Impressive PCP Air Compressor for the Price!
I recently picked up the GX PUMP PCP Air Compressor CS1-I, and I’m really impressed with its performance. First off, the built-in power adapter is super convenient, and the auto-stop feature is a game changer—it shuts off automatically once the desired pressure is reached, which makes things so much easier. The compressor is oil and water-free, which means less hassle and maintenance, and it runs quietly compared to other models I’ve used. I’ve used it for my air rifle and scuba tank, and it handles both without issue, reaching pressures up to 4500 psi with no problem. It’s compact, easy to move around, and does the job quickly. Overall, it’s a great value for anyone needing a reliable, portable air compressor for their PCP guns or diving gear. Highly recommend it for anyone looking for an efficient and hassle-free compressor!

Dependable and as advertised
I have had my GX CS1-1 PCP air compressor for over a year now and have used it many, many times to fill my PCP air guns. I have never had any problems with it. It works as advertised (at least mine does). I probably should get some extra moisture filters though. One thing I recommend is to disconnect the air hose and hang it up so that it can dry out between uses. Keep the compressor clean because it does build up heat.

Broke after a few times unable to contact company
This compressor was great. Had it for 6 months and used it a few times(about 4). It wasn't fast but it was very portable and could run on dual power sources without having to carry around a converter. It did however break and is unable to get above 3000 psi. I have tried to contact the seller since it is still within the 1 year period. I have exhausted all patience and effort in the hopes this compressor can be fixed. All in all this was a great compressor in terms of price, performance, and portability for all the 4 times i used it. Just know that this compressor will not last.

Great price, great performance.
Received it today, unboxed and used it within minutes. Worked great, 5-10 per tank fill, not as noisy as I expected, auto psi shut off worked great. Unit is nice and compact, super easy to use, would definitely recommend for anyone looking for an inexpensive, powerful and easy to use unit. I am useing for filling my .05 Liter scuba tanks.

Failed on its 2nd use but customer service is awesome!
Loved this pump when I used it for the first time. Filled both my pcp guns with no issue at all! Fast forward 4 months later to use for a second time and it won’t build pressure at all past 1000 psi. I’m past the return/replacement window so I’m pretty pissed that I’m left with a $300 paper weight. I would avoid this pump and look elsewhere *UPDATE* Contacted the company after this compressor failed & I do have to say they have amazing customer service! They helped me with the issues I was having & took care of the problem. Hoping this one lasts because it is a great compressor. Thanks again!

Great Compressor!
Nice compressor from GX. This compressor pumps fast and I have had zero issues with it. GX has proven itself to be one of the best if not the best compressor company in each of its compressors price ranges. They also have the best warranty of 1yr where other companies typically only offering 90 days. In the bag comes everything you need from the 12v cables, fill hose, block off insert, AC cord, extra filters and blowout discs. This compressors needs no oil or water to keep it cool due to the high speed cooling fans that work very well. Everything is built right in to the GX CS1 including the pressure gauge with automatic shutoff, temperature gauge, 220 or 110 volt switch, 12v or AC switch and the built in power transformer. It also is fairly light weight at only 17.5lbs. When filling my Umarex Origin from 2,000 PSI to 3,200psi it only took roughly two minutes which is a whole lot better than hand pumping every time I need to refill. So if you are looking for your first PCP compressor or replacing one, look no farther than the GX CS1.

Me llegó a Argentina de diez todo. Aún no lo probé pero es un muy buen producto y a precio acorde. Demoró un poco más de lo esperado pero todo bien por ahora. Excelente lo de 110-220V para que funcione en todos los países.

Great PCP Air Rifle Compressor
Great compressor for airing up my PCP air rifles. My Air Venturi Nomad 2 compressor finally gave up the ghost, so I went looking for another high pressure (4500 psi) compressor. that wasn't as expensive as a Nomad 2. I read lots of good things about this PUMP (a GX CS1-I) and decided to give it a try. I placed the order on 5/16/23 and it arrived on 5/19/23, as promised. Today, I used it to top off my Daystate Wolverine HP .25 caliber air rifle from about 160 bar to 250 bar - and it went great, I didn't time it, but it didn't take long. It was easy - all I did was (1) plug it in, (2) open the bleed valve, (3) hit "AC" lever, (4) pressed start and (5) closed the bleed valve. That was it. I had already set the auto cutoff to just under 250 bar and watched as the rifle aired up. It cut off just right. I'm happy so far.

J'ai fait entre 30 et 40 remplissages pour mes réservoirs airsoft (48ci et 68ci). Le compresseur a ensuite cessé de fonctionner. J'ai essayé d'obtenir des pièces de rechanges chez le fabricant, mais pas eu de réponse. Donc si je calcule que je peux faire remplir mes réservoirs dans les centre d'airsoft pour 5$ le remplissage, l'investissement ne vaut pas la peine. 40 remplissages à 5$ = 200$. Je m'attendrai que le compresseur dure au minimum une centaine de remplissages.
