I hear a lot about public charging stations, and my employer is also installing some at work. These look a little smaller than the charging port on my Roadster, and I'm guessing they are the recent IEEE standard J1772. Wikipedia says that this is a 5-pin connector, so it can't be directly compatible with the Roadster's 4-pin port. Does anyone know anything about availability of adapters that might work?
(I did not find any specification of the Tesla port either on the web site or in the owner's manual.)

I saw a mail message from Tesla recently that said it would be available by the end of April. Many of their promises have dragged on and on (we still don't have an online map of HPCs, or a way to get notified when charging stops) but that's a more specific date than they normally give.
The most annoying part is that while the J1772 spec goes up to 80A, most charging stations being installed only support 30A. So it's going to be slow going if you use one...
Some Tesla owners are converting their Roadsters to a J1772 plug - but I've decided that for now, I'll stick with the adapter. I want to be able to use an HPC when available (for the faster charging) and carry the J1772 adapter for the times I need it.
When the public J1772 charging stations start sporting a higher amperage, I may rethink that.
I hope Tesla's adapter will too.

Only 1/25 the price of the charger!
I was stranded and they had to drive the adapter down to me so I could charge and get home. The Meno Park crew is really excellent, I must say.
So now I have "bought" my adapter, which is on "back-order" if you believe that. Please anyone let me know if you have actually recieved your adapter yet. Customer service says they are "back-ordered" 5 weeks. However, they have pushed back the actual release date several times and it makes me wonder if they have shipped a single adapter yet.
I used the adapter on a Tesla charger that has been converted to J1772. I charged for 1.5 hours and the adapter worked great. Now that the Tesla chargers are being modified, the adapter is a huge help and well worth having.
I also ordered mine within a minute of receiving the email. People that ordered later in the day saw the 'backordered' message.
I'm thrilled to have it.
Or by chance is a firmware update needed to use the adapter?
Thank you
I've located a J1172 charging location nearby and am going to check and make sure everything is working before taking off on a roadtrip next weekend. I was planning on testing it anyway, but because of your problem, I'm testing early to give me time to troubleshoot.
Have you tried any other locations?
This is with a 2.5 roadster though, with a recent FW update.
Hope that helps some others with questions, sorry I couldn't answer your questions directly DHrivnak:(
I thought I'd best test out my adapter before heading out on a road trip. Conveniently, the ClipperCreek office/mfg site is just 8 miles away from my driveway, and has both a Tesla HPC and J1772 listed as available.
I had the same error message when connecting to the J1772 standard. But the good news is that the entire ClipperCreek engineering crew and CEO came out to troubleshoot the problem. First we tried the Tesla HPC. No problems charging. Then tried the J1772 again. Nope. Same error message.
Then the guys opened the charger, dropped the signal from 75 amps to 70 amps. It worked like a charm. Tried it back at 75. It quit working.
We called Tesla and they're going to get back to me. And work with ClipperCreek on this. But clearly the cable didn't handle a 75amp signal as I thought it would. The firmware update didn't address this. ClipperCreek personnel were surprised, since they thought through conversations with Tesla that this had been addressed. But the phone call confirmed the firmware update was to handle problems with Coloumb only.
The adapter doesn't do me a whole lot of good if I'm not able to take advantage of higher amp charging stations. I'm not okay with that. I've been promised a reply - and will go back to ClipperCreek to test there once I know a solution.
I previously tried this one which is only $260:

It seemed like a nice unit, but I tried it on three different Coulomb chargers and kept getting a ground fault error so I returned it. Sounds like maybe the firmware update was the issue. I think I'll stick with Tesla's anyway so it's Tesla supported (if I can get one).
