OnePlus launches pocket-sized Ice Card Mini cooler for gaming phones

OnePlus has launched the Ice Card Mini, a magnetic phone cooler that sticks to the back of a device and aims to keep phones cooler while gaming. The card‑sized accessory weighs 50 g and measures 70 mm × 53.4 mm, making its footprint about 30 % smaller than the earlier Magnetic Ice Cooling Clip, which weighed 68 g. It attaches with magnets that exert roughly 10 newtons of force and can be used on phones with or without built‑in magnets thanks to an included magnetic plate. The cooler draws up to 3.5 W of power through a USB‑C connector and combines a cooling chip with an air‑flow system to move heat away from the phone’s hottest spots. Two speed settings generate sound levels of about 25 dB and 35 dB, comparable to a whisper. The body is built from polycarbonate and aluminium alloy, is 9.7 mm thick (rising to 12.3 mm around the intake), and comes in a single Silver Wing grey finish without flashy gaming lights; a blue or green LED indicates the active mode and a red flash warns of a fault. The Ice Card Mini launches alongside the OnePlus 16 on 12 October at 7 pm local time, listed on Oppo’s China store, though pricing and US availability have not been disclosed. OnePlus says a 10,000 mAh power bank can run the cooler for up to eight hours on high mode, enough for long flights or extended gaming sessions. The accessory benefits from ColorOS X’s high‑performance mode on OnePlus and OPPO phones, and power can be sourced from the phone, a power bank or a wall adapter.

Context

Magnetic accessories have grown popular after Apple introduced MagSafe in 2020, and standards like Qi2 now support Android phones. Traditional phone coolers used bulky clamps, so the Ice Card Mini marks a shift toward slimmer, pocket‑friendly cooling solutions.
