Ryobi 18V Cordless 1-Gallon Air Compressor Review | P739 | Will It Work For You?
18-Volt Air Compressor - Ryobi's 18-volt line has brought forth some different and cool tools sold through Home Depot. The new Ryobi 18V Cordless 1 Gallon Air Compressor, model P739, comes to market at a great price for someone who would like to get into a small air compressor or wants a portable model. The air compressor is run off one 18-volt battery and Ryobi states it should be a 4.0Ah battery or larger for best performance. Runtime on Ryobi's cordless air compressor is pretty impressive with the compressor running 30 minutes total before the battery is discharged.
Initial pump up from 0 to 120 psi is 120 seconds and recovery time is under 27 seconds. Those times are not too bad when comparing it to other models at that same price point.
Break In
A break in procedure is very common in almost any air compressor and the Ryobi 18 volt battery operated model is not exempt. Prior to using the air compressor, charge up at least a 4.0Ah battery pack and insert it into the air compressor. Flip the unit upside down and open the quarter turn ball valve on the bottom of the tank so the air compressor cannot build pressure. Set the compressor down on a flat surface and flip the switch to on. The air pressure gauges should not read any pressure building. Allow the air compressor to run for 30 minutes or until the battery is discharged. During this period you will hear the motor tone change. That is completely normal. Once complete, your compressor is ready to be used.
Perfect for Finish Nailers
The main use for the Ryobi18 volt air compressor will be with pneumatic finish nailers. We tested the compressor to see how many shots could be fired before the tank went into recovery. With a 15 gauge nailer we could fire 7-8 shots, with a 16 gauge nailer we fired 8-9 shots and with an 18 gauge nailer we were able to fire 9-10 before the compressor would kick on. That does not sound like a lot, but what made that tolerable was the low noise from the compressor and the quick recovery rate. This is not going to be a finish contractor's main compressor, but it does provide a cordless option for completing a small job or punch list.
We know that there are many other uses for this compressor and we wanted to test a few of them out. People always ask if these small compressors would run an impact wrench. We show you it cannot. Also, for filling tires, this unit will help you gain a few PSI, but much more than that and you will find yourself filling the tire and waiting for the air compressor to recover then filling again. Great for an emergency, but not for weekly or monthly use.
Overall
The Ryobi 18V Cordless 1 Gallon Air Compressor should be priced at $99 at Home Depot. The price is very competitive when comparing this to other battery operated cordless air compressors on the market, albeit only 0.5 scfm at 90 psi.
This is one tool that we expected to be a hybrid tool allowing for it to run off a cord or via battery. While we see now that it is not needed due to the great runtime with multiple batteries, it still seems like a viable option.
PEOPLE.... ITS A 1 GALLON TANK.... How much stuff do you think this will support...?? This is NOT a 20 gallon tank to push dozens of tools or fill up 4 tires... Its 1 gallon... !!!
I am Pinning this comment. That is why we tested this in all the different tools and tasks as people think it is a dual stage 80 gallon on a battery. :)
Very much appreciated .. Just speaking how it is because most people will watch your video but not pay attention to the details .. They will watch it, see it and then ask questions when the answers were CLEARLY in the video.. !!!
People are idiots.
You're half right. Tank size has nothing to do with inflating tires. They would inflate faster if there wasn't a tank to have to pressurize in addition to the tires themselves, though at least the buffer of a tank helps to get a more accurate PSI reading for a regulator.
It claims to fill 9 tires though..
*Great **MyBest.Tools** cordless wrench a little heavy*
I am a mobile bicycle mechanic, and this would be perfect for my business. Thank you for the video.
for a guy who just got a home in need of alot of small repairs this thing has been super helpful and i also use to to clean my computers for the price and being able to fit it into smaller areas was my reasons for going with it and no regrets so far!
This unit exceeds in one place both the Dewalt and Ridgid fail: height. The others are too tall to easily stow in the plywood drawers so many contractors build in their truckbeds. As a handyman that occasionally does trim work - these small cordless compressors are a great idea.
Great review. Just the facts of what you experienced saved me from buying and needing to return. Thank You
Brian you guys do the best reviews on the web. Hands down. Thanks for the info.
Wow. Thank you!
