Beat the heat: This tiny gadget worn around your neck works like a personal air conditioner

India is experiencing one of its hottest summers, with temperatures frequently breaching the 45°C mark. People have turned to new ways to stay cool on the move, with portable fans becoming one of the season's most-used devices.

A potential alternative has emerged that could replace traditional portable fans entirely — Sony's REON Pocket series, a wearable gadget that acts like a personal air conditioner, cooling the body directly through skin contact.

Unlike portable fans, the REON Pocket relies on thermoelectric cooling technology. It sits on the neck under clothing and cools a metal plate against the skin — and can be used in both summer and winter seasons.

The device includes skin temperature sensors that monitor the wearer's neck temperature, while also measuring ambient air temperature — automatically adjusting cooling or heating based on humidity and user activity.

What makes the REON Pocket special is that it's hands-free and stays hidden beneath clothing, making it ideal for commuters and professionals — unlike portable fans, which are typically hand-held or visibly worn around the neck.

The Sony REON Pocket offers a glimpse into the future of wearable cooling tech, introducing an entirely new segment. However, the device is not currently available in India.

Its introduction in India could appeal to buyers amid rising temperatures and frequent heatwaves, potentially serving as a real alternative to portable fans for office-goers and outdoor workers — if priced right.
