If the extra tank is clean enough to risk possible backflow, you could
connect it to your system through a check valve so it would always be
full at max pressure. A second tank mounted upside down would hold the
air if you don't have a shop compressor. I used a faucet for the
outdoor compressed air tap so I can pressurize my solar water heater
tank if necessary.

I have a collection of old pressurized water fire extinguishers for
fires in the woods etc. One or two can put a small fire out before my
cell phone finishes powering up to call 911. I only needed them once
so far, when the old guy across the street collapsed while cutting up
wrecked cars and his torch set a fire in the dry grass. I wished I had
one when his son's wood stove started a fire in the wall. (They don't
have power or water). I grabbed his kids Coke bottle, put my thumb
over the top, inverted and shook it, and sprayed the fire up in the
wall above the flue opening. Good trick to remember. The kid still
hasn't forgiven me.
