Methods for charging the GPSMAP 620 or 640

There are two ways to recharge the battery of the GPSMAP 620 and the GPSMAP 640. The marine or automotive mount will recharge the battery as long as the mount is connected to a 12V DC power source. The other alternative is to use the AC house charger.

While the GPSMAP 620 and GPSMAP 640 can be connected to a USB port on a computer, it will not charge the battery as the USB port on computer only outputs 5V DC and these units require 12V DC to be able to charge the battery.
