Reflate car tires, clean parts etc. Mostly home DIY use. On second thought, I do not need one but its nice to have.
I've got lots of thoughts!
Cordless vs. Compressor
A compressor is a pretty handy tool. Rancherbill is right too though. There's been so much cordless innovation that there's only a couple of tools you "need" a compressor for, then there's tools that are "better" as pneumatic, but only if you use them a lot.
I.e. You can't get a cordless air hammer, a high-power concentrated blower or a abrasive blaster yet. Those are kind of niche tools though, that you may not even want.
Pneumatic nailers are an example of something that's "better" than their cordless counterpart. I'm using scare quotes because it depends on how you use them. I use my 16ga cordless nailer more than any of my pneumatic nailers because I can just grab it and throw a couple nails into something - no waiting for my compressor to spool up - or easily take it inside the house for a quick project.
On the other hand, it's heavier and slower than a pneumatic nailer, so if I was building furniture or working in a shop, pneumatic is a better tool.
There's also tools that are just straight-out better as cordless - an inflator is one of them in my opinion. It's way easier to take your tiny inflator out to your car to top up the tires than wheel out a compressor and charge it up. Plus you can toss the inflator in your vehicle and it's quieter.
Pneumatic Expectations
If you're going to be a "heavy" compressor user, the one you posted looks too small to me. You won't be able to abrasive blast, use a pneumatic grinder, or use a paint gun without waiting for your compressor to catch up constantly. If you want one compressor to rule them all and you're going to buy a bunch of pneumatic tools, it seems likely you will need to upgrade.
On the other hand, it looks very capable for smaller pneumatic tools - nailers, most air hammers, die grinders, etc., and for blasting dust off things. It seems like a good price too. I think it's a good pick actually, provided it meets your use-case. It seems like the size a contractor might bring to a job site.
If "all" you really need is a quick air blast, occasional tire-inflation duties and other non-intensive compressor uses, you might even choose to go smaller. Yes it will be slower and inflate more often, but there's something to be said for a compressor you can easily pick up or store on a shelf.
