Thanks, Syed. My DreamCatcher 3.02Q is powered with a Chinese buck (6 to 26 volts DC in) regulator connected to a 12 volt brute-force power supply. The regulator provides up to 3A at 5.2 volts DC, very clean DC, no ripple.
My DreamCatcher 3.03 is powered with a GoalZero Sherpa power supply that is either solar-fed, or 110v to DC converter fed. Very clean DC on USB to the DreamCatcher.
