What Is the Reon Pocket Pro Plus and How Does It Work?
The Reon Pocket Pro Plus is Sony’s newest wearable air conditioner, a compact personal cooling device that sits at the back of your neck under your clothing. Unlike a simple fan, it uses a cooled metal plate based on the Peltier effect to draw heat away from your skin. That plate targets the neck, a spot where blood vessels run close to the surface, so temperature changes can feel quicker and more noticeable. A small fan and exhaust system then push hot air away from your body, helping to reduce sweat and discomfort in hot environments. Sony positions this as an evolution of its portable AC technology, first introduced in 2019, turning what began as a niche gadget into a more refined tool for everyday comfort during commutes, office work, or light activity, without relying on traditional room air conditioning.
20% Stronger Cooling and a Real-World 2-Degree Difference
Sony claims the Reon Pocket Pro Plus delivers 20% stronger cooling than its previous wearable AC models. In practice, that translates to the cooled plate reaching temperatures around 2 degrees Celsius lower than before. While that number may sound small, on the skin it can be the difference between feeling uncomfortably warm and genuinely refreshed, especially when heat is trapped under clothing or during a hot commute. The device also uses dual thermo-modules and an updated control algorithm that monitors both your skin and the surrounding air. With the companion app, you can set a target temperature and let the system automatically modulate output as conditions change. For people sensitive to heat or working in warm indoor spaces, a consistent 2-degree reduction right where blood flow is concentrated can help slow sweating and maintain a more stable body comfort level over time.
Redesigned Neckband and Adjustable Vents for All-Day Wear
The Reon Pocket Pro Plus doesn’t just cool better; it also aims to stay put more reliably. Sony has redesigned the neckband with flexible arms that grip your shoulders more securely, reducing wobble as you walk, bend, or turn. This makes it better suited for daily wear, such as commuting or light movement, though it’s still not meant for intense sports. The slimmer, more discreet profile is intended to disappear under light-colored shirts, especially in the new light gray finish. A key upgrade is the adjustable exhaust vent, which can be extended and angled so hot air is blown away from your body rather than trapped under high collars or jackets. Together, the improved fit and adjustable airflow make this wearable air conditioner more practical for real-world use, where comfort depends as much on stability and discretion as on raw cooling power.
Battery Life, Smart Controls, and Everyday Use Cases
Sony’s portable AC technology is backed by smarter controls and longer runtimes in the Reon Pocket Pro Plus. On cooling-focused modes, the device can run for up to 10 hours at higher settings, and up to 15 hours when using its adaptive smart cooling mode that dynamically adjusts output. You can control it via a companion app, setting target temperatures or switching between heating and cooling, but there are also physical buttons for quick adjustments without your phone. The wearable operates quietly, making it suitable for offices, classrooms, and public transport. It’s bundled with the Reon Pocket Tag 2, a small sensor that clips to your bag or belt to measure ambient temperature and humidity. That data feeds back to the main unit, letting it fine-tune cooling automatically. Together, these features position the Reon Pocket Pro Plus as a more complete personal cooling device rather than a simple gadget.
How the Pro Plus Compares to Earlier Reon Pocket Models
Compared to earlier Reon Pocket generations, the Pro Plus focuses on three clear upgrades: stronger cooling, better wearability, and smarter airflow. Previous models already used a cooled plate and fan, but the new version’s 20% performance boost and 2-degree Celsius improvement make the cooling feel more immediate on the neck. The neckband redesign directly addresses earlier complaints about fit, with a more stable grip that helps the device stay centered along the spine. The adjustable exhaust vent is also new, solving the issue of warm air building up under high collars or layered outfits. Sony has maintained its emphasis on discreteness, with a color and form factor that aim to blend under light clothing. By refining these fundamentals, the Reon Pocket Pro Plus turns the concept of a wearable air conditioner into something closer to an everyday personal cooling tool instead of a one-off tech curiosity.
