Sony’s Wearable Air Conditioner Reon Pocket Arrives in the US

As summer temperatures continue to climb across the globe, tech giant Sony is introducing a unique solution to the US market: the Reon Pocket. Originally launched as a crowdfunded project in Japan, this wearable device functions as a personal air conditioner or heater, sitting discreetly at the base of your neck. After finding success in Asian markets, the compact gadget is finally making its way to American consumers, promising a new level of thermal comfort for commuters, office workers, and outdoor enthusiasts.

The device, which resembles a sleek, slim smartphone battery pack, is designed to be worn inside a specially engineered undershirt. It tucks into a pocket located right between the shoulder blades, where it uses the Peltier effect—a thermoelectric process that creates a heat flux—to either cool or warm the surface of the skin. By targeting the base of the neck, where blood vessels are close to the surface, the Reon Pocket claims to help regulate the wearer's perceived body temperature effectively.

During initial hands-on testing, the device proves to be surprisingly subtle. Once paired with the smartphone app via Bluetooth, users can toggle between cooling and heating modes, or select an 'auto' mode that uses internal sensors to adjust the temperature based on the wearer's activity level and the ambient environment. In cooling mode, the device can provide a noticeable sensation of relief, which is particularly useful for those struggling with the humidity of a summer commute. The transition between modes is near-instant, allowing for quick adjustments as you move from a sweltering outdoor sidewalk into an air-conditioned office building.

However, the Reon Pocket is not a substitute for traditional air conditioning. It is designed to change the perception of temperature rather than physically cooling the air around the entire body. Its efficacy depends significantly on proper contact with the skin and the use of the proprietary shirts designed to hold the unit in place. Without these garments, the device cannot function as intended, which may be a point of friction for some users who prefer their own wardrobe staples.

Battery life remains a central focus for prospective buyers. Depending on the intensity settings chosen in the app, the device typically offers a few hours of use before needing a recharge via USB-C. For those with long commutes or extended periods spent outdoors, the need for a power bank or frequent charging might limit its convenience. Despite this, the tech represents a significant leap in 'wearable climate control,' a niche category that has struggled to gain mainstream traction in the past.

As Sony prepares for the US rollout, the company is positioning the device as a lifestyle accessory for tech-savvy individuals. While the pricing and specific launch date for the North American market are still being finalized, the expansion suggests that Sony believes there is a significant appetite for personal climate control technology. Whether it becomes a must-have summer gadget remains to be seen, but the Reon Pocket is undeniably one of the most interesting pieces of hardware currently coming out of Sony’s innovation labs.
