I have owned one for about 3 weeks and must say it is great so far filling from either 120vac or 12 vdc. It has no problems so far filling a 480 cc bottle gun to 4500 psi. Takes a little longer than 3000 psi fills but does not run over 10 mins. I think if you do the regular maintenance it should last a long time. Still a lot of money for air but beats going to the scuba shop for tank refills or heart attack hand pumping.
I will probably get a negative for “ not it’s intended use “ by some busybody but I have to say that it WILL fill small pony tanks (88-90 ci) in 500 psi steps with a 5 min rest between steps to 4500 psi no problem with ending current draw (built in meter) of no more than 22. I don’t think it knows the difference in tank size but I would not push it more than 90 ci, but I don’t have to because all I own is a 90 ci Benjamin bottle. Just do more maintenance if you fill a pony tank in STEPS. And ALWAYS start at 0 psi and open your tank valve when your gauge pressure is at tank pressure.
Looks like about everyone’s sold out and back ordered on the Nomad II, might have some trouble finding one right now.
