PCP Air Compressor CS1-I with Built-in Power Apdater,Auto Stop,Oil & Water-Free,4500Psi/30Mpa,Powered by 110V /220V AC or 12V DC,PCP Compressor Pump for Air Gun and Paintball/Scuba Tank

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!

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.

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.

Just received this compressor.I filled my Beeman "Raider" .25 rifle from zero psi to 3000 psi in 3.5 min.The auto shut off worked perfectly.The room temp was about 70 degrees.The pump temp rose to about 42 degrees, well within the safe zone.Under most normal usage, I would not empty the guns tank to completely zero.Will update this review if need be, after more use.

Fills my gun well takes about 12 minutes to fill to 3000 psi, center row of lights on led temperature display already not working but pump still functional after 1 month.UPDATE: Five days after the 30 days pump had some kind of electrical failure and would not turn on... Contacted seller he replaced it free of charge within a week. AWESOME COSTUMER SERVICE!!!

This product works as advertised. I was impressed by how well packaged the machine was. While the machine is loud, I have heard others that were much louder and more expensive with the fill time being being the pretty much the same (based on actual experience on using different machines, but never actually timed tested).If you are using a pump for filling your PCP gun, then you are using a lot of energy and time just to fill up you tank.I love that I can just press the start button and walk away (or reload my magines) for a few mins to a completely filled 250 bar (from around 150 bar) once the machine automatically stops.This machine allows me to focus on the things that matter rather than doing what feels like a thousand pumps.

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.

Worked well for a few months and then would not put out more tha 300 psi to a small air tank.I purchased this on February 1, 2024 and contacted them with this problem on November 14, 2024 while the item was still within its warranty.I received no response even though I asked for warranty replacement specifically and the problem continues. Today, March 14, 2025.I emailed them again attaching a copy of my November 14, 2024 email requesting resolution to the problem. At this point, I want a refund. I don't wanna buy a troublesome compressor again, and even on Amazon, it says "frequently returned product"
