PCP Air Compressor, Portable 4500 PSI/300 Bar Air Pump, supports 12V DC or 120V/220V AC, Auto-stop, oil-free/water-free design, for Paintball, Air Rifle, HPA Tanks

Arrived quick and packed very well. I have used it once and it worked famously! Many thanks!

Very nice cooling fans some of the beat I have seen in this field fills 13 ci tanks in like 7 minutes

EDIT: I am reducing my rating because after a year of fairly light use, it is scrap metal so far as I can tell. It started taking longer and longer to pump and finally could not make pressure, so I opened it to do maintenance. These pumps use dry seals and no separate lubricant which is good but you need to be able to replace them when worn. The orings they ship have nothing to do with this product, and they have no seal kits available so far as I can tell. I thoroughly cleaned all the parts and reassembled it. Still no change air leaked out as soon as I shut it off and not leaks were found. I flipped the disk on the high-pressure seal and got it to start pumping correctly and not leaking air at shut off. Now it cannot reach 100 bar. Since the valve is not leaking it means the seals are worn out. There appear to be no parts available, so a few months after their warranty it may be scrap metal. Will keep looking for parts from the other brands that sell the same parts, but I don't expect much. END EDIT This is a good, well-built compressor. The electronics, the motor, the pump body and the housing are all well done. I am used to an old, water-cooled compressor that failed, so it seems painfully slow at times, but compressing air to 300 times normal makes the air really hot and fans are not as good as water at keeping parts below the melting temperature of plastic seals. I think the portability provided by not having liquid cooling and having a 12V supply is a good tradeoff for most people, especially if they shoot in places without 110 plugs. I have been using mine for a little over a year, and the vent seal has recently been degrading and finally unacceptable, which prompted a tear down. The ball used to seal it is quite ugly, but it is a hard plastic and not metal so it will be black. This seems like a good choice to run on a plastic disc seal. My ding of one star is because of the details of the sealing bore. The same disc seal is used multiple places and there are 5 replacements shipped with the pump, along with Orings and filters and anti-explosion discs for over-pressure protection. The problem is that the edges of the seal start to deform over time, and this seal will need to be replaced fairly often. The proper way to do design this is to have a clean counterbore at the bottom of the valve hole, the depth of the seal thickness. Since this is the drill-tap diameter that should be easy. On these, the threads are too deep. Under compression the disc deforms into the threads, and it becomes major surgery to remove it. I was only able to get it out by removing the block from the pump, drilling through most of the seal on a drill press, using a heat gun to soften the remaining seal and using an awl to pry the softened material out of the threads. A five-minute simple maintenance procedure was turned into an hour of major surgery because of the thread depth. It is too soon to tell if it would be easier if I had replaced the seal disc at the first hint of problems, but I won't be able to test that for a while. With the seal replaced, the compressor works good as new. This is a good compressor at a good price, and I would buy one again. I hope the manufacturer sees this and corrects the design details in the block, so future customers don't have to deal with this.

I bought the 18v Battery compressor. By the way this compressor is compatible with Makita 18V Battery BL1860B BL1850B BL1840B BL1830B BL1815B Batteries. The Manual say to use a 7.8 amp hour or bigger battery. I bought the Waitley 18V 9.0Ah for the compressor. https://www.amazon.com/dp/B07B4WFT86?ref=ppx_yo2ov_dt_b_fed_asin_title When I was unpacking the compressor and the 120vAC power supply I noticed something was rattling around inside the power supply. The 60mm cooling fan blades came apart in shipping. So I replaced the fan and all is good. Now The photos on this listing are not of the unit I received. The power switch is in the back, not the front. In fact the power switch is were the fuse is supposed to be. The fuse is no where on the out side of the unit. the car battery cables did not come with my compressor. The Compressor tested well. The compressor filled the hose to 4351.13 psi (300 Bar) in 23.49 seconds, using a 18v 9ah battery. I bought this compressor to fill my Benjamin bulldog M357. the m357 has a full fill at 3000 psi. On a Bulldog M357 after 5 shoots the pressure will drop from 3000psi to 2100psi. with this compressor using the Makita 9ah battery it can refill to 3000psi in 3 minutes and 20 seconds. The bulldog m357 has a 440CC tank (.44 liter) tank. After the refill the battery will drop to 19.9v from 20.4v. So with the 9ah battery you should get about 14 refills. The m357 has a 5 shot mag, so about 70 shoots with a full battery before you have to recharge the battery. If you hand pump the Bulldog it will take about 18 minuets. I will test it with the power supply at a later date. But it should be faster with the power supply. The auto stop work perfectly. The temp only went up 5c while refilling the bulldog. So it is a win with this compressor, even with the cheap power supply. If you are looking for a battery powered compressor and a good price I would say get this compressor. I will be updating this review after some field use. Update : Ok I took the bulldog M357 and the PCP compressor on a late season deer hunt. I was able to take down a 6 point buck with the bulldog and 2 Doe's as well. the PCP work well with my bulldog. and The compressor was faster fill the bulldog with a fill time of 2minutes and 36 seconds with the Power supply that came with the compressor. And yes I did replace the power supply cooling Fan. Very Happy with this compressor.

This works great for refilling my paintball gun bottles!

Works great. I have a pistol with a small air tank so it does not take long to fill. Pretty quiet compared to some compressors my friends have. I have only filled my pistol twice, so I do not know about longevity.

They wear out quickly even with maintenance.

Purchased this model compressor. Shipping was reasonable or better. I primarily got it to charge my PCP air guns . I hoped for a budget friendly unit it would satisfy me , somewhat of a perfectionist. For a 200$ unit I am quite happy after finely using it. It charged my 25 cal Beeman from zero to 3500 psi in only 4 mins. With my Diana Bandito which was half charged from delivery I had a full charge in like less than a minute It has 2cooling fans which are actually louder than the compressor. A hair dryer makes more noise. Air gun hobby on a budget, this is a sweet spot.
