Overview

The Garmin 010-11838-00 is a 12 V vehicle power cable that plugs into a standard 12-volt accessory socket and powers compatible Garmin devices through a built-in mini-USB connection.

On a boat, it fits the same role as it does in a car: steady power from a helm outlet for a portable GPS, older navigator, action camera, or handheld that charges over mini-USB. It is a straightforward way to keep a device running on longer runs without leaning on AA batteries or an internal battery.

Use it in a protected location, route the cable so it cannot snag steering or throttle controls, and leave a little slack at the device to reduce strain on the mini-USB port while the boat is moving.

Key features

• Plugs into a 12-volt accessory port/cigarette lighter style socket for DC power at the helm or in the cabin.
• Built-in mini-USB connector for direct connection to compatible Garmin devices.
• Charges or powers the connected device anywhere 12 V DC accessory power is available.
• Commonly used with devices such as nüvi series, zumo 220 and 350LM, dezl 560LM and 560LMT, nüLink! 1695 LIVE, eTrex 10 Geocaching Bundle, and Delta Upland devices.

Compatibility and fit

This cable terminates in a mini-USB plug, so it matches devices that have a mini-USB power port. It will not fit units that charge over micro-USB or USB-C. If your boat has a 24 V system, make sure the outlet you are plugging into is a regulated 12 V accessory socket.

Installation and setup

Plug the adapter into the 12 V socket, then route the cable to the mounting location with enough slack to allow normal movement without pulling on the connector. On open boats and T-tops, keep the plug and the device connection in a sheltered spot to reduce exposure to spray and to help the connection stay clean.

Use cases on board

Handy for day boats, fishing rigs, and cruisers that use a portable Garmin unit at the helm or keep a compatible device running for hours at a time. It is a good match for boaters who want a simple power lead from a 12 V outlet without changing the boat’s wiring.

Maintenance and care

After use in a salty environment, unplug the cable and wipe it down, paying attention to the mini-USB end so corrosion does not build up on the contacts. Avoid sharply bending the cable near the plug, and store it dry when it is not in use.