A appreciate all of the information. Saved me time and money buying this exact item. I clearly need more to run my pin nailer for several hours
Damn ryobi is going after everything these days.i just saw the bolt cutters they have yesterday 👍
It really helps this compressor to fill a tire up when you set your regulator to about 60-65psi ...... fills the tire a lot faster than Javi g it at 120psi and then just shoot the air to the tire ... it will drain the tank in like 4-8 seconds and maybe get about 8psi increase on the tire at to having it at 60-65psi and it will drain the tank slower but the tire will get about 10-15psi increase on the tire..... just my personal testing and noticing when filling a tire on my personal vehicles since I do mild mud/track racing and constantly have to lower and increase psi .... hope it helps
Thanks. That makes since. I got one because sometimes I need air in the back yard, or away from my garage. I was going to get a carry around tank for that. The motor on this compressor doesn't seem very big in terms of volume.
Excellent review. I just picked one up for that once a year need for air outside the range of the regular compressor. I'm looking forward to it.
This works pretty well for me. I have one and it was exactly what I was looking for. I work on garbage...errr I mean RV’s, and the moldings are always falling off. The staple gun I use doesn’t come in a cordless model, so I can go out on the lot and make the repairs quickly without having to move the unit to the shop. I was hoping it would be better at filling tires tho...
I got this for dirt cheap used on facebook not long ago and hooked it up to a spare auxiliary tank so it held 6 gallons. Works great! Obviously tanks longer to fill/refill but cycles much less often on small jobs.
So i picked this up to replace tires on the OneWheel and it is pretty amazing. After my first two tires changes (that includes setting the bead and refilling the tire) the battery was still reading 100%. I changed probably 7 tire now and the battery is still not dead. Keep in mind these are go-kart tires, but i'm extremely satisfied with it.
Same!!
Great Video! I already have their P731 inflator and was going to get this but I see that the P731 is a better option. This would be a waste of money. Thank You again!!
In practicality, I'm thinking good for small/emergency trim repairs? and (more relevant to my field), blowing out blocked condensate drains.
Paid $79 at direct tools used it today I’m impressed it’s quiet surprised and filled up to 120 psi fast
Very honest review. Thank you.
Awesome review and it helps!
THANKS FOR THE INFORMATION. I've been buying Ryobi tools and so far so good. I'm looking for a compressor and wanted to check the Ryobi. It sounds like it's not ready for prime time. It's a start which I can appreciate.
Rated at 78 decibels, not loud enough to damage hearing, pretty great for a small repair / reno job with a little bit of trim nailing
This is great for people who only own pneumatic nailers and often do small carpenter work in high-rise buildings, offices or job site with no electricity. In my case I have both pneumatic and cordless nailers and if i end up in a no electric jobsite I use my inverter to run my tools.
Great overview... I was looking to buy this to attach a rotary tool to polish/restore rusted wheels, gas tank and random parts in a motorcycle. It may work for that... but now am skeptical and looking at the cost of that battery. Appreciate the review... you may have saved me some frustration and waiting my money.
great vid keep up the great content
Thank you for the info.
I like how you hooked up the air ratchet to show first hand it doesn't work with something so small! Might buy this to top off an air tank after filled in my garage by a larger compressor. Thanks for the video always learning through your channel!!
Not bad. Not for me, but not bad. Good review, guys. 😊
Thought about getting this to keep in my trunk for flat tires. Will have to look into it more now
Get an inflator for that. Not an air compressor.
I bought an "avid" air inflator for 30 on eGay . They usually go for 50-70 on Amazon but if you shop around you should find it for 30-$45
I have a Dodge RAM 2500 truck with rear "tube" type air bags. I inflate the bags when I am towing my 5th wheel. I wanted a compact, battery operated air compressor that I could keep with the trailer without taking up a lot of space. Since we have so many other Ryobi tools (with lots of batteries), I thought I'd give this one a try. After watching this video I was pretty skeptical. I inflate these bags, one at a time to 65 - 70 psi. This little unit had no problem inflating the bag to 85 lbs. (I stopped there as I wasn't sure what would happen if I went to it's max capability). However, I agree with the comments in this video that it may not be what you would want if you expect to inflate a truck tire out on the road. But, for my application I think it's going to be perfect. I hope this helps.
