6. Operating Instructions

The TUNNU Magnetic Wireless Charger with Phone Cooler operates automatically once connected and attached to your phone.

• Automatic Activation: The cooling fan and wireless charging function will begin when the device is powered and magnetically attached to a compatible smartphone.
• Cooling Performance: The semiconductor refrigeration technology works to draw heat away from your phone's back surface, while the fan dissipates this heat into the environment. This helps prevent performance degradation due to overheating.
• Optimal Use: For best cooling results, ensure the phone cooler's fan vents are not obstructed. This is particularly important during extended gaming sessions, video streaming, or other high-performance tasks.
