When I saw that product first time, I fell in love with it!
Reon Pocket works on tiny and wearable air conditioning devices. Actually that startup from Sony’s startup acceleration program.
This lovely device utilizes thermoelectric cooling but Sony says you can also use it as a heater on winter days. It can supposedly cool a user’s body temperature by 13 degrees celsius.
Wearable AC works with Bluetooth technology and you can manage it from your iOS or Android device. Wearable air conditioner has a battery life of 90 minutes and a charge time of it about to 2 hours. This device almost same size with Apple Magic Mouse or Credit Card. Weighs just 85 grams and using USB-C port.
