Most modern GPS devices from major manufacturers such as Garmin come equipped with a USB cable. It’s primarily intended for connecting the GPS to a computer, enabling users to install or back up new maps, points of interest, and tracks or routes. Garmin devices with a built-in charging circuit can also trickle-charge from the USB connection, which is slow but will extend the battery life. The supplied USB cable won’t power the GPS directly, but there are alternative methods. Writer Bio
