Default How much refrigerant does it take to fill up the A/C?

I've noticed my A/C has been blowing warm air. Checked the pressure on the low-side port and it was low (about 17psi) so I bought an 18 ounce of R-134A refrigerant to recharge/refill AC.

The can is almost empty but the gauge went up only about 9psi at first and then stopped at 28psi which is low for temperatures around here it needs to be at 45psi. Does it really take more than 1 large can to refill?

The fill spot is in the right corner of engine compartment near the firewall... the high port and low port are both there u need the thicker tube.
