PCP Air Compressor 4500Psi/30Mpa Water/Oil Free PCP Air Pump Rifle/Pistol Paintball Cans Powered 12V Automotive DC 110V AC For Home Use With Power Converter And Oil-moisture Filter Easy Carry

Compared to a manual pump, this electric pump is like comparing a horse to a Porsche. There really is no comparison.It fills PCP tanks in a few minutes and seems well built. If you are tired of using a manual pump (I was sick of that option within ten minutes of owning one) this a solid choice in entry level electric high pressure pumps. Longevity? I am still uncertain, but it doesn’t feel or look like junk. It seems sturdy and even the packing and securing of the pump in the delivery box is first rate. Negatives?Yes it’s loud. Yes, the temperature gauge reads only in Celsius. Yes, the directions are written in comical Chinglish. But you can easily figure everything out from the full color pictures in the manual, and best if all, the pump just plain works. I used it to charge my Notos PCP from 0bar and it was very fast. I consider this a solid buy.

Overall works really well. Does the job, can't complain.

Worked great for exactly 33 days, used probably 8 times in that month then it just won't compress air seems like. It's running but not creating pressure to fill tank. Thought I'd get at least 6 months out of it, trying to return it now, see what the manufacturer does (hopefully honor 1 yr warranty)

I've only tested the "NUOGE PCP Air Compressor 4500Psi/30Mpa" a couple of times, so this is just initial impressions. I'll revise this if more experience warrants it.First: "4500Psi/30Mpa" - Nope. This equivalence only works if one assumes that 1 MPa (not Mpa) equals 150 psi, but it does not. 1 MPa equals almost exactly 145 psi. (Maybe everyone in the PCP airgun community assumes 150 psi by convention, but I doubt it.) The compressor's gauge, documentation, usage limits, over-pressure blow-out disk, etc., are all rated in MPa. Thus, taking their gauge and limits at face value, the compressor tops out at 30 MPa = 4,350 psi. Try to get to 4,500 psi and you're a hair over 31 MPa, which is into the "red zone" of the compressor, approaching the blow-out disk limit of under 33 MPa.Moreover, the gauge and documentation has two levels of allowed operation: up to 20 MPa (the 'Green Zone"), and 20-30 MPa, the "Yellow Zone", which is allowed, but requires particular caution regarding overheating or over-long run time, as well as the possibility of shortening the compressor's useful life.So, to be conservative, this is a 20 MPa compressor (2,900 psi). A good many PCP airguns run at 3,000 psi, or even less, which is 20.7 MPa, barely into the Yellow Zone, so should be fine. If you have a 3,000 psi airgun, you are fine.Confession: I don't even have an airgun yet, but am looking at two models, one rated for a 3,000 psi fill, the other for a 3,500 psi fill. The first will be comfortable. The second, at 24.1 MPa, is a little under half way through the Yellow Zone. As far as I'm concerned, this a a 3,500 psi compressor too, but "pushing it" a little bit. Taking their ratings at face value, I'd not buy this for a 4,000 psi routine fill (27.6 psi), expecting that regular use at that level might shorten its life.Update: Reviewing the manual I noticed: "It is recommended to maintain the normal 25 mpa pressure to maximize the life of the machine." This, coupled with other written cautions, suggests that the routine pressure limit of this compressor should be regarded as 25 MPa (3,625 psi).Without an airgun (or tank) to fill, I did a couple of tests pressurizing the air line and filter body. The results were puzzling, perhaps indicating a small air leak somewhere, which I've not made a serious effort to track down. A light oiling of the male foster fittings (with silicone airgun chamber oil) may have helped slightly. Regardless, I report my experience, hoping that someone with more experience will comment to give another perspective. This is for MY compressor, and MY accessories, for better or worse.Others reported not receiving a foster male "plug", allowing an easy pressure test. My compressor came with a nice stainless steel one (also a generous collection of O-rings and filters). I plugged the outlet of the filter body with it (and for another test, used a similar plug that I'd purchased separately).It took over 5 minutes to reach around 3,000 psi, and over 8 minutes to reach just above 26 MPa (about 3.800 psi) - obviously starting at atmospheric pressure. I live at about 2500 feet altitude, in a very dry climate, with an indoor temperature of about 73 degrees F (about 23 degrees C).The displayed temperature (degrees C) never exceeded 45 degrees, well below the 70 degree C operating limit.The power supply got fairly warm, especially on one side. It was laying on a table with the fan opening up, but that partially blocks the air inlet openings on the bottom. I peeled off the plastic covering of the aluminum case at the bottom corners and glued on 4 feet, raising it up for better air flow - that seemed to help a little with it running perhaps not quite so warm. It cooled down quickly when the pump was turned off and only the compressor fan was running for compressor cool-down.I'd leave the fan on for quite a while after turning off the compressor, as the temperature starts going back up when the fan is turned off, even after the compressor has been off for a couple of minutes, as heat continues to flow out of the inner parts of the compressor. Definitely don't turn off the fan immediately after the compressor. Your observation of the temperature will show you what works for your usage cycle.Once the compressor was turned off, the indicated pressure dropped quickly (over some seconds) but then stopped at exactly 20 MPa (the top of the "Green Zone"). From there, it began, very slowly, to decease, over a period of many minutes. This first, rather rapid pressure drop, suggests an internal release of some kind when the pressure is in the Yellow Zone, but that is mere speculation. The further very slow decline suggests a slow leak somewhere in the system, internally or externally. Whether that is internal (and perhaps "normal") or external, is yet to be determined.So there you go: the pump seems competent up to perhaps 3500 psi, but not much beyond, and my unit may have a small leak somewhere, possibly around the opening of the filter casing, etc.If I resolve the potential leak, or find it to be internal and troublesome, or have other issues, I'll report back. Meanwhile, it seems a likely buy for the money, and I'll be keeping it for the upcoming purchase of my first PCP airgun. You can judge for yourself what to make of my initial experience.

This compressor is noticeably slower than my larger compressor but it is much easier to use. Small and portable and can work on 12vdc or household 110vac. I use mine at my home shooting station and use it to refill my airguns and my small "buddy bottle." It is handy and works well. No maintenance (no oil changing or water cooling). For me. the only downside is that it is noisy. Would I buy another? Yep. I've only used it about 20 times over a two month period, so I can't speak to long term reliability

Pumps up my Benjamin Marauder .25 from 1,900 psi to 3,000 psi in about 2 minutes. Yes it's loud but not much louder than a vacuum cleaner, not unbearably loud. I've used the pump over a dozen times without issue. Spare O-rings and filters are included, thanks. I'm happy with the purchase.

This compressor can’t seem to maintain consistent power. It starts out fine, but thenit drops off and loses pressure halfway through the fill. I’ve had to restart it multiple times just toget a decent charge, which is frustrating and time-consuming.

Filled my mini reserve tanks with ease.I like it works on both 12 and 120v
