Do not run for periods and it will last some time.
a nice compact airgun pump unit, tops up my tank in about 3-4mins, time will tell just how well it will work in a year or two, but saying that I'm very pleased up to now. I should have added the extended warranty.

Great item
Great compressor I don’t like the fixed wires I like cordless so I modded mine I replaced the wires to a Socket and fitted a buck converter and now it runs of a dewalt battery and mains and car battery And no wires

Nice piece of kit
Nice air compressor—not too loud but not silent either. It fills my Gamo PCP from nearly 0 to 200 bar in less than 8 minutes. Pros: Good price. Cons: Poor instructions, but great after-sales support. I usually email them, and they respond by the next day. I recommend it! P.S. When doing your first test, keep a close eye on your gauge—within 10 seconds, it can hit 3000 PSI. I blew the main seal the first time, but the built-in safety worked as intended. The burn disc is easy to replace, and spare parts are included in the package.

Easily portable and well constructed
I read many reviews before deciding on this one, and to date I have only used it a few times so far. It was easy to figure out how to use luckily, as the instructions make no sense! It's quite portable and seems well constructed. I filled my Daystate Harrier X after just a few minutes. I have not tried it direct from the car battery yet, but will do soon and see how it performs. Noise is not as bad as I was expecting, it sounds like a little tug boat! All in all, I'm very pleased with it.

Reliability
The few times I’ve used it, it’s been excellent. There is one drawback for me but may not cause others a problem is that most PCP air rifles quote bar for fill pressure, the gauge is very small and is in PSI so I have put stickers on side of machine with the converted pressures. Also there isn’t a temp gauge so if you have access to a laser temp gauge is useful to have to hand. None of these observations are causing me a problem.

Fantastic
Great generator best on market but one star not for supplier but for the delivery. It was dropped over my fence left on show and in the rain. Not where I ask it to be left

Great pump and great service.
After debating for months and watching reviews I eventually went for this and only having had it a week and used it just a couple of times, I'm super happy with it and the service from the seller. Time will tell how well it lasts, but initial thoughts are very positive. The pump is actually smaller and quieter than I expected, but also pretty fast at filling up a PCP gun chamber. Mine came with a gauge in MPa which I didn't like and the company simply offered to send me a new gauge in PSI for free. Fast and responsive answers to questions. Good service and happy with the product in the short time I've had it.

Fijne compressor
Fijne compressor. Ik had eerst een compressor van vevor. Deze was binnen 6 maanden kapot. Deze ziet er kwalitatief veel beter uit. Hier heb ik veel meer vertrouwen in! We gaan het zien!

Compressur haute pression pour PCP
Parfait pour recharger une carabine PCP ou un lanceur Paint Ball. Fini la corvée de rechargement avec la pompe manuelle ! Il faut bien prendre le temps de lire la notice. Il faut surtout vérifier le niveau de tension d'entrée du convertisseur 220V/12V. Il semble que par défaut il arrive sur 110V... Pour le reste, très facile d'utilisation

Works great for PCP air rifles
This is my second pump. First one was A CS-1 That quit working on the third refill... So far on this one I have filled my air rifle 3-4 times With no issues.. It was completely packed in Styrofoam For shipping, happy about that... Comes with a bunch of spare parts but no Instructions on where that go or how to install them... Seems like all these pumps are overpriced Chinese junk. But this one seems pretty basic in It's design and build.. When using, I only let it run until it gets hot enough. Where I can't keep my hand on it.. Roughly around 8 -10 minutes. And then let it cool for 5min.. Took hours to fill a Scott air pack 30 minute bottle. There is a port on the front cylinder to add grease I highly recommend doing so seems like the grease they used isn't very good ..But do not overgrease. Time will tell. As for now, I am happy with this purchase...Recap: 11/27..I've had this pump for a few months and so far has worked flawlessly..it will fill to 4500psi although it pumps mouse farts so to fill a bottle or scuba tank is an enduring process but it will do the job..I use it for a pcp air rifle..oh and it is already setup to run off a 12v car battery..great little pump at a fair price two thumbs up as Siskel and Ebert would say 👍👍
