BULLSEYE PRO Tire Inflator with Pressure Gauge, Compact and Portable, Automatic Shut Off, 150 PSI Max, USB Home Rechargeable and Cord for Vehicular Use As Seen On TV (9475)

Dang! I love a good tool! This one was a little intimidating and I kept it in the box for a while. Finally, when a car I don't drive anymore had a really flat tire in the driveway, it was time. I read the instructions that are easy to follow. The lithium battery comes charged already which helps. I unscrewed the little cap on the tire stem, placed the thing that goes over it from the device, and easy to push down the little locking device. All you need to do is to press the "on" button until the window lights up (and btw, there is an automatic flashlight that comes on in case you are in the dark). Next you just increase the tire pressure you want, in my case it was 44. I pulled the trigger to start the unit, and yes, it's on. The tire pressure said 6! (Which is also good bc it tells you what the pressure is before you start.) So this tire was really flat! I watched as the tire pressure increased, in 1/2 pound increments. It's pretty loud, but you know it's working. So I waited, and it was inflating, and after about 5 minutes, I stopped it at 35 to take a look (pulled the trigger to stop). OK, looks good, keep going. Started it up again, it was already set to 44, so now it's going from 35 to 44. When it hit 44, the unit stopped automatically. I unlocked it from the tire stem, put the little screw thing on the tire and all good. Came inside and plugged it in to keep a good charge. Next day, also rescued another car I had at another location, haven't driven it for a while, 2 tires a bit low. Took like a couple minutes between tires, and voila! No need for AAA! This device REALLY works and I'll keep it in my trunk just in case. Next I'm tackling some vintage basketballs that have lost air, will be able to do with the adaptors (they are in the device, in the front, just open the little door.) Believe me, you will love this product! Great for anyone who has that oh no moment when you need to get somewhere and now what, tire is low. Just fantastic and worth every penny!

Excellent. RV tires are harder to inflate than regular car or truck tires because RV trailer tires have a high pressure 65 psi to fully inflate mine. It works so fast and it’s so lightweight and I put it in a box so I don’t set it down and get it dirty and then once I get everything hooked up, I hold it. It has lights plus It tells the percentage of battery left and you program it to the psi you want and it stops at that psi and it locks in place. You don’t have to hold it. It’s fantastic. You get excellent quality for a very inexpensive price.

Works great on our car and bikes. Takes no time to inflate and is so convenient.

Today got an E-1 error even though i charged over night. I removed the battery pack and reinstalled and then it was good. it worked for 3 tires before the error so not sure but glad it helped as it does work well and stops at correct psi.

Great item to keep in your trunk in case you have a need for some air in your tire! Very easy to use not complicated at all! Only had it for a little while so far so good!

I have used this several times already to air up the tires on my Crown Victoria. Tires at 16 psi took 3 minutes to bring to 35 psi.This tool does get hot, and instructions state to not use continuously for longer than 15 minutes. I use it much less than that. It automatically shuts off when the preselected tire pressure is reached . I have absolutely zero issues with this tool and am very satisfied with it and its performance. This would make a fantastic Christmas present!

This tool is lightweight and easy to use. It works best when the battery is fully charged, and a digital display shows the power remaining. It inflated two flat trailer tires to 50 PSI in a few minutes, shutting off automatically so I could attend to other things. I inflated a wheelbarrow tire, two small trailer tires and four lawn mower tires on a single battery charge. Recharging requires up to three hours, which was fine because all of my work was done. The LED light is helpful to read the PSI words on tires. The instruction manual is clear, but I had trouble finding the small extra nozzles, which are stored in a small compartment on the lower front of the tool. It is a smart way to store small accessories. I do not know how long the battery holds a charge, while in storage. This is a well-designed tool and was a good purchase which will serve me better than the large steel cylinder air compressor I had used for years.

East to use, performs exactly as advertised. Only negative is that charge does not hold long—can inflate one tire & the need to charge again.
