A:  Of course they’re not the same I use a 5 in mine it’s easier to carry for filling tires however any tool that requires hi cfm or continuous pressure spray paint, air chisel etc that’s when you’ll need a larger battery depending on the job I started switching to Milwaukee so I have an assortment of batteries to choose from and they don’t disappoint this tool is not an exception great to have for small jobs much quieter than my large compressor or any smaller ones I’ve used 

A:  The 12.0 will perform better

A:  I use it for car parts all the time and it works great. Not sure that it would have the capacity to do and entire interior. Does recharge pretty fast, so it might be OK.

A:  Struggle to keep up.

A:  It will work OK for short bursts used but not continuous use since this type of use takes a lot of air. If you’re a professional, this will absolutely not work. It needs time to recharge between use. For me, it does work. I just like that it’s quiet more than anything else. Cordless helps too.

A:  The short answer is no. The long answer is also no. This is a good compressor for small nailers and portability. At 1.2scfm there is not enough output for the jobs you described. At least not for any extended period more than a few seconds. The tank is too small and battery life is not long under heavy use either. You should find a way to estimate how much flow you need. For instance Home Depot offers a 20ga vertical compressor with 4scfm output for less money.

A:  I personally do not think this would do what you want it to do. It would be constantly running and would run through any battery you put in it. I’m a Milwaukee guy so I’m sad to leave this as the answer.

A:  Absolutely will be good for blowing yourself off using a hose and a blow gun.

A:  Yes, it can easily handle that.   You can adjust the pressure to the appropriate level you want.   I've bought two of these now because I liked the first one so much.

A:  It'd work.... It's only a 2 gallon tank though. If you're really dusty it'll have to fill up a couple times.

A:  Yes . 

A:  Yeah, More than enough CFM & PSI for the task.
