Problem
The Corsair Harpoon Wireless Mouse uses a built-in rechargeable battery. If not charged properly, the mouse may power off mid-use, fail to connect wirelessly, or experience reduced performance.
Solution
You can charge the Corsair Harpoon Wireless Mouse using the included USB cable, which also allows you to keep playing in wired mode while charging.
Step-by-step instructions
Charging the mouse
- Locate the USB charging cable included with your Corsair Harpoon.
- Plug the cable into the front charging port of the mouse.
- Connect the other end of the cable to a USB port on your PC or a powered USB adapter.
- The mouse will begin charging automatically.
Confirming charging status
5. Check the LED indicator near the scroll wheel:
- Solid or pulsing light = Charging
- No light (and battery level full in iCUE) = Fully charged
- Open iCUE software to see the exact battery percentage.
Playing while charging
7. The mouse functions as a wired mouse while connected via USB.
8. Continue using it normally while the battery recharges.
Optional methods or tools
- High-power USB port (USB 3.0/3.1): Charges faster than older ports.
- Powered USB hubs: Useful if your PC’s ports are limited.
- iCUE software alerts: Can notify you when the battery is fully charged.
Best practices or tips
- Plug in the mouse when the battery reaches around 20% to avoid sudden shutoffs.
- Use wired mode for long sessions — this keeps the battery topped up while gaming.
- Avoid fully draining the battery too often, as this can shorten its lifespan.
- Keep the charging cable accessible so you can quickly switch from wireless to wired when needed.
