I agree with you totally on pretty much every sub $1200 small compressor out there including some of the large / high dollar ones like the Hill / Air Venturi EC300 that is rated for only 300 BAR / 4350 PSI. Most of the advertising on the Hill doesn't even mention going over 3000 PSI with it. After 5 tank fills from Zero on my $199 Yong Heng clone, I am abandoning that idea. The needle barely moves once I hit 300 BAR.
The GX CS4 he is buying is a major departure from all the current compact compressors out there as well as some of the big boys. He won't be pushing it anywhere near the "Max" to fill his tank or gun to 4500 PSI and he only has to do it once. It has a 4 stage pump, liquid cooled, never gets too hot in use and is designed for filling to 400 bar / 5800 PSI. It should fill that tank easily without straining or over heating as long as you stay under the
I will let you know once I have one how well it works to fill a tank from zero to 4500 PSI. Filling at a shop isn't an option for me as there is nothing within 100 miles and they charge $20 to fill to 4500 PSI. I would need to go there almost every week plus adding on the cost of gas, time and miles on my vehicle costing me well over $2000 a year. I am not going to spend $2000 - $5000 on a compressor when $600 will get the job done fast enough for my needs.
