The MEMO CX21 mobile semiconductor cooler is designed for anyone whose phone overheats during extended gaming, streaming, or video recording sessions. The cooler utilises a Peltier element with a cooling power of 18 W, which actively dissipates heat from the back of the phone. This allows the phone to maintain a lower temperature even during demanding games, preventing a significant drop in processor performance. The cooler attaches to the phone via a magnet or a rear clip, making it compatible with a wide range of smartphones. It is powered through a USB-C port with a nominal input of 9 V/2 A.
The heart of the cooler is a large TEC cooling plate measuring 30 x 30 mm, with an area of 900 mm², which evenly cools the surface on which the cooler rests. Heat from the top of the plate is dissipated by an aluminium heatsink with large pass-through fins and a quiet fan with seven blades. Air flows vertically up and down, ensuring that warm air does not blow into your hands, keeping the phone comfortable to hold. The cooler has compact dimensions of 63 x 60 x 30 mm and occupies approximately one-third of the back of a standard phone, so it does not obstruct your fingers when gaming in landscape mode.

Phones with MagSafe compatibility attach directly to the cooler thanks to the strong neodymium magnet. For other phones or cases, you can stick the included magnetic plate to the back, or use the rear spring clip, which securely grips the phone from the sides. To achieve the lowest temperature, the manufacturer recommends powering the cooler with a 9 V/2 A output adapter, which is not included in the package. Keep the cooling surface and ventilation openings clean and dust-free to ensure air can flow freely and the cooler operates as efficiently as possible.
The MEMO CX21 is a practical accessory for mobile gamers, streamers, and content creators who need their phone to handle prolonged use. The combination of semiconductor cooling and a fan effectively reduces the temperature of the back of the phone during gaming and recording. The versatile attachment via magnet or clip allows the cooler to be used with many types of phones and enables quick installation or removal. The LED backlighting gives your gaming setup a striking appearance, and the compact body easily fits into a pocket or backpack.
