Hey guys I have an Escort Passport 9500iX and am trying to get set up to download off the internet. I purchase a 110V step down plung in converter to 12V cigarette adapter for my Escort power cord to plug into so that I can power up the unit near my PC. The converter is really a 13.5 V output and 500ma. When hooked up the Escort display continually blinks and the unit pops to each blink. Is this because the ma draw of the Escort is more than the converter is putting out?
