Which NEMA 6-50 Adapter?

I will travel and stay somewhere where there's a NEMA 6-50 plug. My understanding is that TESLA doesn't sell the 6-50 to 14-50 adapters anymore, so I have to find one. I did check with my local Tesla Serive Center (through my Delivery Specialist) and they don't have any. The two that I've seen mentioned in the TM forums in some way are:

NEMA 6-50P to 14-50R EV Adapter, 50A, 250V | EV Adapters for $75
NEMA 14-50R to 6-50P Adapter for $55

My questions are:

  1. Which one do you recommend? Anyone out there with bad experiences with either one?
  2. Is it worth to go with #1 which is more expensive (+$20)? The cable has a different gauge, needed?

I would probably go for #2 as both the plug and the receptacle are injection-molded, shatter-resistant, probably more water-resistant and also smaller. For such a short length the slightly smaller wire gauge doesn't matter much, other than being lighter though EVSEupgrade can offer extra length.
I actually like #1 better. The fact that you can open the connector and inspect it. You could also use the parts and change out the plug end if you decide it isn't what you wanted. I see #1 as more flexible and recyclable than #2. It also has a heavier awg of wire.

I have#1, but would have bought#2 had I known about it. #1 is fine, but it's stiff, heavy and a bit of a pain to store in the car. The lighter gage wire on #2 won't make any practical difference.

I just built my own with $40 of parts. See: http://cosmacelf.net/Home Made Adapters.pdf

But if I had to do it again, I'd just buy #2. Working with 6 gauge wire on the plug and socket was a royal PIA.
