OnePlus is shrinking its phone cooling lineup with the Ice Card Mini, a 50 g (1.8 oz) magnetic cooler that pairs a thermoelectric cooling chip with an air-cooling system in a body smaller than a standard bank card. The accessory measures 70 x 53.4 mm (2.8 x 2.1 inches) and just 9.7 mm (0.4 inches) thick, making it roughly 30% smaller in footprint than the 68 g (2.4 oz) Magnetic Ice Cooling Clip that OnePlus launched in March.
The Ice Card Mini connects over USB-C and draws up to 5V at 0.7A, meaning it can pull power directly from the phone it is cooling, from a power bank, or from a wall adapter. OnePlus claims a 10,000 mAh power bank can keep the cooler running for up to eight hours on its high setting. Two fan modes are available, rated at roughly 25 dB and 35 dB, with an LED status light that glows blue or green to indicate the active mode and flashes red if something goes wrong. A magnetic plate included in the box adds compatibility with Android phones and iPhones that lack built-in magnets, while OnePlus and OPPO devices can pair the cooler with ColorOS X's high-performance mode.
OnePlus will reveal the Ice Card Mini alongside the OnePlus 16 at a launch event on 2026-10-12. Pricing has not been announced, though the predecessor debuted at 179 yuan, roughly $25 (€23).
