Learn how to charge your Fenix rechargeable lights with the 2-in-1 USB cable, including step-by-step instructions and common mistakes to avoid.

Quick Answer

To use the Fenix 2-in-1 USB Charging Cable, plug the USB end into a power source, then connect the appropriate split end to your Fenix light. You can charge one device at a time or two devices simultaneously using the Type-C and Micro USB ports.

Why Choose the 2-in-1 Cable?

The Fenix 2-in-1 USB Charging Cable is designed to charge all Fenix rechargeable lights, making it a versatile replacement or backup cable. Its split design lets you charge two devices at once, which is handy when you have multiple lights or a light and another device needing a charge.

One trade-off to note: this cable cannot transfer data. It is strictly for charging, so don't expect to use it for syncing or file transfers. If that's a need, you'll need a different cable.

Understanding the Port Types

The cable splits into two ends: one USB Type-C and one Micro USB. This covers most Fenix rechargeable lights, but always check your light's charging port to ensure compatibility. If your light uses a proprietary port, this cable won't fit.

Step-by-Step Guide to Using the 2-in-1 USB Charging Cable

Check Your Light's Charging Port: Inspect the charging port on your Fenix light to determine whether it uses USB Type-C or Micro USB. This ensures you use the correct split end. If your light doesn't have either port, this cable won't work—check compatibility before purchasing.
Connect the Cable to a Power Source: Plug the standard USB end of the cable into a USB power adapter, power bank, or computer USB port. Ensure the power source is working and provides sufficient output. A low-output port may charge slowly; use a wall adapter for faster charging.
Connect the Appropriate Split End to Your Light: Insert the Type-C or Micro USB connector into your Fenix light's charging port. Make sure it fits snugly and is fully inserted to establish a connection. A loose connection can interrupt charging—always verify the connection is secure.
Charge One or Two Devices Simultaneously: For one device, leave the other split end unused. For two devices, connect both the Type-C and Micro USB ends to compatible devices at the same time. Charging two devices at once may split the power output; expect slower charging for each.
Monitor Charging Progress: Watch for the indicator light on your Fenix light (if available) to turn green or off, signaling a full charge. Unplug once charging is complete to avoid overcharging. Don't leave the cable connected indefinitely—unplug after charging to preserve battery health.
