18V ONE+™ High Pressure Inflator with Digital Gauge
18V ONE+™ High Pressure Inflator with Digital Gauge is rated 4.7 out of 5 by 21.
Rated 5 out of 5 by from Great Great Product! So happy with this. Over the years I have used so many inflators- many that had to be plugged into the car cigarette lighter or into a regular outlet or extension cord. But they are not convenient at all. This is the Holy Grail of convenience. Just pick it up and go to your car tire, bike tire, raft, float- whatever. IT'S POWERFUL! Just be smart and don't push it for extreme amounts of time and risk overheating. But that's pretty easy to avoid. This is a 5 Star PLUS!

Rated 5 out of 5 by from Very convenient Bought this digital high pressure pump to replace my original ryobi pump. My older one lasted a long time inflating kids bike tires, pool toys, vehicle tires, and even balloons. I was happy with how long my original lasted, so I didnt hesitate to buy this updated version after mine started failing (after 8years, first the hose disconnected internally, I was able to crimp it back on, then the hose blew a hole in it, so I cut the hole out and reconnected a the shorter hose.) But the it finally started acting up after filling up/topping off a couple rv times 80 psi. I think I overheated it, still works, just not as good. These tools need a break here and there. If this one lasts as long as my first, I'll be happy. This has a longer hose and a digital pressure gauge, and it is quieter. Ryobi is always pushing to improve their tools.

Rated 5 out of 5 by from Simple to Use! I just bought this last night, and had already inflated all my car tires to proper PSI within the hour. I was sick and tired of wasting money on broken air dispensers at local gas stations. This tool was affordable, perfectly interchangeable with the rest of my Ryobi tool set, and made filling my tires a cinch. Ready to hit the road again! Highly recommended!

Rated 4 out of 5 by from Surpisingly Powerful Inflator Jus bought this and crazy $20.. I just filled up 2 cars.. 8 tires. Works great. Digital gauge is good.. but not calibrated. it was about 1pd psi off. from my separate Digital gauge and confirmed from my Tesla's tire Monitor. But a great buy.. Might have to just buy another one to keep in my car.

Rated 4 out of 5 by from Does what it does Bought this to fill up bike and car tires and the occasional sports ball. There's nothing particularly amazing about it. Inflates things nice and easy. The second high pressure nozzle doesn't work very well but overall it works and does what its designed to do.

Rated 5 out of 5 by from Works great I've used this once so far and it worked great. Took less than a minute to inflate my tire from 27 psi to 32 psi. Only downside is that the guage reading while you're inflating is not accurate. You have to stop inflating to get an accurate reading.

Rated 4 out of 5 by from Great Little Air Pump Great for pumping up small things like balls, bike tires etc. The only thing that is missing is a lock to hold down the button to continously pump air into larger items like air mattresses and car tires. Other than that, its a great product.

Rated 4 out of 5 by from Great but, As all my other Ryobi tools, this one is good. However, according to its manual it should only be run 5 minutes at a time. Then it has to rest for 5 minutes before starting up again. This is rather inconvenient.
