How can you visually tell the difference between a gen1 and gen2 HPWC?
Without it being hooked up, can you still tell the difference?
My Gen 2 TESLA HPWC letters don't glow green?
Not sure if it is 100% reliable....but.... my generation 1 Charger had a separate wall mount hanger for the cord and plug. Both of my generation 2 chargers have a place in the right side of the charger where the plug attaches when not plugged in.
Correct. I was thinking UMC. Sorry about the confusion. I have a Gen 2 UMC permanently mounted on our wall.
The Reset button is on the left on the Gen 2 and on the right on the Gen 1. Internally, of course, many differences (DIP vs Rotary configuration...).
And as for 'glowing green', there is a moving green 'bar' when charging. Steady when connected and all is well.
That's Gen 2, of course:
Here's the Gen 1 manual:

GEN 1 .......... GEN 2
Thanks to all!!
Is there a difference in the charge speed if you have a gen 1 or gen 2?
Does the Gen 1 cable deliver higher power because its thicker?
No, they can both go to 80A. Your charge speed will depend on what they are actually connected to (and set for), and what your car's on-board charger limits are (40A, 48A, 72A, 80A).
No directly what you asked, but the functional differences between gen1 and gen2 are that gen2 can automatically power balance with other gen2 HPWC's, and get2 doesn't have issues charging 2018+ cars, gen1 does have weird intermittent issues charging newer Tesla cars (the issues seems to start around the same time as MCU2 was released - the solution for people who upgrade their Teslas since 2018 is to just swap gen1 HPWC with gen2).
