So I tried out my new adapter with our '22 MYLR tonight at a 350kW EA station. SOC was 55%, outside temp was about 60°F, but I drove for about 15 minutes with a nearby SC as my nav destination to get some preconditioning. I have an EA account but after futzing with it for about 5 minutes I could not get the stupid station to accept it from my phone. I had to use a physical credit card. Definitely a PITA to use compared to SCs. Worse, I only got at most 33kW which is very low for 55% SOC. (I would have expected at least double that from any SC.) I only charged for about 2 minutes, so maybe it would have sped up.
Nonetheless, I wish I had this when I went through ABQ in late March (like 3 days before the new SC opened there), because the lines at the old 6-stall SC were 4-5 deep, while a nearby EA station with at least a dozen CCS plugs was not even 50% full. (I ended up using my old CHAdeMO adapter on the one compatible—but ostensibly broken—EA stall and got 50kW, but it was still quite a bit faster than waiting in that line at the SC.)
I hope to try this on our '22 MSLR in the next few days. That's the car I really want it to work well with, as that's our new road trip car.
