The rechargeable personal air conditioners They've carved out a niche among those looking to beat the heat without always relying on a split air conditioner or a traditional fan. In this context, Sony has decided to strengthen its position with a new version of its neckband device, designed to allow us to move around the street or be in the office with a bit more relief during a heatwave.
This new model, called Sony Reon Pocket Pro PlusIt has arrived in Europe and is now available in Spain. This device goes beyond the typical neck fan: it uses an active cooling system, is discreet under clothing, and has been redesigned to offer greater stability, better temperature control, and enough battery life to last a full day.
A mini air conditioner worn on the back of the neck

The Reon Pocket Pro Plus is not just a simple fan that moves air around your neck, but a personal air conditioner that works with the Peltier effectThis thermoelectric technology generates cold using electricity, cooling a metal plate that comes into direct contact with the skin and helps to lower the temperature at a key point in the circulatory system, at the back of the neck.
Its curved design is intended for to be worn discreetly under the shirt or any other garment, so that the user barely attracts attention. The base is placed on the back of the neck, where the refrigerated metal plate acts almost like a small ice pack that doesn't melt and is powered by a USB-C port for recharging.
Compared to previous models, this version incorporates two independent thermoelectric modules which operate alternately. This aims to maintain a more constant and stable cooling flow, preventing sudden temperature increases and decreases during continuous use, which is especially useful on long journeys or days at the office.
The device also includes a low noise internal fanIt is designed with a three-phase DC motor and fluid dynamic bearings. The idea is to keep the noise as contained as possible, so that it is not bothersome even in meeting rooms or quiet spaces.
More cooling power and intelligent thermal control
One of the main new features of the Reon Pocket Pro Plus is its improved cooling capacity. Sony indicates that the Cooling performance increases by more than 20% compared to the previous generation, which translates into an additional reduction in skin temperature of up to 2°C in smart operating mode.
To achieve this, the brand has developed a most advanced thermal algorithm It monitors both the device's own temperature and the ambient temperature. This system automatically adjusts the power to try to keep the surface close to 20°C, preventing excessive cooling that could be uncomfortable when worn for many consecutive hours.
In practice, this intelligent management system seeks a balance between a feeling of coolness and comfort. The device can operate in various environments. cooling levelsincluding a Smart Cool mode that modulates performance according to environmental conditions and data received from the external sensor, thus reducing unnecessary consumption peaks and noise.
The brand has even shown heat maps to illustrate how the Reon Pocket Pro Plus... dissipates heat in the neck areaThis takes advantage of the fact that it is an important point for regulating body temperature. Thus, a relatively small change in that area can translate into a greater feeling of relief than would be obtained simply by moving air around the face.
New adjustment system, more stability and less noise
Another aspect that has been improved in this version is the physical fit of the device. The Reon Pocket Pro Plus incorporates a New flexible band and fastening fins that rest on the neck and shoulders, improving stability compared to the previous model.
According to data provided by the company, the clamping force increases by about 40% compared to the previous generationThis should translate into fewer unwanted movements when we walk briskly, climb stairs, or make daily journeys on public transport.
The structure has been redesigned with a hinge capable of adapting to different neck sizes and body movements, seeking a more comfortable fit for different body types. In addition, the fin surrounding the ventilation area is now more flexible, which helps the device adapt better to clothing and head movements.
The air outlet system has also been modified, so that the Ventilation pieces allow for length and angle adjustmentThis makes it easier to use with high-necked garments or tighter shirts, improving heat dissipation even when the fabric covers a large part of the neck area.
Meanwhile, Sony claims that the Fan speed has been reduced Compared to the previous model, this does not negatively impact cooling capacity. This results in quieter operation, designed to avoid distractions or drawing attention in work or study environments.
Autonomy, usage modes and resistance
Despite this performance increase, the Reon Pocket Pro Plus maintains a Maximum autonomy of up to 10 hours at the second highest cooling level, according to figures provided by Sony. This margin is sufficient to cover a workday or a day of commuting, and can be combined with portable power stations if additional recharge is needed.
The battery is fully charged by USB-C connection and takes approximately 200 minutesIt can be recharged from a conventional charger, a laptop, or even a Extreme batteryThis can be useful during long trips or journeys where there are no available power outlets.
In addition to the cooling options, the device preserves a WARM heating mode with multiple levels for cold climates. This allows the device to be used also in winter or in environments where temperatures fluctuate greatly throughout the day, making it a usable accessory for much of the year.
In terms of durability, the Reon Pocket Pro Plus features protection against splashes of water and sweatIt is not a completely waterproof device, but it is designed to withstand everyday outdoor use, as long as it is not submerged or exposed to extreme conditions.
The unit also incorporates safety mechanisms during charging and automatic shutdown systems that act in case of overheating or abnormal situations, with the aim of protecting both the user and the electronic equipment itself.
Pocket Tag 2 environmental sensor and mobile app
The Reon Pocket Pro Plus comes with the new Reon Pocket Tag 2A small ambient sensor designed to work with Sony's personal air conditioner. This accessory measures the ambient temperature and humidity in real time to automatically adjust the cooling intensity.
The Pocket Tag 2 is more compact than its predecessor and It can be attached with a strap on the outside of clothing or in backpacks and bags, thus improving the accuracy of the measurements. Because it is exposed to ambient air, the data it collects is more representative of the actual conditions surrounding the user.
With this information, the system can to more precisely adjust cooling performancewithout the user needing to constantly change the operating mode. The goal is to offer a more stable feeling of comfort, both outdoors and indoors with variable air conditioning.
For those who prefer more direct control, Sony offers a app for iOS and Android From this interface, you can configure manual modes, usage profiles, cooling and heating intensities, as well as check the device's status. However, many basic functions are controlled directly from the device itself, so it's not necessary to keep it permanently connected to your mobile phone.
The ecosystem is designed to be compatible with smartphones with iOS 16 or later and Android 9 or higherThis covers most current phones on the European market. The connection to the mobile device also allows for firmware updates and the receipt of any software improvements over time.
