OnePlus has announced the Ice Card Mini Magnetic Cooler, a compact accessory combining thermoelectric cooling with active air circulation. The unit weighs 50 grams and attaches to mobile devices using a magnetic system with 10 N of holding force. Full availability will align with the upcoming launch of the OnePlus 16 flagship smartphone.
The cooler measures 70 millimeters long, 53.4 millimeters wide, and 9.7 millimeters thick, expanding to 12.3 millimeters around the air intake vent. Total weight sits at roughly 50 grams. OnePlus built 2 cooling settings into the unit. Quiet mode generates approximately 25 dB of sound, while performance mode reaches up to 35 dB during heavier workloads.
Magnets secure the accessory to compatible phones with 10 N of force. OnePlus includes an adhesive metal plate in the box for devices lacking internal magnetic rings. The cooler draws power through a USB Type C port directly from a connected smartphone, a wall adapter, or an external power bank. A standard 10,000 mAh power bank provides up to 8 hours of continuous operation at maximum output.
