Power converter are integrated in compressor.this is a hpa pump that doesn’t need a transformer for wall outlet use,safer to use.SMACO scuba tank compressor can be powered by the 12V car battery, also can be powered by the home 110V/220V AC.This will make this air pumb more usefull as you can use it anywhere.


The filling of a pcp or paintball air gun is hassle-free. The Maximum work pressure of this air compressor is 4500Psi/30Mpa/300Bar. Two pointers in the pressure gauge, one for the real-time pressure, another one is used to set pressure. You just need to set a inflation pressure, and the machine will automatically stop filling when the preset air pressure is reached.


SMACO pcp air compressor is added built-in high-power fans, no need for an external water pump to cool. In addition, it is also equipped with an oil-water separator ,the 5μm fiber and active carbon combined filter element can effectively filter moisture and other contaminants in the air, output clean and dry high-pressure air.


Under work voltage(12V DC or 110/220V AC), the engine speed can reach up to 2700r/min, and the air output is 11L/min. Our test results followed: for 0.5L container from 0Psi to 3000Psi, it spent 11 mins; for 1L container from 0Psi to 3000Psi, it spent 26 mins; for 2L container from 0Psi to 3000Psi, it spent 46 mins.


This high pressure air pump only weight for 24.8 lbs, and the size is: 9.6*5.6*10 in, it’s easy for carry around.
(Note: after the inflation stops halfway,please release the pressure first and then start again, The duty cycle of the machine is 25 minutes run / 10 minutes cool)


This air compressor can be powered by the 12V DC car battery or powered by 110V-220V at home, it has a built-in inverter voltage conversion device, you can easily adjust it from 110V-220V AC with the user’s normal. Note: the initial setting is for 110V AC at home. The inflatable interface’s diameter is 8mm, which compatibles with most of the air gun/ paintball/scuba tank.

    Nice quality product – Works great with our 1L scuba tank!

  2. Edgar Villegas (verified owner)

    Oddly, the best pump I’ve ever owned (thus far 115 fills) I wanted the ability to use it in the field, with my vehicles, and take advantage of the portability, and I have not regretted it.

  3. Jesse Black (verified owner)

    Quick and easy to set up. The auto shutoff worked as advertised. It was slow, and loud, but it worked and that’s all I care about. I filled up my PCP air rifle 480 cc carbon fiber bottle to 250 bar. It took several minutes (sorry, didn’t time it) to fill the bottle.

  4. Laramie Jordan (verified owner)

    Not to heavy and it’s mostly quiet…ive had one that’s quieter but it was also 3 times as much and 3 times as heavy… for the money its pretty great….not as a fast as my big one….but for you guys out there hand pumping, I suggest you get one of these, you will thank yourself

    Works like a champ, takes about 3mins to fill my Sig Sauer MCX Virtus .22cal PCP Air Rifle. NOT for large air tanks, but works well for the tank that comes with the gun.

  6. Hemi (verified owner)

    Works great for 1 L. Having said that before you get into this game, get certified and wholeheartedly enjoy yourself. If not you may have a very bad day. Just saying!

    This HPA air compressor is one of the greatest investments you can make when running HPA powered paintball markers. One of the biggest pros to having an HPA marker is the ability to self-fill the tank but without a good quality PCP compressor, you’ll have to resort to driving out to your local paintball field and getting it filled there. And some places even charge you to fill your tanks! This compressor not only equips you to fill your HPA tanks at home but also on the go via your car’s battery.
    The air compressor comes with everything that you need to get started. From wrenchs to extra anti-explosion diaphragms. You can go from box to pumping up air tanks in 5 minutes and that even includes filling the tanks. Everything was nice and secure in the box as well so I was confident things didn’t get dinged up. The unit itself is pretty compact to the point where you can transport 2 of these things in your car trunk and have space for groceries.
    The first time trying this thing I have a couple of things to point out, especially if this is your first PCP air compressor. First off, when you use this air compressor for the first time it might seem like it’s loud but compared to other air compressors this thing is relatively silent especially if there’s a wall separating you and the air compressor. The sound produced from this compressor is less of a thumping noise but rather the whine coming from the fans which are cooling the whole thing. The process to fill up one of my 48ci tanks was very simple. First, make sure that you have the switch located under the rubber piece at the top of the compressor is selected to your appropriate house voltage, toggle the 3 stages red switch to the same voltage and once that’s done you’re ready to hook up your air compressor to your HPA tank. Please make sure to use the water and oil separator since this will reduce the chance of failure and moisture getting into your air tank. Make sure to read the instructions if it’s your first time, you don’t want to make any mistakes that’ll cost you.
    For my test, I only pumped it up to 1000 psi since I didn’t plan on using the tank any time soon. It took about 5 minutes to pump my 48ci tank up to 1000 psi using wall power. Once it hit my set psi it automatically shut the pump but remember you don’t want to unplug it immediately. It’s important to keep it on for some time so the fans can cool it down.
    Overall the unit is compact, relatively quiet, and right when you get it you’re ready to get pumping either at home or via your car’s battery. This thing is not cheap but in the long run, it will pay itself off.

