Why You Should Choose Ryobi P739?
“Time is Money” as the Quote speaks itself… What’s really important is to save your time and money. So, following the quote, I am giving you “My Personal Recommendation” on the best cordless air compressor. Based on our deep analysis, and hard research, the Ryobi P739 Cordless Air Compressor is overall best due to its warranty and the cheapest price. Plus, all the features are best suited for small jobs and tools.
Previously, I talked about the famous cordless tire inflators and I think this will be the 2nd and final part of our conversation. For the most part of my research, I have seen a lot of confusion about this issue.
Many people just mix up a cordless air compressor with a cordless tire inflator. But, the single thing that relates them to each other is the “Cordless Aspect”.
While the rest of the features of cordless air compressors are way higher than the best cordless tire inflators out there in the market.
This means they’re powerful, durable, more enduring, than a typical tire inflator. Plus, they are battery-operated and don’t need the extension wire to run.
Whereas the extension wire mostly limits your portability and movement within different job sites.
Rule of Thumb!
Remember! that these buds are specially designed for low-profile tasks and quick repairs. You can’t put a heavy burden on them. If you did then the only thing you’re gonna get is dead weight.
So, I stack up this buyer’s guide for the best cordless air compressor for 2021. The guide will clear up most of your confusion. So, let’s begin and end our previously continued talk…
Best Battery Powered Air Compressor 2021 [Buying Guide]
Below are some of the critical factors you always need to look for when choosing the best cordless air compressor. Whether it’s your visit to the physical store or you’re on your PC buying online. The buyer’s guide works for both types.
You are well aware of what does PSI stands for and what does it relate to? But to just refresh your knowledge, I will rephrase again in fewer words.
Pressure in pounds acted on the area of a square inch is termed as PSI. Higher PSI ratings mean a greater amount of compressed air is available to air-tool to perform heavy-duty jobs.
Cordless air compressors are the junior buddies and focus on portability. Thus they have a small reservoir of the tank. Yet, the tank size is enough to entertain small-level tasks conveniently.
Battery Charging and Backup
Whenever you go with a product on batteries, you need to know some common yet important factors related to batteries. And these are:
Factors Related To Battery
- Battery Type
- Power Ratings
- Battery Life
I’ll define each in few simple words for you. Another important factor is the power ratings of the battery which include battery voltage and Ah.
Battery Voltage and Ampere
Ah is short for ampere-hour and it is the current in amperes that can be supplied to the tool in one hour. This rating is related to the battery backup also.
Therefore, a greater Ah rating will have an extended time of backup by the battery. You can have more time for backup for doing your tasks. This is actually the prime factor of your interest while buying the product.
The battery charging is related to the battery voltage and its rated current. The charging circuit should be powerful enough to accommodate both for ideal charging.
Multiple factors can affect battery life such as overloading, overheating, and overcharging. You must take care of all these for a longer lifespan to avoid possible damage or malfunctioning.
Let me sum-up up the batteries in the end. As the batteries are pre-installed, so you don’t need to worry about some of the above-said factors like type, rating, and charging.
Types of Batteries
Do you know that batteries come in different types? Such as Li-ion, Ni-Cd, NiMH, and more. You have to select the right one according to your application, like for cordless air compressors we use Li-ion batteries.
For better tool operation, fully charge the battery before using it and replace the faulty one whenever needed. All you need is to take care of your battery and avoid conditions that lower the life of the battery.
The cordless in the name also implies the portability factor. Thus, cordless compressors are smart and compact. They occupy less space and are low-weight products.
You can easily place them and conveniently transport them anywhere within the worksite or to other job locations.
Price and Warranty
Cordless compressors with their great portability features are not much costlier. They are user-friendly in terms of easy operation and pocket-friendly from the budget point of view.

