has a welding plug available. Any adapter from 6-50R to a 14 -50P would by definition, lose the neutral, but would work with the FFC 14-50 plug. (You've got to switch the R/P labels to get the correct "direction" to search for the adapter.) Could be something like this: Welder to BMW FFCWhat adapter are they using though?

BMW is selling a bespoke cable. One end goes into proprietary outlet on the Flexible Fast Charger, the other end into the 240 outlet. It replaces the stock cable, not as an addition to it.I agree with everything you said. And its the idea of movement that worries me the most.

Yep, just as shown in post #1 of this thread. Both "dongles" plug into the same "brick" - one has a neutral and one can't. That's why I'm comfortable believing the FFC doesn't require a neutral. I believe @PAi440 's question about an adapter is more about cost and suitability.BMW is selling a bespoke cable.
