They are slow, cheapo depot, weak, and low quality. You are wasting your money to buy one.

Suit yourself, it won't take long for it to burn out.

I've actually had luck with a 280psi compressor that was built into a car jump starter pack.. It has filled over 100 times to 200+ PSI

But I still wouldn't recommend it, others probably wont be as reliable.

I have a 300PSI compressor. It failed to pressurize my chamber beyond 160PSI. It started smoking so I shut it off and popped it open to find that the pump was easily 260 degrees F. I would suggest a homemade hand pump from copper with a long stroke and narrow diameter. With effort, you should be able to get 300-400PSI. Be prepared to have arms of steel after a few shots. :lol:

Take a look at a bicycle pump. Easy way to do it is to use copper pipe. I left a design here. You may want to use a rubber stopper instead of the floating o-rings and use two check valves, one inlet and one outlet, if you want to use pipe smaller than 1/2''. 1/2'' should give up to 700 PSI if you weigh 150lbs.

I've also had good luck with that very same compressor, trick is, tiny chambers, long breaks, and never run it for more than twenty seconds without the same time for a break. It will go past 300PSI, I'd guess 340 or less, it maxes out the gauge (bad practice I know, I was pressure testing a .177 diaphram launcher).

Mine is now defunct, the hose popped off the barb at the outlet and piloted my launcher, a 1/4 hex nipple will be epoxied over the barb and a snap-air QD threaded on.

Now, I'd never consider using this on my nearly built 1 inch porting launcher, fridgy only.
