Will this cable provide external power for the GPSMAP 421s?, Rick, Ottawa
Does this allow unit to be plugged into house power outlet to power GPSMAP 421s?

This cable will wire to your boats 12V power source. To power that unit in your house it is best to use a 12V car or motorcycle battery and the cable that came with the unit. You can also use a 12V AC power source if it has a high current output. I have used the Garmin ACDC converter with the 421S before. You will need to put a cigarette lighter end on the power cable to plug into the Garmin adapter. Here is a link to the Garmin ACDC. /garmin-ac-dc-to-vehicle-adapter.html
