CS2 Portable PCP Air Compressor, 4500Psi/30Mpa, Oil-Free,Powered by Car 12V DC or Home 110V AC with Adapter (Included), Paintball Tank Compressor with Extra Moisture-Oil Separator

I have a Benjamin marauder 25 and an air Venturi avenger 25. So far it is a solid pump have used it for a while now just filling those two rifles. The air reservoirs on the rifles are around 215cc and on from 3000-4300psi on the avenger it takes roughly 2 min to fill and on the marauder 2000-3000psi just under 2 min. Instructions are very minimal, but not much to the pump either. There is a schematic in the manual which will more than likely come in handy when orings need to be replaced. This is my first pcp compressor and if you are looking to just fill you rifles I wouldn’t hesitate. I don’t have any large tanks to test this unit out on, but it says it can run 20min continuously before needing to shut pump off and let the fans cool it off. A little cumbersome with the inverter for wall power but definitely manageable. As for just running off a 12v battery I have not tried that.

Updated: Finally my AEA compressor arrived so put the 2 to the test. For obvious reason the AEA is much better than this little guy because of the programming and the New AEA goes all the way up to 7000psi. This comp is only 80-83 db compared to the AEA which is bumping the 90 db.The burst disk blasted recently and I thought its something inside int he compressor, it was easy fix once I figured out what it is. I think this is the newer motor version what I got, not to loud, charged the BW T9 from lil over 2 min. same tank with the AEA is under 2 min. I do not have very large tank but the Mad dog 48ci is lil over 20 min compared to AEA is 17 min. Over all well worth the money. So I changed the 4 stars to 5 stars

After over a year of use I am very pleased with this small compressor. I use it to fill up to 500cc tanks and it works great. Quality construction and materials. Zero problems or complaints.

I am new to PCP's and of course having no prior experience I did not know which compressor to buy. After much research and looking at the reviews I decided to order this one. For the money I think these could come with a small book with information specific to using it but there are youtube video's to watch that help. After buying this I filled my new gauntlet from zero to 4500 in just a short runtime. I also acquired a scba tank kind of by mistake on ebay but with a current inspection and not expired tank date so I decided to fill it to 4000 psi with this little compressor from zero. It is winter time and I had plenty of time to just fill it a little at a time. I decided that I would only run the compressor for 5 to 8 minutes at a time so not to work it too long. I still had a return window and thought what the heck lets check it out to see if it will work or I will send it back. Well, I also changed the filter out to a larger one to keep water out and around 22 sessions of the 5 to 8 minute later my tank is at 4000 psi. This little puppy reminds me of the little engine that could and while it is slow to fill a large tank, it can, if you treat it right. It just kept chugging along. I still have a return window left but for this little puppy's portability and it's ability, if it continues to work as well as it has I am sure I will be keeping it. I will update this review if I have a problem in the future. I hope the seller is as reputable as many have stated should I have a problem. There are risk to buying these types of items at these prices especially when parts are hard to find but compared to other more expensive compressors you will be hard pressed to find one with this many good reviews. I hope this helps some of you on the fence about ordering this little unit. Good Luck.Update :After running this little gem for close to 3 hours or so total and right after filling the tank mentioned above, I decided that I wanted to check the Piston lube just to see how it was looking. I pulled the plastic plug that covers the piston connecting rod and right away I noticed that the piston had been wearing the end of this plug, in fact it had worn a curved wear mark in the end of this plug curved like the piston. Obviously it had been tightened to far into the cavity, the plug was worn to the point that you could see through the center hole. I thought well, I had better pull the piston to see how much plastic was down inside the cylinder. i pulled the piston and found the piston looked ok but there was very little grease on the piston and what was there was too dry but the cylinder wall looked fine. I noticed that there was indeed black plastic wear that had fallen down beside the high compression piston and there was black stuff up and down the high compression piston but the piston and rings had not been damaged at this point. After watching YouTube videos of a broken compressor and the dried out grease that probably contributed to the drive gear wearing out in that video, I decided to take this one down and evaluate the grease inside the gearing as well as the rod bearing. I found that there was plenty of grease in these areas but I didn't trust the grease that had been used so I removed the old grease and used a high quality grease on the gears and the rod bearing and connecting rod. I chose red atom grease for these areas and I lubed the piston with white Lucas lithium grease both purchased from amazon. Both of these have high ratings and are not warranty breakers as you can see in the questions and answers section that the seller is ask about what kind of grease to use.I put the unit back together after cleaning and greasing the unit and ran a pressure test which proved that the grease I used was definitely superior to what it had before as the unit ran a little faster and quieter than before and pressured up just fine. That test was without the plastic plug installed because I had filed the end of the plug down shorter and applied epoxy inside to seal it as it had not dried yet.The next day I had to depressurize my Gauntlet air rifle .13 cu tank to perform some work on it and after that I installed the plug in this compressor that had dried plus I installed an oring on it to insure that it would seal properly and not thread in too far, any oring the size of the plug should work as this area does not get too hot and this plug only needs to be snug to stay in place. I then aired up my gauntlet tank to 4500 psi and it took approximately 8 minutes from zero to 4500 with my newly greased compressor.It is still the little engine that could but I am reducing the rating to 4 stars overall because I feel that if I had not found this problem I probably would have had serious problems with it real soon. This should not happen to a well thought out piece of equipment with properly made parts and good QC inspections.I hope I can continue to use this little unit and it is my belief that anyone with one of these units should go through it as I did and probably should make this a regular maintenance check. That is what I will be doing and I will update if I find any other problems. Again, this is a nice little workhorse but it probably needs some good old corrective inspection and maintenance for proper long term use. Hope this helps.Update: September 27, 2023.This little compressor is still working great. I continue to use it regularly to fill my scba tank when it gets down in the 3600 psi range back to 4000, which are good ranges for filling my Umarex Gauntlet and my Umarex Origin 22. It takes only 2 to 3 eight to ten minute sessions to top off the tank and then I am good for several fills. I have to say that this little unit has proved to be worth the money, if taken care of. I will probably take it back down this winter and check it out and grease it where needed.Update: 02/13/2024I just checked cleaned and greased my unit and the cylinders where nice and smooth. Good grease that I mentioned that I use above. I reassembled the unit and discovered that I was getting no pressure. What did I do wrong, Took me awhile to figure it out but just in case some of you have an issue I will tell you what I did wrong. If you take the intake check valve apart on the head to clean it pay special attention when you place it back together. The top piece of the check valve has a slight bend near the screw so that the inner piece of the check valve can move slightly up and down to allow air to come into the head. If you place this on upside down the valve will not open and the high pressure piston will starve for air causing it to be operating in a vacuum. Trust me, you will not get any pressure if you do this. I fixed my error and presto, pressure. I still think this is a great little compressor if you take care of it. I expect to use it for another year without any issues.

