If you read any review read this one. I did have problem with this compressor and got in contact with the company rather than just returning it because I have friends that own this product and love it. They were very good about staying in touch with me. In fact I was a little slow on my side in the communication. It was hard to believe it was a Chinese company. Guess we need to stop thinking there are only cheap or bad companies in China. Just like here in the US there are bad and good companies. I almost put my personal email on the text just to prove I am a real customer but since everyone can see it I did not. In stead of sending me parts to replace, They sent another unit to me direct. This item is not cheap and told me to just keep the old unit which I could get fixed maybe but will just use for parts at some point. Things are changing in China.

very good

Glad to have this PCP Air Compressor with a 350W motor, and it’s been really solid for filling my air rifles. The 4500Psi max pressure is no joke, it handles the job quickly without overheating or slowing down. What I really like is that you can power it with your car’s 12V DC, which makes it super convenient when I’m out and about. It’s compact but powerful, and I haven’t had any issues with it yet. The setup was pretty simple, and it’s been running smoothly every time I’ve used it. Definitely recommend it for anyone who needs a reliable compressor on the go! Also noteworthy is the solid build quality which really seperates it from the competition. Great value also.

I like how portable this PCP Air Compressor is, and it's got lot's of power. It's got a 350W motor, and 4500psi/30Mpa. AC/DC power. I got this air compressor for my nail gun and paint sprayer. It's easy to work with, even though is kinda loud. I like it.

I got this to use in my card for charging an air venturi 3k psi bottle on a mpx gen 2 and it works perfect. I set the top gauge to stop at 3k and press the start button and it starts filling up. It takes like 5-10 minutes from empty to full on this small tank but it works. It's just way too loud though. I wish some thought went into the noise of these things when they designed it. It's like they did but went for the loudest parts they could find. The fans are loud but not deafening like the I guess air pump. This thing is much louder than the air gun I'm filling up with it. I guess the sound is expected and this works like it should so it still gets 5 stars.

This product may be mostly a failure of instructions as they are a bit vague. The unit has error codes but the manual doesn't list what any of the error codes mean. The product page gives a 50 min fill time for a 2L but elsewhere says 1.5L max. It says if the temperature gets above 80C you must manually shut it off, which is a bit annoying on a tank with auto-stop at the right PSI. High pressure tanks are no joke they can fail and injure or kill you. I think it is not a great idea to use these in ways the manual doesn't explicitly cover but as it is light on some of the details here is what I believe is true:*) Despite some things saying to start it with no pressure, it means no pressure in the fill line itself. This means your bleed valve should be opened when hooking your tank up, or before resuming a fill session.*) The machine shuts off after a 30 minute session no matter what, and by shut off I mean the compressor not the fan. The fan runs as long as it is plugged in.*) You can fill a tank over multiple session or refill a partially filled tank. The process is the same as normal but if you haven't disconnected the tank from the machine between sessions you still must open the bleed valve to relieve line pressure before resuming.*) Even if you fill a small tank, at a low temperature in under the 30 minute max session time the system throws an "E4" error when done. As mentioned the manual does not cover what the error messages mean, but I believe E4 is 'success' (no idea who's bright idea it would be for E4 to somehow be the expected message)>*) Given the ominous warning about the temperature requiring manual intervention I would be weary of running anything that gets you close to that temperature unless you want to sit and babysit the unit. I haven't seen the temperature change more than 20 degrees in a 30 minute session but your experience may vary*) The manual states it should be serviced every 50 fills of a 50cc bottle (or equivalent) it also says to only have it serviced by someone with professional guidance. The manual is very detailed on fully servicing it however, so that is a plus (if you deem yourself professional).*) When you are done filling, prior to removing the tank, you must open the bleed valve*) You could, in theory, fill any size tank but it will take a long time.Again, not all of these things are stated in the manual so don't take some random strangers advise on something this critical. I believe the above however are 'as designed' and not exceeding what it is meant to do.The unit is noisy and takes awhile so being able to walk away would be a plus. The PSI gauge seems to be pretty close to matching the tank regulator. The moisture filter is the large item at the end of the fill hose (should be closest to the tank) it has foam inserts to absorb water from the compressor. If you are doing some large fills you may want to open it up to check how wet it is. You want to avoid moisture into the tank whenever possible.This is an oil free unit (meaning it doesn't require an oil reservoir to work but some parts are oiled). It is critical to keep oil away from the air path as best as possible. The filter (should) filter out potential oil but you _really_ don't want oil to get into a HPA tank. Oil under pressure can essentially combust from pressure alone. For the parts of this unit they recommend silicone or motor oil. I highly recommend silicone it will not combust in the same way motor oil would.If you are adhering to the letter of the manual I would not plan to use over multiple sessions, then again the manual doesn't even mention using the bleed valve when done so to each their own.
