A portable personal air conditioner? That’s what Reon Pocket pretends to be, which is roughly the size of a smartphone and looks like an Apple Magic Mouse, it can cool your body down to 5 ° C on sweltering days.
In addition, it can also warm you during the winter, reaching a maximum of an additional 10 ° C.
To use the device, you have to slide the cooling unit into a special inside pocket on a T-shirt, which is located right between the shoulder blades . Sony is selling the custom-designed t-shirts to go with the Reon Pocket for about $ 20, but presumably, you could sew one onto your own t-shirts on the device, for a few bucks.
Once you have fitted your clothes with the cooling device just below your neck, you have to download the free Reon Pocket app on Google Play or the App Store for iOS devices. From there, you can toggle between cooling and heating and adjust the temperature with a single tap .
The Reon Pocket device should make contact with your skin (through your shirt) to cool you down. It uses the Peltier effect , a concept in thermodynamics, to cool down, unlike those little fogging gadgets you can see parents using at Disney World to cool down their kids.
The built-in lithium-ion battery lasts approximately two to four hours, depending on the configuration you use, and it takes approximately 2.5 hours to recharge the battery with a USB-C style port.
Although sales of the device began on July 1, it does not seem easy to acquire one outside of Japan. Reon Pocket is listed on Amazon’s Japanese site for $ 172 . It is unclear when the Reon Pocket will be made available to buyers around the world.
