Tesla offered a Roadster-to-J1772 adapter at one time, consisting of the two connectors with a bit over 3 feet of fat cable between them. It's not as convenient as the CAN-JR, which sits very nicely in the CAN holder by the passenger seat (that's what it's for, no?), but it works fine. I'm using one at home, always attached to the charging cord, with the CAN-JR remaining in the car so I don't have to mess with two plugs every time I charge.
Confirmed, that $69.99 adapter is for Model 3, etc, not Roadster. So my $159 one at 48 amps seems best (for me). Guessing the CAN that Henry Sharp has will go all the way to 70amp, but I'm not up for the price - CAN SR (Tesla 2 charging stations) is $795. But if that makes sense to you check out Henry's CAN SR on TMC. He's a TMC member by the way...
Followup on I-5 Tesla Chargers North of Seattle. Looks like there's four on the way to the Canadian border. Two on I-405, the Lynnwood I-5 and Burlington ones looks best. Got from the latest list of Tesla WA superchargers. Find Us | Tesla
Hoping they have Tesla 2 chargers too...
Planning a Deception Pass trip "recon" soon, since my son's Boy Scout troop 336 in Federal Way is planning an overnight at Cranberry Lake/Deception Pass State park Mar 26, 27.
Deception Pass
206 miles round trip. 9 hrs (206@60mph plus 4.5 hr charge)
Way points – one big ole boring drive up I-5, hwy 536 W, 20 W. An “artsy” La Conner side trip could be fun. It’s 11m W of Mt Vernon, connects to 20 W so sorta on the way to DP.
Supercharger Charge points to test out: – Lynnwood I5 (39), Bellevue I405 (23), Bothell I405 (34), Burlington I5 (88, 5 mile backtrack to hwy 20 for DP.
1772 Charge points 1 – Mt Vernon Burgermaster (82), 19 miles from Deception Pass. Hoping for a Full 70a, 220v like the Centralia one!
1772 Charge points 2 – Mt Vernon Skagit Transportation Center (82), 18 miles from Deception Pass.
1772 Charge points 3 – IBEW Local 191 (80), 23 miles from Deception Pass.

And my adapter doesn't have the Roadster plug. It has the J1772 so you can connect your "J1772 to Roadster" cable...
I guess I'm a little confused on your adapter. Clarifying... The cable Tesla offered has one end that connects to the car with its native Roadster plug, and the other end has a J1772 socket for connecting to a J1772 public charging cord. It does in 4 feet what the CAN-JR does in 6 inches.
Both CANs are rated for more than 70A continuous.
The aftermarket adapters (Lectron and the like) make me nervous. Almost every one I've seen in the field is rated for no more than 40A. There's nothing to prevent you from plugging a 70 or 80A charger into one of those and then charging a Roadster, or any other car that charges at high AC amps. It's a good way to start another Roadster fire.
You can say "I'll always remember to dial the amps down" until the day comes that you forget or the car resets to 70A, or somebody borrows your equipment who doesn't know. Some of those Tesla 2 to J1772 adapters don't even have a latch to hold the T-2 connector in the socket. I've been around long enough to witness 2 EV charging fires first hand. Fortunately they didn't involve CAN adapters but both garages routinely housed a Roadster. I've become much more conservative with charging safety in my old age.

It brightens my day to see @tjllew and others doing long trips in their Roadsters. My wife and I have many fond memories of Roadster adventures we had back before we got our Model 3. We never drove around the world like Rafael de Mestre did (alone) and Markus Doessegger did 4 years later with his Friend Matthias Aebi helping with navigation, but we did a couple trips that were over 2000 miles. A little searching of the old Roadster threads will bring up some great stories.
Thank you, tjllew for posting your trips because it renews memories and it's great to know that people are still doing this.

