TORRAS PolarCircle Qi2 Mag-Safe Charger, 15W Cooling Magnetic Pad for iPhone 16/15/14/13, Wireless Charger for Samsung Galaxy S25 with 360Spin Stand, Semiconductor Game Cooler, with 5ft Type-C Cable

PolarCircle QI2 wireless magnetic charger combines cooling ice sensation, a 360 stand, and speedy charging, maintaining efficient performance in any gaming, movie watching, and meeting scenario. Say no to phone heating, battery degradation, snail charging, and the inconvenience of moving around. Semiconductor coolingTora-ice technology uses advanced TEC semiconductor cooling to maintain optimal charging temperatures. This magnetic charger for iPhone reduces charging temperature by 77 degrees Fahrenheit, preventing overheating and ensuring efficient charging. No need to worry about performance drops during gaming or movie watching. Protect the health of your battery while maintaining optimal performance. A 3-second press to switch the fan onoff is super easy. Qi2 Certified Fast ChargingOur phone charger supports Qi2 certification, delivering reliable 15W wireless fast charging. Unlike conventional chargers that may slow down due to heat, our cooling technology maintains double speed and peak performance throughout the charging cycle. Meanwhile the strong magnetic connection of 11N reduces the loss of wireless charging and improves efficient fast charging. Please use it with a plug of 30W or more.. Multi-functional 360 Rotating StandCooling Mag-safe Charger comes with a 360 rotating stand that easily meets the needs of any angle. Switch between horizontal and vertical while charging your phone, it is convenient to watch videos, play games and hold meetings. Break the barrier of the charging cable No more aiming at the charging port of your phone. Just a light touch and magnetism will help you do it all.
