Overview

The Garmin 010-11131-10 is a hard-wire USB power cable for running compatible Garmin portable devices from a boat’s DC supply, taking 8 to 58 V DC input and outputting 5 V at 500 mA. It’s a practical way to keep a small GPS receiver or tracker powered at the helm or nav station without relying on a plug-in adapter that can loosen up in chop.

This cable is commonly used with Garmin Approach handhelds (including G3, G5, G6, and G7), the GLO GPS receiver, and the GTU 10 tracker. One end connects to the device via USB, and the power end uses bare-wire leads so you can tie it into a fused circuit.

The wide input range covers typical 12 V and 24 V onboard systems, which makes it easy to integrate on anything from a small center console to a larger cruising boat with a higher-voltage house bank.

Key features

• 8 to 58 V DC input range for direct connection to common 12 V and 24 V boat systems
• 5 V output at 500 mA for steady USB power to compatible Garmin devices
• Bare-wire leads for clean integration to a switched, fused circuit at the helm or distribution panel
• Eliminates the need for a cigarette-lighter style adapter in permanent installs
• Useful for devices that need continuous power during long runs, storage tracking, or all-day tablet navigation setups

Compatibility and fit

Confirm your device is in the supported family before ordering, including Garmin Approach handhelds (G3, G5, G6, and G7), Garmin GLO, and GTU 10. Also verify the USB connector at the device end matches your unit’s port style, since Garmin has used different USB form factors across product generations.

Installation and setup

For a tidy marine install, connect the bare-wire leads to a switched DC feed so the device powers down with the boat, or to an always-on circuit if you need continuous operation. Protect the circuit with an appropriately sized fuse or breaker close to the power source, and use marine-grade splices with heat-shrink to keep moisture out.

Route the cable where it won’t chafe on sharp fiberglass edges or rest against hot surfaces, and add strain relief near the device so vibration does not work the connector loose over time. Keep any conversion module or junction point in a dry location above potential bilge water.