    I have a big one as Omega and a cheap small one for using on the field. Now, this one can be perfect as a medium size if I want to pick either one for my need. When I start the hobby of air gun, I know I have to invest for a compressor instead of hand pump. It is really helpful that I am a member of few air guns forum, collecting the experience from all difference air-gunners is a plus. Some types of PCP air compressors were too loud, some too slow, some too messy with oil or water and most were all too bulky and too heavy. Add up all those negatives and I can understand why most people are not happy to pay for any of those. This one is okay for medium size with nice design. No water hassles and no oil hassle because it has built in fans to cool it. Supposedly not too loud but it is still loud as my Omega. The instructions were also good and easy to understand. All the tools and small supplies came with the unit which was nice additions. I can keep everything together and know that I have all the tools if needed. I only run mine for 15 to 20 minutes at a session. Then I let it cool down for 10 to 15 minutes just be in the safe side. This one can either run by outlet plug in or my car. If I want to use my car, I have to make sure my car is on before plug this one in so I won’t walk home because my car will out of battery if I am not. The grease in an applicator and two threaded plugs that I unscrew to put a bit of heavy grease on moving parts when the time comes. The compressor comes pre-greased, so I just plug and play upon receipt. Max pressure is 300 BAR/4500 psi, but I will never go further than 4000 psi. It works like a champ for me.

    Nice air compressor for PCP/paintball.
    With the option of plugging in to a standard 120v outlet, 240v or using the clamps for 12v direct, this thing offers tremendous flexibility for use on site at the field to replenish paintball CO2 tanks without any issues.

    Save yourself trips to the paintball field to get refills. Endless pressure on hand!
    This little pump is kind of loud, but it’s so easy to use. First off make sure your tank can be used with high pressure air and not just a nitrogen tank. I barely ever use my paintball gun, but when it leaks down or I use it I end up going for months waiting to get around to a paintball field to get my tank refilled.

    Having this little pump on hand saves me from that hassle…Very cool to be able to pump to such a high PSI from such a compact unit.

    Having this little pump on hand saves me from that hassle…There’s a plastic cover near the handle, take that off and make sure your voltage is correctly set to 115V for the US, connect your pressure line, install your water separator on the pressure line and connect your tank, plug the unit into the wall and you’ll hear the cooling fan start running, from here you set your desired pressure with the center arrow, and his the green start button on the front, once you hit that start the pump is providing pressure, tighten the bleed screw and sit around for the 30 minutes it takes for this to fill you to approx 3000psi. Once it hits the pressure you set the pump shuts off and starts bleeding down from lack of pressure, but your tank will be correctly filled. From here you just make sure the pump is set to off, allow the cooling fan to run for a few minutes to cool off the pump and then simply shut off the machine. Unscrew your bleed pressure valve and that releaves pressure from the pump pressure line ( your tnak will remain full ), then disconnect your tank and get to shooting. Very cool to be able to pump to such a high PSI from such a compact unit.

    Works as advertised. Very happy with this purchase. Using to refill my 1.5L tank, which I use to refill the little integrated tank on my .22 pellet air gun. NO MORE reliance on local scuba stores.

  13. Dusty Trails (verified owner)

    Does it’s job and does it well.
    Let me start by saying, I have never used a pump like this, so I have nothing to compare it to. That being said, I ordered this based on the reviews and price. The pump was well packed and arrived in good condition. Very easy to assemble, and was up and running in no time. Instructions were easily understood. This pump works much better than the hand pump I have used for years! Can’t say how many years of service I will get out of it, but at this point I will give it 5 stars. It does what it says it is supposed to do, and I am very pleased with its performance.

  14. Veteran (verified owner)

    Excellent quality and performance. Reliable and top performer compared to others. Look no further, this is for serious PCP shooters.
    Aim small, miss small.

