Black Shark Magnetic Cooler 4 Pro

The Black Shark Magnetic Cooler 4 Pro is a high-performance smartphone cooling fan designed mainly for gaming and heavy performance use, especially when your phone heats up during long sessions.

It uses a 27W high-power TEC (thermoelectric cooling) system, which actively lowers the temperature of your device instead of just blowing air. This allows it to significantly reduce overheating during gaming, streaming, or recording.

The cooling performance is strong, with the ability to reduce temperatures by up to 40°C under ideal conditions, helping prevent FPS drops, thermal throttling, and battery overheating during intensive use.

It attaches using a strong 12N magnetic system, meaning it sticks firmly to compatible phones or magnetic plates and stays stable even during movement or gaming.

The design includes top and bottom air vents, which helps direct hot air away from your hands for more comfortable gameplay. It also features RGB lighting effects that can be customized for a gaming setup look.

For safety, it includes dual NTC temperature protection, which automatically shuts the device off if temperatures go too high or too low, protecting both the cooler and your phone.

It is also widely compatible, working with smartphones, tablets, and devices using either magnetic attachment or clip-on accessories.

Overall, it’s designed for users who play heavy games or run demanding apps and want stable performance without overheating or lag.
