Here is their Kickstarter page: Ev Charger Level 2 - Quick Charge Power
Looks to be about a six month wait.

A group buy for the local clubs (VEVA and TOC of BC) underway. I sent an email to see if this offer can be extended to TMC, how it fits into kickstarter and ETA.
Only if Tesla owners feel overly entitled. QCP is very clear that users should get permission to use any Tesla charging point that they use. If the owner/operator of the HPWC is OK with it, then Tesla drivers have no more right to unplug a J1772 EV while charging than they would a Tesla.

80A home charger, HPWC, High Power Wall Charger, Tesla says "Availability: In Stock", for $999, and has all the claimed features mentioned in messages above of the current Tesla High Power Wall Connector (load sharing up to 100amp circuit 80 amp supply to vehicles (max), etc.). Am I right that this is essentially just a $550 Tesla High Power Wall Connector with a J1772 plug fitted on the end? That seems like someone could do it for the cost of a Tesla HPWC + J1772 plug properly attached. I sent a query to them asking if they got separate UL listing for this new configuration; that UL listing would make the extra $250 or so worth it.

The QuickChargePower ad seems a little sleazy to me. For any vehicle other than a Tesla, the 80A charging station is no faster than a 32A charging station. ClipperCreek sells those for about half the cost (HCS-40, $565). If you have a Model S/X or Roadster, then you're better off with the appropriate Tesla connector. I suppose a hotel could use the J-HPWC to offer charging for all EVs and maximum charge rate for Tesla owners, but personally at a hotel I'd rather have two 32A charging stations than one 80A station. The 80A chargers are nice at restaurants and the like for Roadsters that can charge at 70A and can't use the Supercharger network.
I personally appreciate every such station that's out there, but it's a pretty niche market.

You don't have to use a Jwall with an 80 amp circuit any more than you have to use a HPWC with an 80 amp circuit. For situations where you may have only one 50 amp circuit available, but two EVs to charge, I think this is a good solution. It's even better that you can charge one Tesla vehicle with a HPWC and one non-Tesla vehicle with a Jwall on that shared circuit. The alternative, charging both cars with only 20 amps (4.8kW) is clearly an inferior solution. Also, as battery packs get bigger, I expect more automakers will move beyond 32 amps for their on-board chargers.
I personally appreciate that all these niche products exist to solve challenges in people's unique situations.

I guess Tesla must be "sleazy", too, since they offer 80 amp equipment, and most Tesla cars are 40 or 48 amp capable.

You are right Tony, calling it "a little sleazy" was overly harsh. My only objection was to this sentence which could be misleading to people who don't understand that charge rate is limited by both the car and the station.
J-Wall provides the absolute fastest way to charge ANY vehicle at home with J1772 when the unit is installed with a 100 amp circuit.
I apologize for not choosing my words more carefully. I respect your contribution and commitment to the EV community.

You don't need to apologize too much. "sleazy" was a bit harsh, but "a little misleading" would be pretty accurate. @TonyWilliams went through that huge list to show about 28 other kinds of EVs, and it proved your point exactly. Every single EV that does not use the Tesla onboard charger can only use 32A or less--exactly as you stated.

Our biggest customers for J-Wall are owners of:
1) Tesla powered 2012-2014 Toyota RAV4 EV at 40 amps
2) Tesla powered 2014-newer Mercedes B-Class ED at 40 amps
3) Tesla owners with a 40-80 amp onboard charger that also have a LEAF, i3, Soul EV, etc.
4) Commercial vehciles at 80 amps
5) Folks with a Volt, LEAF, etc, now who plan to have a "real" car someday
6) Folks who want to charge 2-4 cars at once with limited available electrical power (for instance, 4 units on one 50 amp breaker)
7) Commercial venues like motels, auto dealers, etc
8) Professional installation companies
None, to my knowledge, were confused about what they wanted or what the unit might do for them. I freely answer questions and provide the very same data you find proves something else entirely.
Anyhoo, I don't find the wording to the ad misleading at all, nor do we want to be misleading. I've spent a good deal of my EV advocate life fighting against wrongs in the EV world. So, what do you think it should say?
Were those "specs" for Model 3 published somewhere already? Or are you just extrapolating/guessing based on current production Tesla vehicles?

Here's a statement that is more clear and explanatory, and gives context for the list of vehicle charge limits later on the page.
When installed with a 100-amp circuit, J-Wall provides the maximum amperage allowed by the J1772 standard (80A) to support full-speed Level 2 charging for any vehicle. The actual charge rate will depend on line voltage and the vehicle's on-board charging equipment.
Using "Level 2" is a little nerdy, but I notice the page uses "L2" in the first sentence on the page.
I intentionally left out any mention of "at home" because there are good reasons to avoid high amperage for overnight charging at home, but that's a topic for a different thread.
I usually say the Gubment needs to stay out of things, but ever we needed federal regulations and oversight it's on standards that allow business and innovation to flourish. Government should help select a standard and reward it's implementation. Charge stations should not be proprietary and need to accommodate all known variations under fair market and even disability access.
Engineering associations need to establish standards. The government is terrible at it. Political favors and engineering necessity do not mix.
Generally speaking you're right. But look what happened with SAE J1772. It sucks compared to Tesla's proprietary coupler. I suspect Tesla's design will eventually become the standard because it's safer (handles more amps), more compact, and dual purpose (both AC and DC).
