The Reon Pocket is a wearable device which is kept in a pouch in a special t-shirt. The stealthy device doesn’t condition the air as such. Rather, it sits at the base of your neck and uses the Peltier effect (where heat is absorbed or emitted when you pass an electrical current across a junction) to either lower your temperature by 23F or raise it by 14F, all without bulk or noise.
The temperature can be controlled through a mobile app and can be set to the automatic mode. The battery can last for just 2 hours on a single charge which is quite disappointing. The device can be charged via a USB-C port which we expect to deliver fast charge.
Sony is also shipping the special t-shirt “RNPS-C1VA” comes in three sizes, S/M/L. You can choose white or beige as the colour and the price is 1,800 yen (~$16). The Reon Pocket is designed to fit around the neck.
