Compressor tank will only fill a portable tank half way
by Stephan Smith

I have a small compressor and tank that has a gauge showing about 110 psi when it auto shuts off...no problem there.
I recently bought an inexpensive portable pressure tank (5 gal)to use to fill tires around the household, etc.
When I use the compressor tank to fill the portable, it will only fill it to half the pressure of the compressor tank.
Is there some pneumatic physical law that I'm unaware of the causes this?
The hoses on both tanks are rated to 200 psi and the portable tank is rated to 125 psi. Thanks!
