GX PUMP GX-E-CS2 Portable PCP Air Compressor, 4500Psi/30Mpa, Oil-Free,Powered by Car 12V DC or Home 110V AC with Converter (Included), Paintball Tank Compressor with Extra Moisture-Oil Separator

If you can plug an electrical plug into an outlet, distinguish red from black, "+" from "-", and turn a switch from off to on....you too can setup, operate, and enjoy this machine.Is it slow? Not for what it does. I only run mine for 15 to 20 minutes at a session. Then I let it cool down for an hour or so.Does it work? YES!!!No water pump, no water hoses, and it is QUIET!!! I ran mine in the kitchen with the 110 voltage converter. You can also run it off your car/boat battery. (Suggest you let the car motor run to avoid running the battery down.)Oil??? No! Grease in an applicator, and two threaded plugs that you unscrew to put a bit of heavy grease on moving parts when the time comes. The compressor comes pre-greased!!! So plug and play upon receipt.Max pressure is 300 BAR/4500 psi. May I suggest you go no further than 4000 psi. Experience has shown fills above this pressure just do not return enough extra shots to be worth the effort.My other Chinese compressor, water cooled is long gone. This one is too simple, too effective, too inexpensive, too reliable to save a $100 USD and later struggle with the cheaper brands.It appears to have a larger second stage piston, so it can pump slower, run much cooler, built-in fans supply air flow...you need one of these. Yeah...it's Chinese made, but a much superior design from the water cooled units.I'm 76,and did ten back-flips after filling my pcp, and a .5L pony bottle. The ambulance driver said to just use the pump next time, and rejoice quietly!!!

I wanted to give it some time before I gave this a review. Honestly being so inexpensive had me kinda worried, since people swear you have to spend almost a grand on a decent compressor. I bought mine in November, so over 6 months of filling my Marauder tank with ZERO problems! Ok wait, maybe not zero, I did switch out the connector/gauge. Only because it was not the easiest to hook up to Marauder which doesn't have a removable tank. So that's both the pumps fault. The Marauder doesn't have a big tank, but it's crazy how fast this thing tops it off from 2k to 3k psi. I need to time it, but I know it's not more than 6 or 7 minutes. I've never had to shut it down mid fill to let it cool because it never takes that long. They say you can run it 15-20 minutes with no problem, and I believe it, but I wouldn't do more than 10 since that's what kills these things. If mine died tomorrow, yes it would be under warranty, but even if it wasn't I would still get another 1 of these. You spend a grand, it can still break, but you can buy 4 of these for the price of most big name compressors. I promise you you won't get more production from 1 big name compressor than 4 of these. It doesn't make sense to spend all that money unless you are 1 of those guys who enjoys throwing money away. Personally I would rather put it towards my next gun. Don't be scared off by the price, this thing is worth every penny. Most bad reviews on here are from people who aren't very realistic. Performance for the dollar is off the charts!Ok, I have had this thing a year and a half now and it still works amazing. My PCP is a Benjamin M-rod, so it doesn't have a very high bar tank. It fills at 3k. This compressor is PERFECT for that size or maybe a little bigger. I let my buddy borrow it for his FX, and it's tank is 4k. It honestly struggled a bit with that size. It filled it, but it really had to work. He was still impressed and went out and bought a bigger size from a different manufacturer and almost immediately it fried the compressor. He returned it and bought the bigger GX comp and he loves it.GX without a doubt is the best deal on compressors on Amazon.

I waited a couple of months to post. It has been working flawlessly. I have a little 8" fan I point right on it from inches away whenever I use it kicking up the cool airflow. Heat is what kills these things. As long as you use it within spec and avoid "tank filling" like the plauge it will last. This is compact, quiet and I could go on and on about things I like. The gauge is OK at best which I expected. Luckily these compressors are just hardware fittings so you can add whatever you like in the way of air filters, gauges, hoses etc. Just keep in mind this is a small airflow compressor so things like that will slow your fill and cause more heat.It is a great design but I have one constructive critisism. With the move from shrouds to moderators and shorter barrels many guns out there have a tight fit between the end of the air tube and beginning of the moderator. This unit ends with a big square metal block that is not flexable at all. To use this compressor on those guns you have to buy a flexible micro hose. Problem is you only need 6 inches but you are lucky to find a piece of hose with fittings 24". The block also has enough weight and sharp corners to scratch blueing or wood on the gun. A small bit of hose would keep it back from the metal/wood and allow a flex tight fit between the tube and moderators.THIS SELLER IS ONE OF THE BEST ON AMAZON and I buy a lot of stuff. I asked him several technical questions before and after purchasing and he always gave quick and accurate responses. I really like my purchase and have recommended this to friends and people on Airgun sites. This beats the heck out of a high quality hand pump for not much more money.
