On November 4th, 2026, I published a review of Roam Energy’s Power Bridge Pro V2L bidirectional charger, which currently works with more than 70 EV models.
Since publishing that review, I’ve learned something new that’s important for Tesla owners to know, but really, it’s worth all EV owners being aware of. Clean Technica reports Tesla pushed an over-the-air update, causing some Teslas to stop supplying power via third-party vehicle-to-load devices after a few minutes.

Clean Technica also cited posts confirming the issue in the Tesla Motors Club forum. That raises the question of whether there was just a glitch in the update or whether perhaps Tesla has decided to try and block third-party V2L units.
Of course, I immediately reached out to ROM Energy and Tesla.
Roam’s CEO and founder, Lydia Lee, told me, “Roam is aware of some recent V2L issues,” saying in part, “In Europe, Tesla firmware 2026.38.32 caused some CCS connections to drop after a few minutes. About a week later, Tesla released 2026.38.6, and PowerBridge started working normally again.”
Lee said Roam Energy is increasing its R&D department staffing to ensure timely firmware and compatibility updates. When asked whether Tesla is intentionally blocking third-party V2Ls, Lee said, “Based on what we’ve observed, we don’t have enough evidence to conclude Tesla is deliberately blocking third-party V2L devices.”
She went on to say, “We’re not relying on future Tesla updates to resolve this. Our team is actively working on our own solution while continuing to monitor compatibility across different vehicles and firmware versions.”
Lee added some of her Tesla customers reached out to share that their EVs are once again working normally with the PowerBridge Pro. One Tesla owner sent in a video that included a stopwatch timer and clock to help show and verify the PowerBridge continuing to work normally. You can view that video via a shared Google Drive link.
I reached out to Tesla’s official press email to ask if Tesla plans to purposely block third-party V2L devices. But after five and a half days, I still haven’t received a response at the time of this posting. If Tesla does respond, I’ll update this story post.
Let me stress, I don’t actually know if what Tesla did was an attempt to block third-party V2L devices or a simple glitch. But either way, it’s worth reporting.
And I’ll take this a step further. In the age of over-the-air updates and dealer flashes, it’s important for all of us to realize that things can change, and sometimes it doesn’t result in any perceived improvement.
