Review on AKASO P10: Portable Digital Tire Inflator with Auto Shut Off, LED Light, and Electric Gauge - Ideal for Car Tires, Bicycles, and More by Jamar Gow

This automatic digital air pump is remarkably light and compact, although the product description is accurate. I had no problem connecting the 12 volt inflator plug to a 12 volt lithium ion battery source. This was for my convenience, not because I couldn't plug the inflator into the car's 12-volt outlet. Having not used a Li-ion battery for a while the voltage has dropped to 10.1v but the Akaso inflator passed my test with an estimated 3lb drop in our car tire with no problems. I left the 195/65R15 tires at 41 pounds, so I pumped up the low tire from 38 pounds to 41 pounds. It only lasted a minute and a half, even at suboptimal voltages. It's fast enough in my book. My short video shows the second video-only test I did, from 40lbs to 41lbs. You'll notice how quiet the pump is, not to mention the noise level of traditional tire pumps. It was very quick again. The pump stopped at 41.5 lbs, probably due to the short barrel. I checked the accuracy of the readings on my analog tire gauge and they match 1/2 lb 2 white LEDs and one red LED alternating between white, flashing red and SOS red. The LEDs aren't very bright, but they're good enough for task lighting when inflating tires at the side of the road or in a dark garage. On the back, opposite the manometer, there are 4 rubber struts for vibration damping. One bar came loose on delivery but easily re-sticks and stays in place. It's worth the modest price.
