How much air pressure does it build?

Asked by Serapio April 11, 2021

I will confirm it has a good capacity, as they said in the specs. "High-pressure inflation of 0 PSI to 150 PSI for tires and small inflatables" Enjoy

Will this charger and battery work with a P5231 Jigsaw? Thanks

Asked by John March 18, 2021

Short and sweet...Yes it will All of their 18v devices use the same battery type...universal fit. Run time is dependent on the amp of the battery you use.

Asked by Potter March 4, 2021

It seems to be pretty accurate. definately 2-3 PSI .

The charger pulls up to 50w so I would plan for that amount.

After a year pumping up 2 or 3 dozen bicycle tires and other small tires it broke. Cheep plastic part inside burnt up. I was able to fix it might not last long.

Excellent product idea. My father in law bought my a Ryobi combo tool kit about 15 years ago. It had the old 18V NiCad batteries. Over time the batteries just couldn't take or keep a charge and the kit was shelved. Then this new Lithium battery and charger came to light. It still fits and runs all of my tools in the combo kit! I have now taken it to the cottage where just one battery will suffice all of my needs. No other brand has this great feature. They want you to buy all new tools too! They all should be required to follow this leader in battery powered tools!

I bought this tool online yesterday and picked it up this morning. Came home and waited for my tires to cool down as I knew all 4 of them were low, I have a gauge but my old compressor is more than 30 years old and I have large tires on my pickup so it just couldn't handle the task. Did some house work and walked the dog thinking I would be outside airing up tires for at least 30 minutes. Surprise! I was done in about 10 minutes. My tires need at least 38 lbs of air and I had one that was down to 22, all 4 were low. I put a 3Ah battery on and went to work totally pleased with the ease of use and power sipping ability for what I asked of it. I only used 1 bar off the battery.

Plastic garbage
Cheap internal plastic fan self implodes itself so that you are tempted to buy another. But I won't buy another. Not worth the waste of time going back and forth with Ryobi. Buy a better brand!

Accurate and Portable
I needed something that was portable for long motorcycle touring and this is perfect. It is very accurate and I verified with a digital gauge and is close to my motorcycles built in tire monitoring system. I'm very happy with this purchase.

Ryobi 18V ONE+ Power Inflator is a small but mighty little tire inflator. I used it to inflate the tires to my GMC Sierra and it inflated them from 23psi to 35 psi within 5 minutes or so per tire. The digital reader is a little off though but still worth a 5 star review. I suggest that you disregard the digital gauge while inflating the tire and let it go to get a more accurate read. Other than that I really do recommend it.

For quick reliable air, Ryobi 18-volt high pressure inflator is the way to go. It has helped me while out in the woods. I had a very low tire with no accessible spare tire. I was able to inflate and drive out of the woods. I like it a lot!

Just Buy It
If you are looking for a tire inflator this is it. For the value it is great. It fills my car and SUV tires quickly without issue. I am the neighborhood kids bike and ball inflator. The adapters it comes with even fills up my road bike up to 120 PSI no problem! One thing that could be better is to have a set point PSI so stop instead of holding the trigger and watching it, but for the price it can't be beat.

Excellent portable inflator
I needed an inflator for my suv tires, found this one on sale and bought a drill with battery that works on both. The inflator worked great topping off my tires from 29 psi to 33 psi in under a minute each. The manual states the tool needs to rest for 5 minutes for every five minutes of operation. I could tell the quick adapter and hose were getting warm as i was approaching the five minute mark after all four tires. I let it rest and moved on to top off the golf cart tires, with only one being low. Worked as expected. I had better results than some, as my TPMS, reflected the same psi that i set on the tool. Great tool to carry fully charged in the car for emergency, because in today's world you just don't know who your going to get when you need help. Comes with adapters for pool floats and toys, and one for sports balls. The gauge is large and easy to read, just snap a charged battery on and you are ready to go. Note, this tool came without a battery and charger, check the other box if you need those.Very please, would make a great Christmas gift.
