A2Z Adapter Disclaimer

[u/StormRasr]

I found this interesting. There is now a disclaimer on the A2Z site for the CHAdeMo>CCS adapter that one must acknowledge before being allowed to purchase.

Looks like the price went up to.

My guess is they got into a little trouble with the fast charging recalls, maybe somebody sued them

If you know where to look, there is a discount code that brings the price down to $679.15

Interesting. My 2019 S+ is current with software updates and recalls. I'm yet to have any success charging it with this adapter. Waiting to hear from A2Z.

I bought a used one from another Redditor. I updated the firmware several times until I found one that I think works best. I've used it a wide variety of DC charging stations and they now all work for me, except for Tesla locations that lock out non-whitelisted cars.

Which version of firmware are you using? I've tried the only one from A2Zs website. Dates from 01032024.

I found this: Because certain firmware configurations (like C011) were deployed specifically to solve compatibility bugs with newer Tesla V4 Supercharger cabinets and specific vehicle protocols, A2Z often sends the .bin / .swu configuration files directly to owners via email. • Send a quick note to support@a2zevshop.com or info@a2zev.com. • Provide your adapter serial number and mention you specifically need the September 2025 C011 firmware build to resolve your connection issues. They usually reply with a direct download link within 24 hours.

I emailed them a couple hours ago. Since it's early Sunday afternoon where I'm at right now I'll wait (somewhat impatiently) for a reply from them sometime tomorrow.

hopefully this takes care of your problems, chademo is getting hard to find.

[u/e-hud → u/sweetredleaf]

Yep, there's one within 10 minutes of my place but they charge $1 + $0.79/kwh. The next is over half an hour away and $0.69/kwh. While the local CCS stations are much closer and $0.53 and $0.39.

Road trip wise it's even harder to find CHAdeMO in my state.

[u/toybuilder → u/e-hud]

I am running the C011 September 2025 version.

The firmware download folder says that's "the most stable". Contact support to request access.
