Review on Kensun 12V DC Portable Air Compressor Pump - Enhanced 150W Digital Tire Inflator for Cars & Inflatables: Efficient and Reliable Performance by Luis Jacob

This was a great purchase, it works well and is well made. The compressor is powerful enough that you can add 10psi to a tire in 5-10 minutes. I haven't tried blowing up an apartment with it yet. The auto shut off is easy to set up and works very well. After checking the tires several times with a pressure gauge, I don't do that anymore. I just set the digital cut off pressure and use the auto cut off. Easy. I take it with me when I travel, so it's nice that it comes with a nice carry case to keep everything together. I also use this to adjust my tire pressure for seasonal adjustment as I live in a full 4 season zone. Overall this is a great purchase.
