The Avenger has fill up to 4350psi with up to a 3000psi regulator which is high for less-expensive PCP. The issue is that you need a tank / compressor over 4350psi to fill it and it won't be able to fill as many times. Also, you can only accurately shoot when the tank pressure is over the regulator setting (3000psi?).
For a Benjamin Marauder Field Target, you need a 3000psi fill and it has a 1350psi regulator pressure. This means that you will get many more fills from a 4500psi tank and it will shoot accurately down to 1350psi.
Filling a rifle directly from a Yong Heng isn't a great option because of the set up time, non-portability, noise, etc. If you have a single rifle that you fill with a Yong Heng, it will not be a great experience. The Yong Heng is great for filling a medium/large tank but needs additional filtering around it.
A 97cu ft (large) tank will fully refill (3000 to 4350psi) an Avenger 5.5 times. The same tank will fully refill (1350 to 3000psi) a Benjamin Marauder Field and Target about 37 times.
In my opinion, someone starting out in PCP should get either a small compressor (Traveler, Nomad, or other oilless similar) [fill time = 5 or so minutes] or medium/large tank [fill time = 10 seconds] if they have access to an HPA air source [paintball shop that will fill it, probably ~$20-$30 to fill a large tank].
I've seen this one on Amazon that seems to have good reviews but I've not personally used it. I have a Traveler that works fine but it much slower than using a tank.

BTW - a small compressor can't easily fill a large tank. The small compressors can only run about 20-30 minutes before they turn off due to overheating. It would take many (20+) cycles of overheating/cooling to fill a large tank and it isn't good on the compressor.