Thanks for the great review. With the proliferation of battery nailers, I think this unit really doesn't have much use. If you need something one step above the 'U' shaped inflator then maybe....
I just got one at Direct Tools for $44. Haven't had a chance to use it yet, but will see how it goes.
Thanks for the review Brian. I'm on the fence on this one. I have two one gallon air compressors already, a California Air Tools which you could run in a nursery (really), and a Campbell-Hausfeld which you could probably hear from your house. They were great before I switched over to battery operated finish and pin nailers, but what else can you do with a one gallon air compressor? I don't even use my large air compressors anymore because pretty much everything I own is cordless. As a side note, I try to be "green" and take care of the environment, but this is taking things to the extreme. From the Ryobi manual: "Tilt tank to drain moisture from tank into a suitable container. NOTE: Condensate is a polluting material and should be disposed of in compliance with local regulations." So where do I recycle my air compressor condensation? LOL!
Thanks for the video. What brand/model makes a hybrid version?
Really like your reviews...I think they are very fair..
Thanks Nicholas.
Thank you for the review
Your Welcome.
@workshopaddict would this be strong enough to blow out a small irrigation system? I'm talking one line with one pop up.
I definitely see the niche use potential of this, a 3 gallon hybrid version would slap though.
One of the most useful tools to have around is a blow gun just to blow dust and dirt off things or drying things off after cleaning with isopropyl. I got mine for this exact reason so I'm hoping it will do the job. Thanks for the review!
Did it work for you?
@@nukiewin Sort of. It's not great but for small parts and situations where you're willing to wait for it to repressurise, it's useful enough. I think a 25l plug-in compressor is a much more useful thing to have.
Ok, now here's a tool I don't have yet! A battery operated compressor ! And I'm on the Ryobi battery platform too ! Something to consider , but probably not something I would need since almost all my tools are now battery operated.
Best review!
I’ll tell that’s a great deal I think Ryobi really is the bang for the buck some things could be a bit better but I like all the tools I have.
I would advise anyone considering buying this new tool, get the extended warranty. Everything new that Ryobi puts out I'd recommend it!
warranty for a unit that costs around $100 ?
Good vid guys 👍
Thank you
bike tires , balls , small 14" or 15" car tires , great hobby table duster like for cleaning tvs or game consoles .. thats all i can come up with .. basically limited to small tiny jobs
If it had been a hybrid, I would have gotten one. I would love an aftermarket hybrid adapter.
So DIY. Get an old 18V NiCd battery shell, wire it up to an 18V 20A-30A AC-DC PSU which can be had on ebay/alibaba/etc for around $40. Being separate instead of built in, will make the compressor more portable when you need it to be so.
@@stinkycheese804 Plus EACH TOOL now becomes corded if you need it to be . things Like the Vacs would benefit from that. Problem is, some of these tools Demand 30+ amps. that's not that easy. some tools. Particularly the newer ones (Brushless mostly) use 1k to 1300 watts.
I have the 18v 1+ impact gun I keep in the truck and can see this also in the truck with a separate tank to fill for tires.
What corded inflator would you recommend for home use for filling your car tires?
Omg this would be perfect for airbrushing
would you recommend this as small workshop compressor to blast dust of tools ?
Quick question - Can you use this portable compressor for your Bendpak lift? I would assume so since it only needs 30psi to release the locks.
I saw this at Home Depot and was wondering if it would work for me. It wont! Thanks for the review.
3:12 Minor note. You say that it takes 120 seconds to build to 120 PSI pressure, but on your phone it shows 1 minute, 20 seconds which is only 80 seconds.
Hi can you use this to spray cars. I mean like spraying car mirror casing light work.
Perfect for airbrushing
Can you recommend a brass replacement for the plastic outlet tip?
I have a 4 CFM LVLP spray gun and iwata airbrush gun. You think it'll hold up on small spot repairs on rims / wheels?
mine is on the way back to HD. thanks for the info it really help and will save me $. good thing that i haven't open yet. the ryobi digital inflator will be beter around the house. ; )
It screams out for a 120V cord. It should be able to drive a framing nailer, one nail every minute though. Need a cordless coffee maker and cordless generator next.