  15. Bruce (verified owner)

    I like it. Nice piece of equipment only messed with it a little but as long as it holds up and fills my tanks reliable I’d say it’s a great buy e sd specially since where iim located its about impossible to find anywhere to fill em just being able to do it at home is a huge relief sd so far so good

  16. Sandra (verified owner)

    Fills my 400 ml Airforce pellet gun tank in about 2 minutes.

  17. Law (verified owner)

    Find it to work very well. I look forward to using it to fill a small SCUBA style tank and more guns in the future. What made be buy the extra water filters was test filling on a nearly expired tank. I had noticed water in the fill nipple. The humidity in my basement where i run this varies around 50%.

  18. Jaime (verified owner)

    I like the small portable size. Fills a gun respectfully but you do want water oil separator. Wasn’t as noisy as I expected. I’m pleased so far.

    I am using this to fill paintball tanks and I have no complaints.
    Hook it up and turn it on, that simple.
    I have used it to fill my tank approximately 20 times and it is still going strong with no issues.
    Overall I am pleased.

    Der Kompressor ist super, vor allem, da er ohne Öl und ohne Wasserkühlung funktioniert. ISt ideal für die Minitauchflaschen sowie für Luftgewehre.
    Hatte zuvor einen Wassergekühlten Chinakompressor, der ordentlich Öl in die Filter geblasen hatte. Hier nichts auch in der Minitauchflasche, saubere Luft ohne Ölgeschmack.
    Empfehle trotzdem noch einen Vorfilter davor zu schalten, für alle Fälle.
    Ist auch eher leise im vergleich zu dem China Kompressor.
    Der Raum stinkt auch nicht nach Öl mit diesem Kompressor.

    Bin sehr zufrieden.

  22. Pierre Shelton (verified owner)

    Upon arrival, the fans would come on, but compressor would not. Being pretty good at fixing things, I opted to make repairs here instead of sending it back. Was a easy fix as the electric motor power wire had become disconnected during shipping. I reconnected it, and she works like a champ! Beats a hand pump all to heck. Well satisfied, and recommend to all PCP shooters.

  23. Jody Castillo (verified owner)

    I have refilled my 1liter and 2liter mini dive tanks here in Kona, Hawaii over 60 times with this pump. Works perfect every time. It takes 22 minutes to fill the 1 liter tank to 3000psi and 44 minutes to fill the 2 liter tank. I only run the pump for 15 minutes at a time then let it fan cool for 5 minutes before pumping again. After tanks are full I then run the pump for 15 seconds to blow moisture out of the line. The pump is maintenance free and fairly quiet. Highly recommend this product.

  24. Vernon C. (verified owner)

    So far so good. I like it and it does the job filling my PCP rifle. I use it often. Much better than the crappy Hatsan I bought.

  25. Jack Hill (verified owner)

    There’s nothing better on the market then this thing. It works great for filling up my pcp rifles. Fast and easy to use.

  26. Bow (verified owner)

    Compact, light, and quiet. No issues filling small air rifle tanks but id only run it for about 10 minute intervals so it doesn’t get too hot and will cool down in less than 5 minutes. Usally about 2 sessions would top off my 580cc to 4500psi. Only wish this unit was designed to fill larger bottles too.

    Der Kompressor wurde binnen 48 Stunden aus Frankreich geliefert.
    Gut verpackt, doppelt in Karton und in Styropor.
    Anleitung in vielen Sprachen, darunter auch in Deutsch mit gut erklärten Bildern.
    Er verbraucht mehr Watt, als angegeben.
    Aufpusten von ca. 1000 auf 2000 Psi bei einer 2L Flasche braucht ca. 12 Minuten. Lautstärke im Abstand von 5cm zum Gerät liegt bei 75 Dezibel.. 66 dB bei 2m Entfernung (nur mit Handy App gemessen).
    Er rüttelt ein wenig (siehe Video).
    Übermäßiger Geruch beim Betrieb (wie sonst bei chin. Geräten) war nicht festzustellen. Er war bereits auf 220V bei mir eingestellt.
    Werkzeug, Ersatzteile und ein Verschlussstück für den Druckschlauch liegen bei.
    Deutlich effektiver als eine Hand-Pumpe..
    Langzeit- und Haltbarkeitstest stehen noch aus.
    Alles in Allem ein sehr gutes, wertiges Gerät.

