Spare UMC Availability

Good points - I have 40A in my garage so I could use the HPWC dialed down to 40A

Depending on the actual wire that was installed for the 14-50, you may be able to put in a 60 or 70 Amp breaker with the HPWC and charge at 48 or 56 Amps. Another 20-40% in charge rate never hurts.

6/3 wire but I only have a single charger in my Tesla

Depending on the type of insulation on the 6/3, code should allow a 60 or 70 Amp breaker. Although it won't help you with a single charger, you may have friends stopping by with dual chargers or your next Tesla may be able to absorb more than 40 Amps. A new breaker only costs a few dozen dollars, ramp it up for friends and the future.

Good Luck!

I looked at a bunch of options a year ago and came to the conclusion that the HPWC is the cleanest, safest solution for my garage. No adapters to mess with and only one mechanical connection (at the car itself). I dislike the UMC because it has 3 mechanical connections (wall plug, adapter and car) plus the UMC module itself is on the cable. More points for stress and potentially failure. The experience with the 14-50 adapter recall kind of makes my point here. Sure the HPWC costs more but so does the car.

This.

I sprung for an HPWC and even though 95+% of my garage charging is around 40 amps, I'm happy to have the cleaner, neater HPWC and leave the UMC in the trunk. Plus, if I need a faster turnaround at home, which happens sometimes, I can dial the HPWC up to 80 amps.

Geeze, rockster, except for the spoiler, we have exactly the same car.

Enquired about just purchasing a UMC yesterday at the Scottsdale, AZ service center and was told it was not available. I would need to buy the entire package (spare adapters & bag) for $650.

40 amps - 9.08k ohms

24 amps - 33.16k ohms

16 amps - 75k ohms

12 amps - 140k ohms

I'm adding this datapoint to every thread where I see this table -

32 amps - 20k ohms (measured from a Canadian 14-50 adapter)

The charging accessories have been re-priced after being labled as Out of Stock. The Bundle is now $550, Corded Mobile Connector $520 and both cable lengths of Wall Connector are $500. Everything above is now in stock on the web site.
