rrn124 Posted November 1, 2007 Share Posted November 1, 2007 I've searched this forum and also the Garmin site without luck. Does anyone know the exact specifications on input voltage to the Vista Cx. I purchased a non-oem 12v car to USB converter and measure the voltages (dual port) at 5.53V (5.4V with a 300mA test load). Normal USB specs I've seen put the tolerances from 4.75 to 5.25V, so my device is over the spec. I'm assuming Garmin has a buffer zone built in, but don't want to chance it till I have some hard facts. Thanks in advance!! Randy Quote Link to comment
+Chuy! Posted November 1, 2007 Share Posted November 1, 2007 I do not know. I have two USB-DC adapters from Walmart ($10 each) and use them for my Vista HCx and Venture Cx. I've left them on overnight and have taken long trips, and have not encountered any problems - knock on wood. Quote Link to comment

My old Garmin 45 could handle voltages from 4 to 40 volts DC. Quote Link to comment
