Sony’s Reon Pocket Wearable Air Conditioner

On Sony’s crowdfunding platform in Japan, the slender, personal thermoelectric cooling unit known as the Reon Pocket can purportedly reduce a user’s body temperature by 13 degrees Celsius (or 23 degrees Fahrenheit). About the size of a card wallet, the Bluetooth-equipped device slips into a dedicated sleeve on the back of an accompanying undershirt. Its temperature can then be controlled through an iOS or Android app. It’s light and lasts about 24 hours per charge (via USB Type-C). And during the winter, it can be used as a heater. While funding now (for approximately $117), Sony plans to have the item ready by March 2020. Read more at The Verge.
