Nubia Magnetic Cooler Smartphone Cooling Fan with Semiconductor Refrigeration, RGB Lighting, Bluetooth App Control, USB-C, Black

Forget passive phone coolers that just move warm air around—the Nubia Magnetic Cooler actively chills your device using a semiconductor refrigeration plate, dropping surface temperatures by up to 25°C. This makes it ideal for sustained gaming sessions, 4K video recording, or fast charging where heat can throttle performance and degrade battery health. Its MagSafe-compatible magnetic mount snaps onto compatible phones in seconds, while the included sticker extends compatibility to nearly any smartphone.

Highlights

• Semiconductor (Peltier) cooling with up to 20W theoretical cooling power
• High-speed 7-blade fan spinning up to 7200 RPM for rapid heat dissipation
• Magnetic attachment: works with MagSafe iPhones or any phone via included magnetic sticker
• Customizable RGB lighting with Bluetooth 5.0 app control via RedMagic Studio
• Quiet operation under 30 dB, so it won't disturb your gameplay or calls
• High-conductivity ceramic cooling plate and 3000 mm² heat dissipation area
• Powered by USB-C (9V/2A, 18W max) with 1.5m USB-C cable included

In daily use

Attach the cooler to the back of your phone, plug it into a USB-C power source, and feel the difference within minutes. The 30 x 30 mm semiconductor cooling area targets the hottest zone—usually near the processor—while the aluminum alloy body and silicone padding ensure a secure, scratch-free grip. The fan's PWM support adjusts speed based on cooling demand, balancing performance and noise. Use the RedMagic Studio app to switch lighting effects, monitor cooling status, and fine-tune fan profiles.
