    This tool is much handier and more powerful than you would think. I bought mine after seeing and using my brothers. He has an RV and space and weight are at a premium. He knew that he needed to carry something in case he needed to inflate a flat tire. I tried to get him to buy a compressor for about $100 and much more weight. He decided to go with this and I was skeptical. In years past (okay, 30 years past!) little compressors didn’t pump a lot of air and would burn out and seize or melt before you could blow up a good sized bicycle tire let alone anything else. I used his pump on a leaking motorcycle tire that needed pumping up to 40 psi every 20 miles or so. It was a pain in the you know what but it got me home. Each time I used it the tire filled rather quickly. Lightweight and easy to use. His unit had a dial air gauge where this one is digital. I have no idea how accurate the gauge is, but it’s close enough for what I need. My brother tells me that he can pump up his RV tire to 80 psi without any problem. As soon as we got home from our motorcycle trip I ordered mine. Be aware that this is the tool only, you will need a battery and charger. We have other Ryobi tools so this was not a problem for us.

    This is a super win at $30! Ryobi is known for making pretty good tools for home users and this one is a home run! It pumps up tires really fast and is so practical you will actually keep your tires at the right pressure. It has a digital readout that is so easy to use! I like some of my Ryobi tools, my narrow crown stapler by Ryobi is my all time most used tool. I used to think Ryobi wasn’t good because they weren’t commercial quality tools like DeWalt, Makita, MIlwaukee, etc but I’ve found that I really like some of their tools at half the price of the big boys!

    I stumbled across this by accident and bought it on sight.I’m big into biking and got sick of my big, clunky bicycle pump and the battery fits from my Ryobi leaf blower so that worked out.It pumps tires quickly and there’s a nice illuminated pressure indicator showing current air pressure in the tire you’re filling. Once you let off the fill trigger, it stabilize at the current air pressure.My only gripe is that the trigger is oversized and almost every time I use it, I bump the trigger causing the thing to go off. It’s annoying.It’s too early to talk about battery life b/c I just got it but I’ll update that later here.Unfortunately, the nozzle doesn’t fit on presta bike tire valves but the pump came with adapters so it works but it’s a bother to have to connect an adapter before using on any of my bikes.It’s a bit loud but that’s not a big deal.Mostly, it’s a simple device that works well.I’m happy to have it.

    I have to admit that I didn’t expect much, but was totally surprised! This thing just flat out works! Bike tires, inflatable, car tires and truck tires are no match for this thing. It gets tired if you have to add to all four tires, but who wouldn’t? Let it rest and it’s right back to work! Taking one truck tire from 40 psi up to 86 psi was not a problem! Accuracy is pretty good as you need to inflate to about a pound and a half higher than your desired psi, then stop inflating, then check the pressure again. Then it will be spot on. I always hated dragging the small compressor out to do one tire, but this thing makes it so easy!

    What I love about it is its portable and easy to use.I already own a 20 gallon, a 5 gallon, and a portable compressor that came with my car, but I drive e on under inflated tires chronically. It cost more in fuel and tire replacement every year.Why, when I own several compressors? Because they aren’t convenient to use. And I’m super lazy!So this is the lazy-man way to go about it. So easy, I have my daughters doing their own tires too, and they don’t even remember how to check their oil.Great product, and I already own 8-10 other ryobi tools, so it’s a no-brainer.

    Just the thing for topping off tires, or putting a few pounds in a tire that has a slow rim leak. Accuracy is like any other digital gauge: consistent number but not necessarily in line with what your vehicle will show from tire sensors or what you will get from a cheap $1 air pressure gauge. For example, from the Ryobi I get a reading of 35 pounds air pressure, but the vehicle sensors say 33. At least it gives me a clue. I just adjust accordingly.You will love how easy this is to use. I hate plugging 12-volt devices into the car, worrying about the cord getting caught in the door hinges, not having a long enough cord, etc. This is quick and easy. I use a 2 amp-hour battery on it, and I have been able to top off all tires on two vehicles without running out of battery. Not sure how a major filling job would drain battery, but not worried!

  7. SoCal Hiker and Prospector

    Main use is to have this pump in my car and fill tires as needed. it’s handy since it’s battery powered, and uses batteries I already have. It’s very lightweight, so it should be usable by any adult.The one thing that I did notice, is that since it is lightweight and relatively small. It will overheat easily. Just topping off 4 tires with one low on air caused the device to heat up quite a bit. Too much heat will cause the compressor to fail. So I’d say this compressor is more suited for light duty. Inflatables like rafts. To light car tire duty. Topping off. Hitting one tire that needs a fill. I don’t think this would be able to handle heavier duties like filling an entire tire from empty. Or filling a larger truck tire. If you are forced to use in heavier duty situations, I’d be very attentive to the temperature of the device and make sure to let it cool down if getting hot, instead of pushing it to get the job done quick.

    I use it to inflate the tires on my riding mower and my garden wagons. Works perfectly – very portable, easy to use, and goes a long time on one battery charge (I inflated a mower tire with a slow leak probably about 20 times on a battery that was already down to only one bar, so it uses very little juice). No complaints. I love all the ryobi products I’ve had so far. One thing with the gauge, it does show a different reading when you’re actively pumping vs when you let up on the button. I’m assuming the reading it drops to when you’re not pumping is the actual pressure, so I always go a little over and then let up on the button to see what it reads. I’m not sure if that’s the correct way to do it – instructions might be better to mention that. But it gets the job done.

    This review is for the “Ryobi Portable Power Inflator for Tires [NEW DIGITAL GAUGE] [18-Volt] [Cordless] [ONE+ Battery system] [P737D]” tire inflator ($32.87).So far, it works great. I’ve used it to top off the air on my motorcycle (R1200GS) and cars (Explorer and E300). Like others commented, the digital gauge is not accurate when the pump is running. The noise is acceptable, and the hose is long and flexible enough.The biggested benefit of this product is the easy of use. Just put a battery in and inflate anyway. Much easier than any of those 12v portable inflators that you can buy everywhere. Definitely more convenient than having to go to the gas station and telling the attendant that by law they have to turn the thing on instead of extorting you for 50 cents.Some comments mention poor quality resulting in a short life, but so far I’ve had no issues. If the thing ends up breaking, I’ll update my review.

    Since I already had a Ryobi product (drill/screwdriver), I already had a battery pack. I did not need to buy another product and double pay for another battery. Also, I did not want to deal with electric wires from plugging an air compressor into the dash power source. So I bought the Ryobi Portable Power Inflator. (BNI – Battery Not Included) Now there are other products out there that are bigger, that have a larger piston for air compression, but I have found that the Ryobi is perfectly adequate for my car tires. Just make sure you have a tight seal, nozzle to tire valve, and it inflates easily without overheating or jamming (as other purchasers have reported). Further, the digital tire pressure readout is accurate – not while it is filling but when you release the trigger. I fill two lbs over the desired pressure (i.e., 35 psi for a 33 psi optimum) and when I release the nozzle, I get about a 2 lb bleed off—great product for the price point. I am pleased with this purchase.
