Got a flat in the parking lot 30 miles from home. One tire picked up a nail on its tread so I decided to equip the car with an emergency tire kit and air compressor.
This portable AstroAI air compressor seems to be adequate for the price (got it on sale.) I didn't buy it for continuous weekly or daily use, only for emergency flat tire situations.
PROS - It pumps air into the tire, but it takes a while. It's compact, light, easy to use and carry, doesn't seem to heat up after 3 minutes of use, not too loud but it's not quiet either. When I plugged the 12V cable, it reached to all four tires on my Camry LE. Also, when I set the PSI to 35, the air compressor filled my tire with air and then abruptly stopped after it reached the desired number.
CONS - No bag/container for item and connectors (only the box it came in.) The quick connect head seems like cheap plastic. Don't know how long that will last? Also, you can't use this item in the rain. (I didn't think about that so I will have to make sure it doesn't get wet.) It only has 15 minutes of continuous use with a 10 minute break in between.
Other than that, it was a good buy for today, and I will keep it. Next time, I would get a waterproof or water-resistant air compressor.
