What psi does this output the air at? because a hair dryer has little psi and does not work compared to a compressed air can?

It does not use compressed air or have a pump. You may need to compare its velocity and CFM to your needs at comparable PSI of other methods (ie air compressors, canned air etc),

How do I reach this company? I got mine today and it’s been charging all day and hasn’t turned on. Just my luck

You can contact Amazon customer service directly. They will send you a replacement. It is a piece of junk. Mine stopped working after 4 months.

What is the warranty for this item? I purchased it in August and used it 2 times. I charged it up yesterday and tried to use it but it wont power on!

I had the same problem as you. Mine last 4 months, the replacement last only 1 month!!!! 6 month warranty. You can call AMAZON custom service. They will send you a new one and return label. DO NOT Contact the seller. Too much trouble from seller.
