Revolutionary Cooling: Compact, Efficient, and Practical with the OnePlus Phone Cooler

The evolution of portable phone accessories takes a new turn with OnePlus‘s introduction of the Ice Card Mini, a magnetic phone cooler designed to cool your phone effectively without the bulk. The new gadget, launching alongside OnePlus’s next phone on October 12, refines the concept of phone cooling with a sleek, card-like design that simplifies attachment via magnetic force.

The Ice Card Mini measures just 2.8 by 2.1 inches (70mm by 53.4mm) and weighs a mere 1.8 ounces (50 grams), making it approximately 30% smaller than its predecessor, the Magnetic Ice Cooling Clip. It integrates a thermoelectric cooling chip with an air-cooling system, powered directly through the phone’s USB-C port.

For another compact tech solution, Razer’s Prio Controller offers mobile gaming on the go with a foldable, portable design.

The Advanced Technology Behind the OnePlus Phone Cooler

A thermoelectric (Peltier) cooler plays the central role by shifting heat away from the phone’s hot zones. The Mini uses a ceramic sandwich design to manage heat, complemented by an air-cooling mechanism. Constructed from polycarbonate and aluminum alloy, it maintains a thickness of just 0.38 inches (9.7mm), expanding slightly around the air intake. This cooling system operates at a quiet 25-35 decibels.

This efficient setup requires only 3.5 watts of power, drawing through a standard USB-C connection. The simplicity of its power requirements means it’s suitable for use with multiple power sources, making it an excellent phone accessory.

Simplicity and Functionality Combined in the OnePlus Phone Cooler

The OnePlus Ice Card Mini’s minimalist design includes a single status light and devoid of unnecessary RGB lighting, favoring utility over flashy aesthetics. Included is a magnetic plate to accommodate phones lacking built-in magnets, broadening its compatibility, including iPhones and other Android devices.

A Versatile Accessory for Extended Use

With a 10,000mAh power bank, the Ice Card Mini can operate for up to eight hours, supporting long gaming sessions or flights. This extends its functionality beyond gaming, positioning it as a reliable travel accessory. OnePlus continues to innovate in phone accessories, reflecting a keen understanding of consumer needs for efficient, compact solutions.