Certainly not for everybody, but there are definitely advantages to and times having a mobile compressor unit to achieve, regulate and deliver high PSI would be helpful... though personally this would never be my setup of choice I imagine a larger slave tank could also used... this seems geared for farm or mobile repairs where for whatever reason not even 12v might be available.
will this compressor work if I attach this to a texture hopper for small drywall patches?
You could probably add another tank for extra volume good for airbrushing or cleaning your car or unblocking bathroom sink and minor home quick fix
Would you recommend this for a paint gun?
Probably OK for Airbrush work ?? ( up to 40 psi @ 0.8 cfm ) Noise level ?
Good for a smoke machine for diagnosing leaks?
Airbrush. 25psi max. Sounds pretty quiet. Might work?
What would you use to use for car tires?
Will this compressor work with my porter nail guns? What else will I use compressor for besides nail gun?
Would it work for a framing nailer? Thanks
Good review. Seems like all its good for is stapling or nailing pieces of wood together. Unfortunate that it can't inflate tires properly.
Nice video interesting
After the 30 min break in close the valve & keep it on?
Would this be great for detailing cars
Can I assume that you cannot run framing nailers with this?
I have a small 1 Gallon Senco compressor for finish work. Used it for a decade with very few issues. I'm sure this Ryobi compressor would work okay too. But you always have to factor in the cost and wear and tear on the batteries for something like this, and ask yourself, "Does this REALLY need to be cordless? Does making it cordless give me any real advantage VS having a cord?" Since you're talking about dragging a hose around with this thing anyway, I can't see using it for regular jobs as your main trim-nailer compressor. Maybe a backup compressor, but I have to question whether it's up to the task to be used continuously as a main compressor. I suppose this would be handy if you happen to have it and find yourself needing to drive some finish nails somewhere where there isn't an outlet nearby, but how often is that? I have some weird tools for Ryobi batteries, but this won't be one of them. It's cool that they make it, but I can't see ever needing it. Maybe hanging some crown moulding during a blackout? Installing quarter-round in a remote cabin? Driving through Amish country, stopping in front a Jebidiah's house to build a bookcase real quick and make him jealous?
Thanks for the truthfulness about this. I think it’s a waste of money.
I have found that it will fill the tank 15 1/2 times with a 4 ah battery only giving it 2 minutes to cool
Very neat..... now send the idea to Milwaukee 🤔
James S Milwaukee owns Ryobe or the other way around, not sure who owns who but they are the same company, along with Rigid. All are owned by TTI.
@@chriswebb3018 He knows
Mine wont fill past 30 psi, even with nothing attached, nothing seems to be leaking, any tips?
Seems ideal for bike assembly.
I liked the idea of this until I saw the price. For $129 without the battery, you can get a very good 6 or 9 gallon air compressor. I spent $40 on a 3 gallon from harbor freight and it runs fine.
lol, i love it when someone recently buys a semi-complex HF tool and states it works fine. Come back in a few years and tell us the cost per hour till failure, and how FREAKING LOUD IT IS. Yes I was yelling. It's that loud. Otherwise I agree, in cases where you don't need it portable, AC powered is the way to go, far larger bang for buck and typically much higher airflow per dollar too. IMO Ryobi sized this just a little too small for the target market, for it to be the largest they offer at least. Even if they stayed at 1.5gal tank for portability, a little larger motor and cylinder could have still been portable size and weight for the average healthy person doing the sort of work with it one does.
Try using it out in the middle of the desert with no electric outlet!
@@bryanpatrick7272 you can if you have a generator
Ok ---Now we are talking about a 500 dollar generator (to go with you compressor), a gas container & gas, to power your HF air compressor. Stick it behind the seat of your SUV with the kids and everything else you have just to air up a tire----wonderful! lol ---I'll keep my Ryobi, 1 gallon tank, battery power pack, thank you very much.
