Rated 4.2 out of 5 by 119 reviewers.
Rated 5.0 out of 5.0 by Sure beats pumping up a bike tire to 90#s by hand!!! I ride bike every day. So many times when I went to take my bike off the carrier, I noticed that the tires were softer than optimal. I used to pump them up with a small hand pump.......but getting them to 90#s was quite a task. Since purchasing this Ryobi 18-Volt One Plus Cordless Inflator, I set the pressure I want and watch the pressure increase rapidly to the proper pressure for efficient rolling. I have topped off my tires, along with my wife's, more than 20 times......all on the first battery, and it's still going strong!!! GET ONE!!!!! August 6, 2014
Rated 5.0 out of 5.0 by Must have travel accessory I bought this for checking our travel trailer tires since it is not easy to get to pumps when traveling and we use the Ryobi drill for out trailer jacks. One charger and battery to cover both needs. It works great and you just set the pressure and it shuts off automatically. I checked it against our dial tire gage and it was right on. Did the truck and trailer, 8 tires easily without recharging. How often to do you check your spare tire pressure? Take this along and don't worry. February 7, 2014
Rated 5.0 out of 5.0 by The perfect inflator I bought the Ryobi Inflator after watching several videos and they were exactly right. Nothing could be easier to use. Follow the instruction simply insert a 18v Ryobi battery choose whether you are inflating a air mattress or tire. If it's a tire set the desired pressure adding 1psi to cover loss when disconnecting. Turn it on and walk away as it will automatically turn off when done. The inflator when used to inflate a kiddie pool or a air mattress is even better as it can also deflate getting out that last little bit of trapped air that always seem to remain. Yes , I would diffidently recommend particularly if you already have the Ryobi 18v + one system. June 24, 2014
Rated 5.0 out of 5.0 by awesome inflator for multiple uses Like others have said, this is a great cordless inflator. I use it to quickly fill my large river raft, inflatable kayak, truck tires, trailer tires, etc. It works on them all. I absolutely LOVE that I can set the pressure, have it start and walk away for a second and let it run. When it reaches the pressure, it shuts off on it's own. That feature alone is worth the price. If you are looking for an inflator for the pool toys or something to keep the tires on the car/truck at the right pressure and already own the Ryobi 18V batteries, this tool is the ticket.

Rated 5.0 out of 5.0 by Fast Inflator for Tires! I use this P731 Inflator with the 18v Lithium Ion batteries and it does an excellent and fast job of inflating truck and trailer tires. I was really surprised at how fast it inflated some trailer tires from 35 to 50 psi. And I really like the autoshutoff feature for filling tires. The digital gauge appears to be a couple psi high compared to my pro tire gauge. I set the digital gauge to 50 psi but it only inflated the tire to 47-47.5 psi. My pro gauge is accurate to +/- 1 psi. So I would recommend comparing the final pressure to a known accurate gauge and then just adjusting for that difference. Overall a really good portable inflator. January 10, 2012
Rated 5.0 out of 5.0 by Ryobi air compressor wirks great Easy to use, pretty powerful,very handy. The printed on the instructions are a great idea.You never have a low or flat tire near a compressor,this thing makes low tires no problem.One word of caution,don't leave it out in the rain.

Rated 5.0 out of 5.0 by Excellent portable tool - would recommend highly We purchased this to take with us on the road for inflating and deflating water crafts and it works very quickly. July 7, 2015
Rated 4.0 out of 5.0 by Great Air Pump This air pump is a nice easily portable pump that uses the One+ batteries from Ryobi. The reversible air pump makes dealing with inflatables really easy. The unit is small and light enough to carry in a beach\pool bag and being able to inflate on site and then actively deflate means that inflatables become easier to transport and MUCH easier to repack. The tire pump is programmable so that you can set the pressure you need and walk away. This works really well and means you don't have to sit there watching the pressure. When you hear the pump shut off, just go move it to the next tire and restart. At about the size of a Pepperidge Farm bread loaf, it takes up very little room in a vehicle. Pros: Very light especially when used with the compact battery Various sized connections Much smaller than typical air pump Digital pressure gauge Auto pressure cut off Low battery usage Cons: Somewhat loud (though still not as loud as a typical air compressor) You have to hold nozzle in hose when using for inflatables Tire inflation is a little slow Cheap feeling (though that's mostly because it is so light) June 22, 2015
