The MarCum 12V USB Adaptor offers a solution to a host of power issues on the open ice. As a simple dongle that connects to any existing 12V battery with spade terminals, anglers can now harness additional Lithium power in their fishing electronics to charge any USB-compatible device. MarCum knows that long days on the ice sometimes require extra power to recharge a Bluetooth speaker or phone, allowing anglers to extend their day with a simple, single accessory purchase. Now you can plug your MarCum Pursuit HD L and phone into the same battery, allowing you to watch both screens on gameday. No matter the application, never be without power to the devices that matter most, no matter where you are.
