  • 2. Compared with other cheap ones in the market, Our pump fills a 0.5 liter bottle, 0-30mpa is stable for about 18 minutes. But the competitor is 25 minutes for the first time, 30 minutes after several times, and over 40 minutes after 10-20 times using.

    Best in class by far

    A really great price and value for this pump. Worked flawless when opened and it shipped to my door in couple days.
    I plan on a SLA 12.8v or couple 4S LiPo to make ultra portable. I would never go back to a tank and get only partial fills.
    Replacement parts are inexpensive. Please GX! Keep making this pump available.
    Ps: GX responds fast to customer questions. I give them 5 star.


    Works great!


    A little workhorse. So far so good. Hope it holds up,seems to be of very good quality. Its longevity will tell us if it is truly a quality machine. Like i said so far so good. Would i buy again based on what i have seen so far. Absolutely!!!

    GXCS2..mostly great!!

    So far it is good. Only complaint is that it didn’t come with the spare piston ring it was supposed too. I do have an email to the manufacturer about that though.

    The little engine that could!

    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...
