Can you hook this up with an small air compressor? Plus do yall have any Recommendation?

So I was reading on the website that it will fit the Honda Crv, I'm really wanting to order these and see if they will fit on my 2022 Accord. I know its an suv but they share a lot of the same components,are all of these a universal diameter or different sizes for each model vehicle? I have a cargo carrier for camping and when I load it up to 150 pounds or so my car really squats in the rear so I've been looking for something to help stiffen the coils.i almost bought the rubber shock absorbers but they seem like they maybe wayyy less effective.
