The ~~NACS adapter~~ DC-to-DC converter is limited to 50 kW:
Saved you a click.
It's not a limitation of the adapter itself. I mean it might be, but the architecture of the battery is the bigger issue. Lucid (and several others including Hyundai/Kia and VAG) use 800V batteries and most superchargers are only compatible with 400V. The new V4 superchargers support 800V+ charging though. At that point the adapter may become the limiting factor.
Fair point, I've updated my comment!
But can they still use a decent adapter and charge at 250 kW?
The comments seem to indicate that it's an issue with the Air's DC-to-DC converter as it tries to step up the 400V the Superchargers provide to 800V.
Big oof. Thanks!
