OAK&IRON Battery Tire Inflator 2X Faster Inflation Portable Air Compressor 150PSI Cordless Tire Pump with LED Screen for Cars, Bikes, Motorcycles, and Balls

I purchased this as I often drive far distances and am concerned about getting a flat/low tire with no assistance nearby. While I havent tried it on my car tire, I did try this out on a bicycle tire to see how well it worked. It was easy to connect and quickly inflated the tire. The noise during inflation time is minimal (so its not an overly loud unit). My only concern is setting the correct inflation amount. I READ all the instructions prior to using the unit. I watched video demonstrations. For the bike tire, I knew what the maximum PSI was for the tire. I selected the bike option, connected the tube to the tire and while trying to set the inflation amount it stared inflating the tire. The tire was inflated very quickly (happy about that), but I had to quickly turn the unit off to stop inflating as I didnt want the bike tire to burst. Perhaps a little more practice needed to use the unit, but overall it does the job.

I just received this, charged it and used it to fill up my trailer tires which were all between 23 and 25lbs of pressure. I used it to fill all four of them to 45.5 lbs of pressure and it did a good job. It used up all of its power to get the job done but it finished. Most of the time you are not going to use it to fill up four times so it should do a great job for any vehicle. PS, its actually very quiet compared to other electric pumps Ive heard.
