I know that the Lucid Mobile charger itself does not and will not support this, and that's fine.

But IF I were able to get an EVSE that supported it (eg. Tesla Mobile charger has 3rd party plugs for TT30), would the Air even charge at 30A 120V?

In theory I don't see why but, but I've read that some cars won't charge more than 1.2KW (120V 12A on a 15A circuit) at 120V, even if the EVSE supports more than that.

Does anyone know if the Air will?

I ask because I make trips up to my friends cabin in VERY rural Arkansas and they have a 30A RV plug, but I don't think they can support a 240V upgrade (and not sure I could afford to have it done for them anyway). I can charge at the normal 1.2KW rate, but by the time I get to the cabin, I'm lucky if I still have 30% SoC, so that's 40+ hours to get back to to 80%. Getting that doubled amperage could be really handy.
 
No
I see no indication that you can draw more than the design criteria. And 120 v outlets are not typically more than 15a.

No that's not what I'm asking.

They're are 120V 30A TT30 outlets usually used for RVs. There are a few EVSE solutions that support that (eg. Tesla Gen2 Mobile charger with a 3rd party adapter).

There is the "regular" plug Lucid provides then this one. I bought this adaptor with zero issues. Not sure what the plug is called other than a 3 prong 220-240v plug.

There is a female end for the Lucid one to hook into. I know some folks may question doing this, but it is reserved for emergency cases or when we go to the family cabin in West Virginia (nearest Level 2 chargers are 1+ hour in Snowshoe, WV; nearest RV site a 10 minute walk down the road). We had zero issues with the plug and Lucid adjusting accordingly.

NEMA TT-30 is a 120-volt, 30-amp RV and travel trailer receptacle that delivers a maximum continuous EV charging current of 24 amps (80% of the 30-amp circuit limit per National Electrical Code guidelines).

Key Facts About TT-30 EV Charging:
  • Voltage and Amperage: It provides 120V (not 240V) and a safe continuous draw of 24A (~2.8 to 2.9 kW).
  • Charging Speed: It roughly doubles standard 120V household (NEMA 5-15) speeds, adding about 10 to 12 miles of range per hour depending on the vehicle.
  • Safety Rule: A TT-30 plug is 120V, unlike a NEMA 14-50 (which is 240V/50A). Standard dryer or welder adapters will not work and can damage equipment. You must use an EV-specific TT-30 adapter or mobile connector setup that either auto-limits or is manually set to 24 amps.
Compatible Adapters and Equipment:
  • Tesla Mobile Connectors: Third-party or specialized adapters like the AC WORKS G2 EV TT30-24A or options from brands like WenStorm and HiFind can plug into a TT-30 and interface with Tesla Gen 2/3 mobile connectors at 24A.
  • Adjustable EVSEs: Portable smart chargers like the Grizzl-E Mini can utilize a TT-30 source by manually overriding or adjusting the internal/app settings to a 24-amp 120V limit.
Note on Forum Consensus: Users on forums like Reddit EV Charging Discussion note that vehicle capabilities vary widely—while Teslas, VW ID.4s, and Rivians can pull the full 24A on a TT-30 setup with the right adapter, many other EVs default or cap out at 12A or 16A on 120V circuits regardless of the 30-amp supply.

  • Adjustable EVSEs: Portable smart chargers like the Grizzl-E Mini can utilize a TT-30 source by manually overriding or adjusting the internal/app settings to a 24-amp 120V limit.

Yeah I wasn't looking for an LLM hallucination copy and paste.

As noted in my post, I already know there are adapters and EVSEs which will do it.

My question is specifically about whether the Lucid Air will actually charge at higher than 12-16A at 120V, since some cars won't even with an EVSE that does.

Let me be clearer
The lucid portable charger (cable) does 120@<=15 amp, 240@80 amps (or less).

If you can pull more than that from 120v with that charger then I’m not aware how but not with any adapter.

I don’t see how you can change that

I KNOW the Lucid EVSE won't do it. It's one of the first things I said in my original post.

But there are other brands of EVSE that WILL do it. I know, 100% verified that they do exist.

But I also know that the car itself has something to say about the matter.

Some cars will happily accept up to 24A at 120V, when the EVSE supports it and signals that it can. But there are some cars that won't accept over 12A (or 16A) at 120V, even when the EVSE does support it and signals that it can deliver it.

That's the information I'm looking for, to see if anyone has actually tried it and found success or not.
