REMAX RT-F12 AI Magnetic Phone and Tablet Cooler - Black

A magnetic cooler sized for phones and tablets. A semiconductor plate chills the back of the device, an NTC sensor tracks its temperature, and an LED display shows the reading live. It holds on with an N52 neodymium magnet, so it snaps onto a phone with magnetic charging, or a case fitted with a magnetic ring.

Three modes: P1 for standard cooling, P2 for large-area icing during games and streams, and an AI mode that sets the level for you. An RGB ring lights the front. It takes 9 V at 2 A through USB-C and is rated at 15 W; it measures 66 × 67 × 23 mm and weighs 85 g.
