Two soft rubber positioning caps are included to hold any watch at the optimal focal distance from the LEDs, ensuring maximum charging efficiency. These caps stabilize the watch and maintain consistent alignment with the light source, which is critical for effective solar charging.

Important Notes
Avoid unverified “turbo” chargers that generate excess heat and can damage internal solar cells. CoolFire is specifically designed to protect sophisticated solar mechanisms from long-term harm. Do not use with non-solar watches. Always place the watch face directly under the LEDs using the provided caps for best results. Clean the charger surface regularly to maintain optimal light transmission.