Ryobi Cordless Air Compressor ONE+ 18-Volt [Best Cheapest Battery Powered Air Compressor]
4.8 / 5.0
Ryobi 18-volt one+ cordless compressor is the recent addition to the world’s largest 18V tools system. It is built to deliver up to 120 PSI, which is perfect for roadside tire inflation and smoothly running up the finish nailers.
This cordless compressor comes with a tank storage capacity of 1 gallon. That is suitable for running up small tools or doing lightweight jobs around the home, garage, or shop.
It efficiently works with the Ryobi battery system with different ranges of Amps.
For example when using a P108 4.0 Ah LITHIUM+ Battery. It can inflate 9 car tires per charge.
But, here’s an advice from me due to what I have seen…
Ryobi 18 volt one+
What I have seen is that this18-volt one+ cordless compressor is a power-hungry beast. So, it’s better to use a 6Ah 18V Battery One+ battery. Or otherwise, this small beast will gonna suck all the battery if you’re using 4.0Ah.
There is a push-to-connect quick coupler that helps in quicker inflation with a single-hand operation. In this way, you can quickly connect or disconnect the air hose.
On the air outlet, you can use the Milton red coupler fitting for quick disconnect. The air hose it supports is 1/4″ with its own plug and coupler. But, a 3/8″ coiled hose with a standard industrial quick-release coupler also gets the job done.
The intelligent lock-on regulator system helps in setting the intended PSI pressure. Thus, the PSI remains stable and doesn’t fluctuate (get’s too low or too high from the intended PSI) due to any problems.
As for the body, it is built with a durable metal casing with onboard storage wrap. The casing not only helps in storing the air hose but, also protects the cordless compressor from a rough job site environment.
It has a lightweight design of 15.27 lbs that gives portability to users in moving from one place to another. Plus, the rubber mold on the handle grants comfort and firm grip to the hand.
Now, for the warranty, the Ryobi has sealed the deal with the 3 years manufacturer’s warranty. While on the flip side of the coin, it’s the cheapest cordless air compressor of all.
- Cheapest of all
- 3 years warranty
- Good in winters for RV water lines
- Highly portable due to lowest weight
- Supports truck and farm tire inflation
- Smoothly runs small staple-gun or brad nailer
- Lock-on regulator for setting-up intended PSI
- Simultaneously pumps up 2 truck tires per charge
- Durable metal casing with onboard hose storage wrap
- Built for small tasks and tools
- 1 report of pressure fluctuations during nailing
- No battery, charger, air hose, and coupler fitting
Milwaukee Cordless Air Compressor 2840-20, 2 Gallon [Best Rechargeable Air Compressor With Highest Warranty]
4.8 / 5.0
Milwaukee 2840-20 is also the recent release by the RED Giant. It comes with 135 Max PSI and a 2-gallon tank storage capacity. That is best suited for inflating car tires, running airbrushes, and nailers with nails of any size.
It is the quietest cordless air compressor equipped with a 68 dB noise level that gives a silent working environment. You don’t have to keep your distance or attach extra hoses just to avoid noise. That’s why it has become a perfect choice for carpenters, remodelers, DIYers, home, and shop owners.
The lightweight design of 31.2 lbs makes it extremely portable to carry and move around in the same area or to others as well.
While the compact rectangular metal frame makes the compressor more stackable to store into any garage corner or in your car as well.
So, I was also seeing that the frame does have 4 extended bases on which the compressor stands.
But, the metal frame base doesn’t have any rubber feet…
My Advice To You
So, my advice to you is to install 4 extra small rubber feet that can support the compressor frame. In this way, the compressor will be protected from scratches which can later lead to rust and wear.
This small beast supports the “REDLITHIUM Technology” and can run on different capacities of batteries. The unique thing is the nailing amount depends on the “Ah capacity” of the battery.
Not only this type of extraordinary battery system gives faster and fewer recharges.
But, also grants high performance, more power, and longer compressor runtime for different power tools.
I think all power and performance the Milwaukee cordless air compressor gives is awesome. But, the 5 years warranty makes it more worthy than a jewel for garage, and shop folks like you and us.
Finally, the price… Hmm! My opinion is that “it is moderately expensive”. Plus, all the features it comes with are really worth that much cash.
- 5-Years Limited Warranty
- A quieter sound level of 68 dB
- Extremely quicker delivery service
- Good for dry patching, texture spraying jobs
- Lightweight, portable design with high output
- Supports up to batteries with different capacities

TC-BL Cordless Portable Air Compressor [Best Digital Cordless Air Compressor With AC/DC/Li-Ion Support]
3.0 / 5.0
As I have seen myself, the TC-BL is the newest of all in cordless air compressors. The unique thing about these cordless compressors is the “3-Mode Supply System”. That means they can be run with DC (12v to 30v), AC (110v), and of course with a Lithium battery.
TC·BL portable air compressor has another unique thing regarding the battery which is compatibility. Yup! this mate is compatible with Dewalt, Makita, and Milwaukee Batteries as well.
The fantastic thing about this small dude is its 2.5 SCFM @ 90 PSI, 130 Max PSI pressure, and the heavy-duty dual aluminum cylinder. That holds a 5-liter capacity for a quick recovery time.
The motor is made oil-free to avoid excessive maintenance chores. Plus, the compressor has two speed modes i.e., high and low mode. The high-speed mode runs with a noise level of 75 dB while the low-speed mode runs at 60 dB. That’s quite intriguing that a compressor has two noise levels suited for every type of environment.

My Personal Recommendation
Well, let’s get down to the end of our discussion. Seeing the statistics and comparing all the features I say Ryobi Battery Powered Air Compressor takes my recommendation.
The important things it has are the warranty and the cheapest price. Plus, all the features are best suited for small jobs and tools. There are some minor issues like battery, charger, hose kit was missing. But, most of them I have already covered.
But, if I have to choose a bit more power then Milwaukee is the best shot I have got. More power, performance, and storage capacity. Plus, the 5 years warranty and multi-type battery support really pack a punch.
You know It’s a bit bulkier, and the nozzle kit is not included. But, that’s a far cry because you can use your own air hose kit. In my opinion, the Estwing or Flexvolt works fine with almost all air compressors.
As for the “DeWalt Cordless Air Compressor”. I think it is expensive but, on the other hand, the raw power it holds can do much more than other cordless compressors. Not to mention the battery and charger kit come along with it. Over time, few issues have come up with it which I already discussed with you…
The Freeman PE20V1GCK is kind of similar to Ryobi in few aspects. It’s a good compressor with fast delivery support and there is a 1-year limited warranty. Another great thing is the battery and charger are included in it.
Finally, for TC-BL and Ridgid, the TC-BL is fairly new in the market. But, there are critical issues with it and also there is no warranty. On the other side, Ridgid… I don’t recommend it due to the “Refurbished Condition”.
So, for me is Ryobi and what will you choose…
Best Cordless Air Compressor FAQs
Q: What does cordless air compressor mean?
Ans: The cordless air compressors are specially designed compressors for small tasks and jobs. They are the “Hybrid” of tire inflators and fully-fledged air compressors. Meaning they operate on battery without any wire and, can do tasks that tire inflators can’t do.
Q: Are cordless compressors any good?
Ans: Yup! they are extremely portable and can be stored in small corners and in cars as well despite being a compressor. While on the other hand, they are cordless and work on battery same as tire inflators but, cover up more small tasks than inflators themselves.
