This is a nifty battery powered inflator from Baseus. I have another Baseus version of this and I use it quite a bit. Mainly for my escooter, bikes and sports balls. It might sound lazy (I've still got hand pumps I'm happy to use too) but being able to set the PSI and just let it do its thing while I'm doing something else to prep the bike is useful and a timesaver. Especially if I need to prep everyone's bikes for a family bikeride. I'm always the sucker that gets to do that.
I've tried mine with the car and, although it works, it does take a while. Fine in a pinch if you're out and about but you wouldn't want to be in a hurry. I'm talking perhaps 5 minutes to add 5 psi on a car tyre.
Would recommend one of the ones off aliexpress with an 8000mah battery
Get far more use out of it for the same price
