Sony REON POCKET 4 Wearable Neck Cooler/Heating Device with Automatic Cooling, Warm/Cold Function, Lightweight, and Compatible with Mobile Battery

What is REON POCKET? REON POCKET is a wearable thermo-device that can directly cool or warm the skin surface where it comes into contact with the device. It can be used in both summer and winter, as it is compatible with both cooling and heating. *REON POCKET is not intended to prevent heatstroke. Please refrain from using it for long periods of time in temperatures above 35°C or in the hot sun, or during work or exercise that involves heavy sweating.

Increased battery capacity provides approximately double the operating time. Increased battery capacity provides approximately double the operating time (*1). It can be used for approximately 7 hours even at COOL level 3. The battery has been strengthened and the design has been revamped, maintaining a more powerful yet compact body. The air intake has been redesigned to allow for more efficient air circulation. Furthermore, the heat dissipation mechanism has been enlarged, achieving approximately 1.2 times (*2) the heat absorption performance. *1 When comparing operating time with the previous model RNP-3. Actual operating time may vary depending on usage and environment. *2 When comparing the maximum cooling level heat absorption performance (average heat absorption amount after 60 minutes of operation) with the previous model RNP-3. Results may vary depending on usage and environment.

Five sensors detect temperature, humidity, and activity. In addition to the newly installed temperature and humidity sensor, three temperature sensors detect temperature and humidity. Additionally, an accelerometer detects activity. Based on the information detected by these sensors, smart functions are provided to suit the situation.

SMART COOL MODE automatically adjusts the cooling temperature based on activity, the environment, and personal preferences set in advance in the app. The newly installed temperature and humidity sensor can now detect increased humidity due to sweat, further improving SMART COOL MODE. Furthermore, by connecting with the separately sold REON POCKET TAG (RNPT-1) (*1), a new function, SMART COOL⇔WARM MODE, automatically switches between COOL and WARM modes, is now available. (*2) This function automatically adjusts to changing environments, not just in summer, but also during seasonal changes when cold and hot temperatures alternate throughout the day. *1 The REON POCKET TAG (RNPT-1) can be purchased with the REON POCKET 4 Sensing Kit (RNPK-4T) or separately. It is not included with this product (RNPK-4). *2 The RNP-4 alone only supports SMART COOL MODE (cooling). Neckband for a Perfect Fit3 The included dedicated neckband can be adjusted to fit the size and angle of your neck. The cooling/heating surface of the REON POCKET adheres firmly to the device, preventing it from slipping even when moving, providing a stable fit. It fits a wide range of neck sizes, from 34cm to 46cm. The newly designed band is designed to provide both flexible adjustment and firm hold in place. The adjustable mechanical flexible tube, the wire frame that maintains its shape, and the silicone rubber covering them provide a gentle feel against the skin, even when worn for long periods of time. Even when wearing clothing with a collar, using the included airflow parts promotes heat dissipation and reduces the risk of air exhaust.
