Sony is crowdfunding a wearable air conditioner called the Reon Pocket which is supposed to help you cope with both hot and cold weather.
The device slips into a pocket on a specially designed t-shirt and doesn’t “condition” the air. Instead, it sits on the back of your neck and uses science which includes the use of heat that is absorbed or emitted when an electric current passes through a junction. The device is said to help regulate your body temperature between 32 and 42 degrees Celsius. You could wear a stuffy business suit on a hot day and NOT look like you just had a sauna.
The device is connected to a mobile application which helps you regulate the temperature. However, Sony hopes to automate this feature soon. Actual battery life is less than 2 hours, so it won’t work for a full day but rather those moments that you are feeling hot under the collar. Charging time is also expected to be at 2 hours.
Unfortunately, the Reon Pocket is not available but it’s pretty close to full crowdfunding. It’s expected to ship by March 2020 and only for the Japanese market (so far). The price for the device in the South African market will probably be between R2000 and R3000 rand, which is a pretty penny when you could just buy a fan.
