Questions & Answers


is it in stock at galveston tx

Asked by kent February 12, 2021

It doesn't appear to be currently in stock in your area. However, P737DKN which includes a battery and charger can be shipped to your house or your store.

Does this have auto shut off?

Asked by Relentless February 4, 2021

It shuts off when the targeted pressure is reached

When will this be back in stock, and will it still be on sale when/if it is??? Sort of a tease if...

Asked by Josh January 21, 2021

Ha! I'm just another customer but home depot forwarded your question to me. So, I'll answer it. I don't know, I'm just a customer. Don't get your hopes up between the depot and ryobi sales, once it over they've moved on. I bought a set on "sale," but it was a nice set. The recip saw started smoking and they said all I can do is return the whole set (3 tools) for a refund. I haven't even USED the screw-gun/drill or the circular saw and they have to get sent back. To me? That's senseless, but they've been in business a while now, so they must know what they're doing...? On the other hand, if/when you DO get their power inflator kit you WILL be happy, it's amazing! I have two vehicles so I'm probably buying another one.

Will the connector fit a presta valve on a road bike? Thanks

Asked by McDish January 13, 2021


Will this work with a Ryobi one+ 18v 1.3 ah battery?

Asked by ch January 7, 2021

Works great. I use it with 18 inch suv tires. No problem.

Will it fit presta valves

Asked by Frank December 31, 2020

yes It has a attachment to do that.

Can this be used to put air in a go kart tyre?

Asked by 000racing December 29, 2020

Yes. My son used it for my SUV tires.

What is the maximum pressure provided?

Asked by Buzz December 24, 2020

Hello Buzz, The maximum pressure provided for the RYOBI 18-Volt ONE+ Lithium-Ion Cordless High Pressure Inflator with Digital Gauge (Tool-Only) is 150 psi. I hope this helps and thanks for contacting RYOBI! - Eve

I have a RYOBI 18V 3AH battery and charger. Would it work with this inflator?

Asked by Leib December 24, 2020

Hello Leib, Yes the RYOBI 3 amp hour battery is compatible with the RYOBI 18-Volt ONE+ Lithium-Ion Cordless High Pressure Inflator with Digital Gauge (Tool-Only) P737D. Thanks for asking! - Eve

Can't find one in our area, closest one is 52 miles away, area code 33563

Asked by Beaver December 22, 2020

Most are only available through the Home Depot website. I got lucky and found one but I have had to order online in the past.

Can inflate tires with both Presta and Schrader valve
Pleasantly surprised by this handy battery powered tool. Convenient compartment for adaptors. It does a good job to inflate tires with Presta or Schrader valve

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.

Keep your receipt! Or buy a better brand.
I have had this for a little while now, and have probably used it 25 times. The gauge is horribly inaccurate, but it's consistent. For example when I want my tire inflated to 34 PSI, I just fill it up until the pump gauge reads 40 PSI. I have tested this with 3 other gauges. Sidenote, always have at least 2 gauges because everything is junk these days and notoriously inaccurate. I have a professional one and a couple others. The few that I have that are inaccurate get thrown away or returned. I created a ticket with Ryobi because my inflator was rattling badly. They replied and told me i needed my receipt in order to help them. Of course I understand that, but was hoping they could at least look up the date of manufacture with the provided serial number. After they denied my warranty claim, I decided to take it apart and see what the problem was. You can see in the photo that the cooling fan blades completely disintegrated. I'm gentle with my electronic tools, so I know it wasn't from being mishandled. It's just made from cheap, chinese plastic. I won't ever buy a Ryobi product again, which is too bad because I liked them, but what they say about you get what you pay for applies to Ryobi. Total garbage.
