My car has a 120v outlet. I would expect that there are low current draw 120v air compressors available.
But you don't want an air compressor, you want an inflator.

I think this is a very important distinction. There's no reason to pump air up to 100+ psi, then blow it down to 30+ psi. Especially if you can get a higher-output pump that works at a lower pressure. Like this one. https://www.amazon.com/gp/product/B0036E9VB6/ref=s9_top_hd_bw_bAVoap_g263_i6?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-4&pf_rd_r=PZF5NN2AAXHEXZSAF0PR&pf_rd_t=101&pf_rd_p=97096c9a-ee44-5b6f-b18c-f34d4819839a&pf_rd_i=155346011
(I know nothing about it, other than it's 60 psi max, and a higher cfm rating than other, higher-pressure rated inflator/compressors.)

Well, a true 1 hp electric motor, even with a 100% efficient inverter, would require about 60 amps at 12 v to run. You aren't gona run one off an inverter you get at Best Buy. An inverter with enough capacity to run a 1 hp electric motor isn't going ot be cheap, and it's going to have big fat cables that will have to be connected directly to the battery or similar. ie: It won't just plug into a cigarette lighter socket.
On the other hand, most "horsepower" ratings on compressors are complete lies.
Has he considered a tire pump? If you get a decent quality one with a larger diameter barrel it really doesn't take that long to pump up a tire.