Brand new and fast delivery. Great little pcp compressor

I followed the included instructions, NEVER ran more than MAX 14min, so i KNEW i was treating easy. How did I keep less than 15 minute run time? a 20A Commercial Light Timer. The draw was low enough to where i could even use a 15A digital garden-nursery timer and set for 14min precisely.Here is what happened: I ended up somehow running the AutoShutOff ORION Compressor(like YongHeng) for about 6 months. It would fill my 68ci bottle super fast, but wife ABHORRED the LOUD noise and vibrations. I NEVER let ORION Compressor 4500psi get over 54celcius. For this, I used a thermal Switch for Duct/Heating management. I put modified temperature probe into the fins-area of YongHeng clone and when it reached 54C, it would auto-shutoff in event of me walking off and sidetracking. So, TWO failSafes in place. Yet I ended up having a dead ORION Compressor. I got about seven months out of it. It fills possibly exponentially FASTER than this model. THe Orion/YH clone, I always ran with a 20gal water reservoir, and a $200.00 inline filter with desiccant inline. THe issue with the WaterOil external separator anf the Orion/YongHeng- CANNOT air tanks beyond 4350psi NOT 4500 due to the volume needed to fill H2O/Oil separator.I wanted to be able to run Truck with 3000watt Modified Sine Wave inverter/Isolator/AUX battery system to run this remotely in woods, but when it died, i saw the 12volt GX portable compressor and THOUGHT i had a solution.'This FIRST GX Portable 4500 arrived. The gauge on the output line of GX NEVER did work. within two days, i had a replacement. it lasted about 24 days. Unfortunately, I did NOT use over the weekend as i was skiing. That ENDED return window. I went to Air-up yesterday, FOUR DAYS after Amazon Return window. and OUCH, ANOTHER DEAD AIR COMPRESSOR. Runs and SOUNDS like it is pumping, yet it wouldn't even pump a 68ci 4500 from 3600-3700 after 14min. Also, the Alexa/AMazon Smart Plug WILL work to run this GX Portable. You can easily yell at ALaexa to SHUT off or do manually over AlaexaApp. This is, yes, ANOTHER FAIL SAFE….ANOTHER US$400.00 DOOR STOP - NO OUTPUT. NOTHING TO EXPLAIN WHERE TO TROUBLESHOOT!!!???I have only purchased two Asurion insurance plans. DO NOT EXPECT an actual '3 year / 4 year Warranty’ sold by Asurion to BE FOR THREE OR FOUR YEARS OF COVERAGE. IT IS A ONE TIME COST RECOVERY expense. THe Asurion rep told me, ‘Well how lucky for you that you CHOSE to buy the Warranty, just imagine IF you had not! You would have lost ALL $400.00!, So, be GLAD you bought it and it will replace at least ONE TIME.’ THat was the response to me saying ‘False Advertising is suggesting a Three or Four Year Protection plan, but it only works ONE TIME, four days after 30-day Return window?’ They were reasonable to work with as an Amazon CS agent was also on the line monitoring.Normally, i would say USER ERROR. GX Portable 4500 is is NOT my first Compressor Rodeo; nor will it be my last. PCP rifling is addictive, especially when you have a 300yard range out back door with 50+ targets all ranged out.I currently use five PCP rifles and pistols MOST days a week, with average 4000-5000 rounds a month fired. So, inevitably, WHEN I FIND A COMPRESSOR that does NOT become another HEAVY DOOR STOP being a short-term EXPENSE..... i will be sure to write all about it too.
