This manual provides detailed instructions for setup, operation, and maintenance.
2. What's in the Box
- 1 x TELESIN Magnetic Phone Cooler Pro
- 1 x Magnetic Piece (for smartphones without built-in magnetism)
- 1 x Type-C Cable (1.5m dual Type-C ports)
- 1 x User Manual

3. Setup Instructions
3.1 Attaching the Cooler (for iPhone and MagSafe-compatible devices)
- Before attaching, rotate the top part of the cooler counterclockwise upwards until you hear a "click" sound. This aligns the magnetic ring with the cooling surface.
- Align the TELESIN Magnetic Phone Cooler Pro with the MagSafe area on the back of your iPhone or MagSafe-compatible device. The cooler will magnetically snap into place.

3.2 Attaching the Cooler (for Android and non-MagSafe phones)
If your smartphone does not have built-in magnetism (e.g., many Android models), use the included magnetic piece:
- Remove the adhesive backing from the magnetic piece.
- Carefully paste the magnetic piece onto the rough back of your phone or onto the back of a frosted phone case. Ensure it is centered for optimal contact.
- Once the magnetic piece is securely attached, you can then magnetically attach the TELESIN Magnetic Phone Cooler Pro to it.

3.3 Power Connection
The cooler requires external power to operate. Connect the included Type-C cable to the cooler and then to a power adapter.
- It is recommended to use a Type-C fast charging adapter with a power output of 30W or more for optimal performance.
- For the wireless charging cooling fan model, a 27W fast charger is required.
- Using a low power adapter (e.g., standard 5V-1A) may cause the light to come on without the fan rotating or significantly reduce the heat dissipation effect.

4. Operating Instructions
4.1 Digital Display and Modes
The TELESIN Magnetic Phone Cooler Pro features a digital display that shows the real-time temperature of the cooling surface. Ensure the cooling panel is facing up to view the digital display correctly.
- L1 Silent Mode: This mode provides effective cooling with minimal fan noise, ideal for voice chats or quiet environments.
- L2 Enhanced Mode: This mode offers maximum cooling performance for demanding tasks like intense gaming or prolonged live streaming.

4.2 Cooling Performance
The cooler can drop to -9°C (17.6°F) within 1 minute and achieve rapid ice-up. It is designed for strong and efficient cooling, capable of reducing phone temperature by 10°C in approximately 7 seconds (based on TELESIN lab tests).

4.3 Usage Scenarios
The TELESIN Magnetic Phone Cooler Pro is versatile and suitable for various applications:
- Gaming: Prevents performance throttling and lag due to overheating during extended gaming sessions.
- Live Streaming/Vlogging: Maintains optimal device temperature for stable broadcasts and video recording.
- Outdoor Activities: Can be used with compatible accessories like neck mounts for cooling during outdoor use.

5. Maintenance
- Keep the cooler clean and free from dust to ensure optimal airflow and cooling efficiency.
- Use a soft, dry cloth to wipe the surface of the cooler. Do not use liquid cleaners or abrasive materials.
- Avoid blocking the air vents during operation.
6. Troubleshooting
- Cooler not turning on or poor cooling: Ensure you are using a power adapter with sufficient wattage (30W or more recommended). A low-power adapter may cause the indicator light to turn on but the fan may not rotate or cool effectively.
- Cooler not attaching securely: For non-MagSafe phones, ensure the magnetic piece is properly installed and centered on the back of your device or case. For MagSafe devices, ensure no obstructions are between the cooler and the phone.
- Digital display not visible: Ensure the cooling panel of the device is facing upwards when connected to power to correctly view the digital temperature display.
