Beat smartphone overheating during intense gaming, outdoor livestreams, field photography, or daily use in hot climates with our Magnetic PCM Cooling Patch.

This lightweight passive cooling accessory is designed to attach easily to magnet-ready smartphones via a matching magnetic sticker. First, connect the PCM cooling patch to the magnetic sticker, then align and mount the assembly on the back of your phone. No power supply, no cables, and no noisy fans required.

The patch measures 6.5 × 9.5 cm and weighs only around 50 grams. It features a durable TPU outer layer encapsulating high-performance phase change material (PCM). We offer phase transition temperature options of 18°C and 28°C, and custom temperature tuning is available to fit your unique application requirements.

The PCM absorbs excess heat from your phone steadily once it reaches its melting point, effectively reducing device temperature and preventing thermal throttling. Fully reusable after natural cooling. Compact and portable, it is an excellent accessory for mobile gamers, content creators, field workers, and anyone operating phones under high-temperature conditions.