Thanks for the review. It was good to find out that this is not the air compressor for at home tires. Now I am wondering what air compressor I should get. I am very concerned about safety because I am a lightweight, wussy tool user. i just ordered a Milton S-568 air inflator and need a suitable air compressor. My dad used to take care of my tires, but now that he is dead I am needing to grow up. The cheapy tire inflators that come with the compressors built in were getting such bad reviews that I figured I would do better to get a good inflator with a nice portable compressor. My dad had a Central Pneumatic compressor in the garage that was all ripped up. It seemed to have some fluid in it, and I noticed a note on the side about draining it regularly so that it wouldn't blow up. Eegads! I don't want an air compressor that could blow up. We also had a friend of the family lose the tip of one of his fingers on an air compressor from it starting up when his hand was in the wrong place. So I want something safe, but that will have enough pressure that I won't be spending half the day just to inflate my tires. It's always so cold when the tires need extra air. If anyone has a recommendation of what would be good for someone who wants safety and not to have to spend all day in the cold just to maintenance my tires, I'd appreciate recommendations. I won't be using the compressor for nails or staples. Maybe occasionally I might use it to blow some air on the ground, but mainly just for tires. But if paying extra is what I need to do it right, I consider this a long term investment. I don't want to screw around with crappy products that die every two years or that make things any harder or longer than they normally are because I hate messing with tires. Don't want something I am going to have to drain fluids on or where there is just as much maintenance for the compressor as there is the silly tires. Thanks for any help!
@bennyblanco Hello, thanks for your note. Yeah, I bought a Bostitch pancake compressor. It's noisy as hell and kind of a maintenance hassle, but it seems to do the job I wanted it for. I don't think I would recommend it as an ideal compressor to anyone, but I also don't feel I need to replace it. It's working ok. :) Thanks again!
What size fitting for the hose? 1/4?
I'm gonna try this with my adapter and 12ah Milwaukee battery
Let us know how that works please!!!!!
Did it work?
You have an adapter to use other batteries with ryobi tools?????
@@cpeterson877 yes, along with adapters for rigid, Makita, dewalt etc I never purchased the air compressor, but I run m18 on my ryobi lawnmower and my ryobi weed wacker. There's adapters for makita , dewalt to ryobi...search ebay
How would this work to use with an air blower? I’m wondering if I could use it to take to apartment units and clean out refrigerator coils.
Works great for very short periods of time. like 10 seconds
Never blow off coils in an apartment. Always ALWAYS vacuum.
I have been eye balling it, my question is how well does it handle an airbrush? Is it useable or does it burn though the gallon of air in a few seconds. I am talking painting models not walls.
What PSI are you running and do you know the scfm of the airbrush?
3:18 Not 120 seconds... That was only 80 seconds or 1 minute 20 seconds.
Yes, My mistake. I am constantly reminded and sorry.
I would love this for a tire but those cfm need to be higher and I should be able to run it connected to 12v if available.
18V is more powerful, you just need a larger 18 volt battery.
Im going to see how it runs a framing nailer. Stay tuned for update. . . Maybe
Can I use this with a critter paint sprayer?
Nice review Brian. #WORKSHOPADDICT
Can I use the 18 v battery on my beer opener
I used kzhead.infoUgkx4ynqaujg7rZKFapA8s29kTpRszJGa3-K this for the first time today to replace the front wheel bearing on my rwd 98 dodge dakota. This had absolutely no issue removing or reinstalling the lug nuts and it took off the axle nut without any struggle. Sounds like it's got some muscle to it. Time will tell
A backpack version of this would be so cool since Ryobi won't make a Lithium Ion Battery Powered Roofing Nail Gun!
Heh, wearing a heavy backpack on a roof, with an air hose tangled around your legs no less. What could possibly go wrong?
What about light airbrushing?
I wish it had a outlet for DC
How long could I run an airbrush at 30 psi off a 6 ah battery (approximately)? Thank you in advance and thank you for a great review.
What scfm is your airbrush?
Perfect for my air horn
Might be. Let us know.
The ryobi 18v 18g and 15g nailers run all day without a compressor, if that what’s you want and don’t want to lug around this compressor and wait for filling up the small tank.
Could be a dumb question, but thats the fitting for the hose? Like what fitment do I have to buy the hose in to plug it into the air compressor?
1/4” quickie
I’m looking for something with enough power to blow myself. I do lawn service and get grass on me after every lawn. When I go to give quotes I have to drive to the car wash to air myself and equipment off then head to give the quote or when I am done at the end of the day I like to blow myself off and equipment before going home. Don’t like taking all those grass clippings home. Would this work good for that?
Too small of tank. You might get 10 seconds of air with a nozzle.
@@WorkshopAddict oh ok. Yes that’s what it seemed like after watching your video. I need something stronger. Ok I’ll have to just go with another compressor then thanks