    Great compressor!
    This compressor works well and is quiet compared to other ones. Great weight and size to move around to different places. I like that it can be plugged into either an outlet or my car. It came very nicely packaged/padded, and also came with tools.

    Filled up high pressure tank with no issue
    I bought this one to fill up high pressure tank which is almost 3050 PSi. It works quietly and tried both power outlet and battery connection. I can also easily carry, it is not heavy. I initially tried couple of other compressor, but none of them was that much powerful. Only thing, it is kind of expensive but the performance is satisfying.

    SUPER Heavy duty! Wow immediately after just pickup up the box you’ll know the quality of this bad boy. Super compact yet very heavy. Works great, very efficient and even fairly quiet.

  31. MM (verified owner)

    This filled my 1L scuba tank to 3000psi in 28 minutes.
    This is important because every 30 minutes of run time, this has to shut down for cooling.
    Surprisingly the noise from the cooling fan is louder than the pump itself. This is loud, by the way, comparable to a large garage air compressor.

    It works good no problem with contaminants or smell.

  32. Christopher Stockton (verified owner)

    This has been a great asset to my paint ball team. We no longer have to pay the $10 to get the tanks aired up and only takes a few minutes. The quality of this machine is great.

  33. Nom Nom Nom (verified owner)

    Scuba tank refill. What a great way to refill my scuba tank and my paintball tank.
    This comes with all the necessary accessories to get you started. My favorite feature is the anti moisture mechanism to remove water from the air.

  34. TS (verified owner)

    Fantastic little compressor! This powerful little compressor arrived quickly.
    Easy to hook up. Works on 12 volt or 120v hook up so great for car or home.

  35. D Schmertz (verified owner)

    Not quiet, but works well, and is solidly made.
    I got this for paintball tanks, and it works great. Quick refill. It’s not quiet by any means, but it fills the tanks pretty quick, and if you use it outside, the sound isn’t too noticeable. I like that it has a 12 volt option, so I can run it off the car battery and don’t need to find a place to plug it in.

    The assembly quality is solid, I expect this to last a long time given how heavy it is, and the obvious attention to part quality.

    This unit is great for high pressure tank refills.

  36. C (verified owner)

    I was tired of paying to get my tanks filled to use my gigantic air rifles. Well, this does the job and I don’t even have to leave my garage. Even my 72 cal monstrosity works just fine with what this can do.

    It’s not that loud. I expected it to be louder than my normal air compressors, but it really isn’t. It isn’t exactly silent, but it’s nowhere near as loud as I was expecting. It works on plain old 110v and I have yet to have a single problem with it.

  37. R. Logue (verified owner)

    This device blew me away.
    Comes with all the adapters so didn’t need any to fill my PCP air rifle.
    Took about 5 mins to fill. Used it in 12v in the field, and at home 110v.
    Easy instructions, breeze to use. My friend has a 1 ltr scuba tank and fills it in no time.
    This is a life saver for compressed air! Pros, easy to use anywhere, fast cons, none, Price well worth it

  38. Xephz82 (verified owner)

    Very compact, strong compressor, relatively quiet, fairly easy to use.
    This is definitely a compact and useful pump to have for light scuba tanks and airsoft shooting.
    It works great for many of the scuba tanks I use for basic diving. One thing I will say is that this is not something I would use for those big scuba tanks. I am unsure if it has the power to pump those big tanks.

  39. Christine K. Cornett-McVay (verified owner)

    Very user friendly, Works fabulous and I love the compact size for easy carry.
    A must have emergency item for long trips in my opinion. Easy to figure out how to use and inflated efficiently and with good power. Not super noisy and really durable. Great quality for the price in my opinion.
    A great gift idea for someone who travels a lot.

  40. Scott L (verified owner)

    Effective and portable.
    Grabbed this as a portable compressor for air rifles and as a middle of the road unit for use instead of the larger compressor in my garage.

    Worked great for a weekend bachelors camping trip filling up air rifles and paintball canisters off of my buddies truck battery.

    Manual is actually readable unlike some auto translated manuals. All the fittings look well made. A small negative note is the carbon filters being stored in the same bag as other parts and rubbing off dust.

    Everything worked great out of the box and was quieter than I expected. That’s not to say it isn’t noisy, but I was expecting it to be much louder. The cooling fans are definitely beefy though it’s probably best to follow the manufacturer’s guide of letting it rest after some use to extend its lifespan.

    Overall I’m pretty happy with this. The pressures all read correct when double checked against my larger compressor.
