The weather is getting hotter, and when playing games on my phone, it tends to heat up a lot, followed by system lag and unstable signals. So I had to buy a phone cooler. This time, I got the Nubia Red Magic 4 Pro Cooling Back Clip, which has a compact and portable body, plug-and-play capability, and compatibility with multiple devices. This cooling back clip adopts a turbo cooling method with a maximum output power of up to 27W. It also introduces the Redmagic Ice 4.0, the fourth-generation semiconductor cooling technology from Red Magic, which can cool down the temperature to as low as -7 degrees Celsius. Let's take a look at the product.

The Nubia Red Magic 4 Pro Cooling Back Clip features a mecha esports design with a cool and stylish pure silver coating. It not only brings a strong metallic texture but also has a delicate touch. It exudes a hardcore style and a full sense of technology. It is equipped with a 7-blade high-speed fan with a maximum speed of 4500 RPM, providing powerful cooling. With innovative design turbine cooling fins and an efficient air duct for delivering airflow, it achieves higher cooling efficiency. In addition, the back clip incorporates a cool RGB intelligent temperature control light effect. The light effect changes colors based on temperature, creating a soft and atmospheric ambiance during gaming. The Nubia Red Magic 4 Pro Cooling Back Clip has a non-slip rubber design on the back, which tightly adheres to the back of the phone, enhancing the cooling capability.

The Nubia Red Magic 4 Pro Cooling Back Clip has a mechanical button on the back for quick mode adjustment. It features a Type-C power slot. It adopts the Redmagic fourth-generation semiconductor variable frequency cooling technology and is built with custom TEC semiconductors and a heat separation design. It effectively blocks heat backflow, improves cooling efficiency by 20%, and provides long-lasting cooling with variable frequency regulation. The back clip has a bi-directional stretchable design, capable of clamping devices with a width range of 68-90mm.

The Red Magic 4 Pro Cooling Back Clip is designed with upward and downward airflow to prevent hot air blowing onto your hands during gaming. It uses a direct current power supply method and is compatible with mainstream fast charging protocols such as PD and Qualcomm's QC. You can connect it to the phone's USB-C port or use a power adapter, or even power it with a power bank. Its RGB light effect adjustment is beautiful, and the cooler's ambient light color changes automatically based on the temperature. After attaching the Nubia Red Magic 4 Pro Cooling Back Clip to the phone, it starts cooling almost instantly. Previously, when not using the back clip, the back of the phone would get extremely hot, and sometimes the game screen would stutter. After using this Red Magic 4 Pro Cooling Back Clip, not only did the temperature drop significantly, but also when removing the back clip, both the phone and the back clip felt ice-cold to the touch. Ice formation can even be observed when removing the cooling back clip.

Overall, the Nubia Red Magic 4 Pro Cooling Back Clip has a cool appearance with a hardcore mecha-style design, dynamic RGB lighting effects, a 7-blade high-speed fan, custom TEC semiconductors, and the Red Magic fourth-generation semiconductor variable frequency cooling technology. When playing high-frame-rate games, the heat dissipation is significantly reduced, ensuring high playability and delivering high-performance output for an enjoyable gaming experience.
