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!

Fiabilité et mauvais retour sur investissement
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.

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.

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 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.
