GX PUMP CS2 Portable PCP Air Compressor,4500Psi/30Mpa,Fast-Fill

Nice air compressor—not too loud but not silent either. It fills my Gamo PCP from nearly 0 to 200 bar in less than 8 minutes. Pros: Good price. Cons: Poor instructions, but great after-sales support. I usually email them, and they respond by the next day. I recommend it! P.S. When doing your first test, keep a close eye on your gauge—within 10 seconds, it can hit 3000 PSI. I blew the main seal the first time, but the built-in safety worked as intended. The burn disc is easy to replace, and spare parts are included in the package.

The few times I’ve used it, it’s been excellent. There is one drawback for me but may not cause others a problem is that most PCP air rifles quote bar for fill pressure, the gauge is very small and is in PSI so I have put stickers on side of machine with the converted pressures. Also there isn’t a temp gauge so if you have access to a laser temp gauge is useful to have to hand. None of these observations are causing me a problem.

Great compressor I don’t like the fixed wires I like cordless so I modded mine I replaced the wires to a Socket and fitted a buck converter and now it runs of a dewalt battery and mains and car battery And no wires

I have only had this compressor for a few weeks now and I am very pleased with it. It practically is all setup ready to go out of the box. You simply need to connect the handle. The transformer plugs into a 240v 3 pin socket and you connect the clips from the compressor to the transformer. You just screw the air release valve to close it and switch on. Keep an eye on the pressure gauge but I’ve find it pretty much fills my Gamo GX-40 within a couple of mins. I find it fairly quiet as compressors go, checkout video. It is very portable and easy to carry, fairly lightweight. Comes with spare parts. Would have given 5 stars except the manual that comes with is not for the model. Had to question a couple of things with the supplier who did respond to one of my questions. Having been using a hand pump, this little gem is allowing me to shoot more in quicker time.

Really good piece of kit, well made not noisy.

This has proven to be an excellent pump so far. I use it to pressurise my Kral NP02 PCP. It takes around 3 to 5mins to refill the cylinder. It’s not the cheapest pump on Amazon & it’s not the most expensive but it does appear to be very, very good quality for the money. It requires very, very minimal maintenance. Which was a big thing for me as I didn’t want to be messing with frequent oil changes or with the water cooled system. This is simple plug n play & apply some grease every 50hrs of use.

Dont bother for a pcp air rifle pumps loads of water threw the compressor and damaged my reg on the pcp and after using it for a month has to take my pcp to someone who cleans barrels as there was rust ..save your money honestly takes 20 minutes to fill the pcp ...crap

a nice compact airgun pump unit, tops up my tank in about 3-4mins, time will tell just how well it will work in a year or two, but saying that I'm very pleased up to now. I should have added the extended warranty.

I have been researching this pump for a while. And pretty much everything I have read is true, compact, well-made, with extra filters and burst disks. As I only got it today (07/09/25), I cannot comment on reliability, but I will update this feedback after a while has passed. The fan is not quiet, but acceptable, same for the pump, the icing on the cake was the delivery was early and the packaging was in good condition

I lived on a Shoebox compressor for ten years and it finally gave up the ghost. I don’t fill SCBA tanks, just straight to the gun cylinder. If you are filling directly to the gun, the product is perfect. So far the quality control and engineering seems very good. This unit has delivered as advertised and has worked perfectly. I have read the quality of grease in the gear drive is not good but that was 3 year old reviews. I only hope they have gone to something better by now? The GX folks need to re-write the manual because you can basically throw it away, but other than that nitpick I can recommend this product.

Fijne compressor. Ik had eerst een compressor van vevor. Deze was binnen 6 maanden kapot. Deze ziet er kwalitatief veel beter uit. Hier heb ik veel meer vertrouwen in! We gaan het zien!

Es pequeño pero de muy buena calidad hice su prueba de llenado y es rápido no tiene apagado automático pero yo nunca dejo mi rifle llenando sin estar al pendiente es muy facil de utilizar

Ich kann diesen Kompressor allen empfehlen, die sich noch mit einer Handpumpe abquälen. Er wurde schnell geliefert und war bestens verpackt. Und endlich eine Bedienungsanleitung in festem Einband und mit grosser Schrift. Ersatzteile und Werkzeug lagen ebenfalls bei, dazu ein zusätzlicher Filter. Die Verarbeitung ist sehr ordentlich und hat meine Erwartungen übertroffen. Die Inbetriebnahme war - auch dank der Anleitung - überhaupt kein Problem und mein Weihrauch HW100 in kurzer Zeit von 0 Bar auf 200 Bar aufgepumpt. Das Gerät schien sich dafür nicht sonderlich anzustrengen. Von mir eine klare Empfehlung...
