Comparing the 2 outlets recommended by Tesla with the sub $10 big box model as well as the one I think you should buy
1. Hubbell 9450a
2. Bryant 9450fr
3. Cooper 5754n
4. Leviton 279-S00
The Hubbell and Bryant are far and away the superior product here and since Hubbell owns Bryant and these outlets were recently redesigned you can see from the pictures that there is almost no difference in these products, looks to me that it may only be the size of the allen screws and that is it.
The main reasons these are superior are, Lug boxes with V shape and the heavy copper strap that when tightening gathers the wire together instead of separating them and the fact that these both use 75 in. pounds of torque instead of 25 like the other 2, they both handle higher temperatures and have heavier one pc. power and ground contacts, there is no comparison to any other 14-50 Nema outlets.
The Cooper is good and much heavier than the Leviton but still falls short of the Hubbell and Bryant.
The Leviton unit is like a toy compared to others as it's really poorly built with smaller contacts, screw terminals without a pinch lock causing the wire to be stressed when tightened, just a cheap design.

Best part is now you don't have to pay $90 to $100 or more for the Hubbel as you can get the Bryant for $21
