I have that compressor. Haven’t had it very long, about 3 months or so.

So far, so good. I’m very happy with it. It’s quiet, as advertised and it’s done all I’ve asked of it.

Do you have a specific question?

Is that an oil less compressor? I have much better luck with compressors lubricated by oil.

Well One question I have is I know it max PSI is 150… Is that big enough for Tools and spray finishes?

The ‘how much is enough’ question can be very hard to answer. Giant can of worms hard. :-(

Here is typical chart of average CFM required for various tools randomly grabbed from WWW:
https://www.industrialairpower.com/wp-content/uploads/Air-Compressor-Consumption-Charts.pdf

Note these charts are an average. Only your tools can define what you need.

Example: There are HVLP spray guns that need 20-25 CFM to work properly, despite average gun needing only 6-9 CFM. The high CFM is one reason that dedicated units like the Earlex sprayers have 2-3 stage turbine pumps inside.

The Kobalt unit above is single stage pump rated 4.5cfm @ 90psi.

IMHO – It should work for most hobby shop tools, but will struggle with high duty cycle use on tools like 1/2” impact wrench or HVLP gun with 2.0+mm tip size commonly used for spraying latex or heavy body clear coats.
But YMMV

FWIW – Any compressor/tank will run a high CFM tool for short 1 min use per hour with larger enough lines/fittings to support the flow rate. It is the duty cycle that often defines the peak size of compressor. The challenge is heat build up in compressor when run continuously for hours-hours while you spray/grind/blast/etc. Commonly the oil-less compressors are not rated for continuous duty operations. Don’t see where Kobalt lists the duty cycle?

Bottom line: Only you can determine if it meets yours needs.

Sorry for not giving an easy yes/no answer.
The only easy answer with compressors is do you need a water filter for spraying – yes.

Cheers!

Can’t add much to what CaptainKlutz said.

I’ve seen done HVLP guns as low as 2 CFM @ 90 PSI.

I don’t plan to use mine to spray. It will mostly be used to power small nailers, and possibly the occasional impact wrench, die grinder or small sandblasting setup.

So far, I’ve used it to shoot a couple thousand framing nails, a few finish nails and fill some tires.

I was a little concerned about it being oiless, but based on the reviews, I decided to take a chance. The low noise level at that size was the most important feature for me.