Ah, but @hcsharp’s CAN adapters are so elegant and compact. Worth every penny. And he stands behind them if anything goes wrong.
(and you won't need the J1772 cable if you have the CAN-SR. I'll go directly from the Tesla2 connector to the Roadster)
Thanks, I'll watch for that (make sure charge amps displayed are under 48). When I used mine I set the charging to the 70 amp max but my display said 48/48amps while charging. And then 25/48, etc. as the battery got full. Seems to be working perfectly. Hard to imagine the charging station was exactly 48amps, so sounds like the Roadster or adapter (or the Tesla2 charging station) knows to limit it to 48. And yes this is the only 48amp I can find. All others are 40 amps or less (including a 40 amp Lectron one in Amazon).
Yep! I have both CAN adapters (JR and SR), and both have had good use. Very well made.
Daisy-chaining adapters is generally a bad idea, especially when high currents are involved.
48A is quite common for a charging station. It was not a case of "the Roadster or adapter knows to limit to 48." It is the highest rate that you can charge a model 3 or Y (the vast majority of Teslas on the road) and that is the maximum rate of a new Tesla Wall Charger. The Roadster limited the current draw to 48A because that is was what was signaled from the wall charger. What would have happened if you had plugged into an older generation wall charger that could deliver 70A? Or a Clipper Creek TS-70 or 80? I've seen garage fires and other sh!t happen in these situations.
I'm not trying to discourage you or dampen your enthusiasm for faster charging on long trips. I'm actually impressed by your motivation to solve Roadster long-distance charging restraints. I'm only hoping to spread the message that some of the things you're doing are much more dangerous than you think, and requires a lot more caution than you currently imagine.
Yesterday's "Mini" road trip:
2022-02-12 Tacoma Waterfront, Puget Sound Steilacoom Beer Run
40 miles one way, 66 round-trip if you use the fast return route.
Way points – Ruston Way (19), Pt Defiance Park (3 or 8 if you do the 5 mile loop), Titlow Park (5), Chambers Bay (4), Sunnyside Beach Park (3), Steilacoom Tap Room (1).
For a fast return do Steilacoom Tap Room to I-5 (26 miles to home). Returns to Sunnyside, Chambers Bay then through (boring) central Tacoma to I-5.
Charge points – none needed (80 or 66 mi rt).
No good way to get a Steilcoom Tap Room photo with tjllew and me. So opted for the Titlow beach one (just before Titlow Park).

Good to know, thanks. I thought maybe the adapters or somewhere in the charging connection was a current sense.
Agree, need to know what you are doing. I'm an Electrical Engineer so I was (and always) look out for any overcurrent scenarios. I'll always set mine to 48 amps ahead of time and check that it is indeed charging at the 48a max or less before leaving it to charge. Think I'll also feel the adapter on my next charge to make sure it's not overheating (just in case the 48 rating was a bit optimistic).
Also of course no part of the "daisy chain" should exceed the rating on the adapters and cables. My 1772 is the OEM Tesla 70a one so no problem there.
Of course the ultimate fast-charge approach is to have the aftermarket Jdemo direct DC charging system installed. One of those helped a Roadster win two 24 hour endurance races in Europe, one being relatively recent. It might make getting service on your car at a SC a little more challenging, but it is amazing to see one in action (when you are sitting in your car waiting impatiently to get on with your trip). If you search the forums you will occasionally see more on group buys for these devices from the manufacturer. I think that when my new 3.0 battery's warranty runs out, I will reattach mine!
It is so wonderful to see someone getting their Roadster out there on the road for longer trips. Love it!!

As the organizer of the last group buy, I cannot recommend buying anything from QC Charge. We ordered them, paid deposits, and the company never delivered. Tony, the owner, refuses to respond to phone calls or emails. The company refuses to refund money. The company promised to deliver them over a year ago. If one does get in contact with someone at the company, one is told they still plan to produce them, but the group is extremely doubtful given the refusal to communicate. We are considering legal action.
It’s a terrible situation, but the bottom line is this: do not buy from QC Charge.
Should they ever deliver, I may have one to sell if the new owner of #609 doesn’t want it.
