This worked great to inflate all 4 of the tires on my compact car but only 3 on my truck until I had to recharge it. Not bad for 7 tires on one charge. I did like the ability to change the pressure for each vehicle which was quite easy to do. I do wish that the hose was a bit longer, but the compact design made up for it.

Only had an opportunity to use it on a friend's truck so far. Not a monster truck but a big truck, big tires, three of them were quite low and it pumped all three of them up in practically no time at all and still had plenty of charge.

Woke up to a flat tire at a hotel on a business trip on a cold morning, hooked this thing up, and ten minutes later had over 30 psi, which was more than enough to get me to the nearest tire shop. Great for a single tire, but just know the battery isn't good enough for more than that, but that isn't the point of this thing. The point is to get you out of a pinch. Mission accomplished 👍

Everyone should have one in each vehicle, especially when going on a trip. This holds a charge for a long time but still, recharge periodically. Came in handy when on vacation and had a slow leak on the trailer. Easy to use, just set what you want and push the go button.

The Fanttik X9 Pro Portable Tire Inflator (5-Piece kit) from Sam's club turned out to be a solid companion for maintaining my Harley tires. It’s compact and powerful enough to quickly bring motorcycle tires back to the proper PSI. The digital display and auto shut-off make it simple and precise—no guessing, no overfilling. What I really like is that you can set it to a partial pressure and fill the tire in under a minute per tire, which makes it extremely practica. On a Harley, proper tire pressure isn’t just about comfort—it’s about safety. Low inflation can lead to dangerous slip-ups, especially during turns or sudden braking. This inflator gives peace of mind because you can check and fix your tire pressure anytime, anywhere. Overall, a reliable and convenient tool that every rider should keep on hand.

Very good, it's enough for all four tires. You can set the amount of air the tires need, and it's easy to use for both men and women. I really liked it.

I bought this for topping off and filling up bike tires before rides. It works really well and takes up minimal space in the vehicle. I haven't even thought of using it to fill up a car tire, even though it does have a setting for vehicle tires, I think it would do the job but it would take some time considering how long to fill a completely empty 29er bike tire. It is a little loud but only noticeable if it runs for a long time. I do like that I can preset a PSI setting for the bike and it seems to be pretty spot on.

Over headed quickly. With the cold front my daughter’s tires needed air. Each one was at 26-27 psi. I could only inflate 3 to 35psi before the unit overheated and needed to cool down to do the fourth one. These were tires on a small Buick suv not a monster truck. It basically could only put in 24 psi total before it had to cool down. It’s more than enough to top off a tire but don’t expect it to add 35 psi to one tire in case of a flat.

Poor pump, I would keep this pump for bicycles and footballs. I used this on a suv tire for 5 minutes and it raised the pressure by 1pound. Epic failure.

I liked the simplicity of this unit and was excited to see the high psi capability. However I was quickly disappointed it didn’t even get 20 psi in the tire before the battery was dead. Not worth the time or money.
