OnePlus has introduced a new accessory aimed at managing smartphone temperatures during intensive use, positioning its Magnetic Ice Cooling Clip as the thinnest magnetic smartphone cooler currently available. The device was announced alongside the OnePlus 15T and is priced at 179 yuan (around $26), placing it in the more affordable segment of mobile cooling accessories.
The design is notably compact, measuring 9.8mm at its thinnest point and weighing 68 grams. Its overall footprint—87.6 x 62 x 9.8mm—keeps it close to the size of a small power bank, making it relatively unobtrusive when attached to a phone. Some structural elements extend slightly thicker, up to 11.9mm, but the general emphasis is on portability and minimal bulk.
At its core, the cooler relies on a thermoelectric cooling (TEC) module, a technology commonly used in similar accessories to actively transfer heat away from the device. OnePlus pairs this with a curved air duct system and a centrifugal fan designed to manage airflow more efficiently. Cool air is directed in from the top while hot air is pushed out from the side, a layout intended to reduce discomfort during prolonged gaming or media use.
The Magnetic Ice Cooling Clip offers two operating modes. A silent mode lowers fan noise to around 22dB, making it more suitable for quieter activities like video streaming or photography. Performance mode increases cooling output, with noise levels rising to approximately 36dB, targeting users running demanding applications or games for extended periods.
Attachment is handled through a magnetic system rated at up to 10N of force, allowing it to work with compatible Android devices and iPhones. This approach avoids clips or brackets, though effectiveness may vary depending on device compatibility or case thickness. The cooler also includes Bluetooth support, enabling additional controls through OnePlus’s ColorOS interface, though its usefulness will likely depend on how widely those features are supported across devices.
Power is supplied via USB Type-C, with a maximum input of 5V/3A. The build combines polycarbonate and aluminum alloy materials, balancing durability with weight. An integrated indicator light system provides basic status updates during operation.
The release comes amid growing competition in the mobile cooling space. Brands like Black Shark and Red Magic have recently launched alternatives with different priorities, including higher cooling power, integrated displays, or more aggressive styling. In comparison, OnePlus appears to be focusing on portability and ease of use rather than pushing maximum cooling performance.
As mobile gaming and high-performance applications continue to push hardware limits, accessories like this reflect a niche but expanding category. While not essential for everyday users, compact cooling solutions may appeal to those looking to maintain consistent performance during longer sessions without significantly increasing device bulk.
