Manual Stop Portable pcp air compressor 4500psi 300bar 12v DC or 110v AC with power supply,oil&water free,high pressure PCP Compressor Pump for Air Gun and Paintball/Scuba Tank

So far so good this thing has been filling my gun about once a day for a few weeks now and it works great. It has great power and fill speed it will fill a 300 bar air gun in less than 10 minutes. It's not too loud it sounds like a small vacuum cleaner indoors. It seems to be built well its very solid and well put together there is not loose parts or vibration sounds. The 12 volt dc gator clip and the AC invertor both power it well. So far it seems like a good unit it perfect for someone just getting into the hobby.

The PCP Air Compressor offers a good price and solid performance, though it's a bit slow and loud. To ensure it works well, follow these steps:1. Never start or stop the compressor under load—always use the bleed valve.2. Keep the temperature below 50°C. If it reaches 50°C before your airgun is filled, open the bleed valve and let it cool before turning it off.Follow these guidelines, and this compressor will serve you well. Ignore them, and you'll be shopping for a new one sooner than you'd like!

This had good reviews, watched YouTube vids showing still running great after a year so I bought it with a 4-year warranty. Received compressor on 9/16/2022, took out of the box, read the instructions, made all the connections as required then turned it on. It was VERY loud, ran for 15 seconds shaking the table it was sitting on, made a loud noise, thought it was going to explode then it died. Rechecked all the connections and turned it back on, unit runs, is quieter but produces zero air pressure and there is no movement on the air gauge. I got a bad one, so I'll be seeing how great Amazon's return policy is. Update: As I was packing this up to return, I heard parts and pieces of it rolling around inside of the case, in fact a few small chunks of metal fell through the vent slots. I'll be looking for a better built PCP compressor.

I really like this little guy.It's not made for filling large bottles, but if you use it with common sense, you can fill any bottle with multiple charging sessions. I filled a 66 cu ft bottle with it for my PCP air rifle addiction. It takes an ungodly amount of sessions to do that from 0 psi, but it will do it just fine if you monitor temps and give it adequate time to cool off in between. Recharging the bottle after a pretty good day of shooting ( 300 ish shots through multiple different rifles, nothing over a .357) is typically 4 or 5 sessions spread over a 1 or 2 day time span. I run it for about 20 minutes the first time on the 20 oz tipman bottles I have (from 0 psi) and then let it cool off and finish the 3000 psi with about another 10 minutes of run time. It heats up faster when the pressure is high already, so watch the temps. It charges my Mega Pitbull Bulldog from 1500 to 3000 psi in about 12 minutes. Charges my Hatsan PCPs from 1000-1500 to 3000 psi in about the same time. Charges the Umarex Origin in about 8 minutes or less depending on current rifle pressure. It needs to be rested and cooled pretty much after each rifle unless it's just a light top off.It's not quiet. At all. There's a high volume fan that runs to keep it cool and it screams like a jet turbine while it is running. The pump itself isn't bad on noise level, it's similar to some of those 12 volt compressors you plug into your cigarette lighter in your car, except the stroke is a little slower. Between the pump and the fan running at the same time, you definitely want it in a room far away from where you are.I took mine apart to see how it was made and see what I could do for tweaks. Inside is a 12 volt motor from the little razor scooters they sold something like 15 years ago that had a little chain on it going to the rear wheel. I am confident that if it ever fails, replacements can be gotten for extremely cheap ($30 ish on amazon right now). Its attached to what looks like a 1.5" (ish) air cylinder with 4 ports. 2 ports are linked together with a copper tube, 1 is the inlet with a little bronze/brass filter, and then the outlet connected to the manifold with another short piece of copper pipe. The manifold has a pressure gauge that's not in PSI, but glows in the dark when hit with bright light. The outlet nipple is one of the ones with an oring on the threads where it is screwed in. The vent valve is a typical bolt type with a flat side to release the air without removing the bolt. I really wish it had a light to illuminate the pressure gauge, but it's no big deal. I replaced the gaauge with a pcp psi gauge anyway. I also have a pressure gauge with the wiring to to be able to turn the pump off at a set psi on the way from China that I will wire in. There is a cheap temperature monitor on it with a cheap little temp sensor. If this ever fails, again a quick search turns up many for under $5. I will install a 3rd switch to be able to power up the temp monitor without turning on the fan next. The temp sensor had been zip tied to the under side of the cylinder right where the fan would blow on it. I moved it to the top of the cylinder to more accurately reflect cylinder temp and hopefully preserve some life of the pump. It definitely showed higher temps faster than where it was at.When I first got it and was filling rifles and tanks at 3k psi, I would disconnect the hose with roughly 100 psi still in it after I opened the bleed valve to remove the rifle. When I did this, the burst of air that comes out was laden with moisture. To get rid of as much moisture as possible on the infeed side, I bought a blue, empty, home drinking water filter housing that typically goes under the sink and a gallon jug of desiccant. I removed the brass/bronze inlet filter on the cylinder and replaced it with a hose quick connect, put another matching connector on the filter and attached the hose between both. This dramatically reduced the amount of moisture from the hose after a charge. I then bought the black forty dollar 40 mpa filters to use on the exit side of the compressor, a couple of the short, blue aluminum filters for $20 and cannot detect any moisture going to the tank or rifle now. I use the big ones on the bottles and the full filling of rifles, the blue ones on top offs.Using oil less / greaseless compressors keeps the oil and grease out of the outflow of the compressor. You will need to filter the outfeed regardless of compressor type to get either water or grease / oil, so filters would need to be bought with any system you use. I really don't recommend using these compressors and filters for breathing air. While I'm sure many people have and have not had any issues, I did a little research into it and I'm not killing myself or destroying my lungs to save a few ten dollar bills.I have not used the other types of compressors, but I can carry this one with me in the truck if I have to, where as almost every other one I saw needed 120 volts. The other 12vdc compressors are essentially the same as this one, just more expensive and laid out a little differently, but will encounter the same issues I did. Moisture being the most prevalent on higher pressures. Moisture inside PCP rifles is a big no no.For the two hundred seventy five dollars they are charging for it, it is absolutely worth it. I actually bought a second one to make sure I have a spare if it quits, so that I could fill multiple rifles at once, or I could continue to fill while the other one cools off. I am modifying it the same way as the first one.

Works Great!!!Pressurized my PCP quickly!

I bought this several months ago to fill up my new PCP air gun, and it easily filled a cylinder up to 4000+ pounds of pressure. The videos that are accompanying this item are essential to watch and I also recommend getting the blue filter that is mentioned in the video. I also recommend having a small fan to blow on the compressor when you’re forced to fill the air gun in warm temperatures. I also recommend getting the Warranty, as mentioned.

I purchased this for use with my Benjamin Pioneer Airbow. It does exactly what is says it will do. I took about 10 mins to pump up from zero to 3000 psi. Take notice the pressure gauge is in MegaPascals and not KPa. As long as you use it properly it should continue to be dependable. Also don't forget to leave the fan on after use to cool the internal components of the compressor back down. I don't think mine got hotter than like 45 degrees Celsius but i still left the fan on and cooled back down to room temperature. Not a bad buy for $140 thats for sure.

So pretty easy to use but the problem I have is the fan don't always turn on the fan has to work or it will over heat fast but when it works its good so maybe make sure your fan turns on.
