SonyREON Pocket 5 Wearable Thermal Device RNPK-5T/W E

The most powerful cooling system in the REON POCKET series.

The REON POCKET 5 boasts up to 1.5 times more heat absorption*1 and significantly improved cooling performance when compared with the previous model in the series. It runs for approximately 4 hours at COOL Level 5 (the maximum cooling level) and for approximately 7.5 hours at COOL Level 4, which is around 1.8 times*2 longer than the previous model.
*1 Average amount of heat absorption when compared to the previous model RNP-4 while running with a charged battery at the maximum cooling level for 60 minutes. This may vary depending on usage conditions and environment.
*2 When compared to the battery life of the previous model RNP-4 while running with a rechargeable battery at COOL Level 4. This may vary depending on usage conditions and environment.

Quiet-yet-powerful cooling

Equipped with a newly designed thermal module and cooling fan. Operating noise is reduced by up to approximately 80%. The internal structure of the thermal module in the REON POCKET 5 has been redesigned and made larger, achieving up to 1.8 times the cooling efficiency.*1 This greatly increased efficiency results in more powerful cooling and longer running time. The cooling fan blade shape is optimised for the internal structure of the main unit, and the DC three-phase motor fluid dynamic bearing structure reduces operating noise from the device by up to approximately 80%.*2 This significantly lower noise makes the device even more suitable for use in a business environment.
*1 Average amount of heat absorption in relation to input voltage while running for 60 minutes when compared to the previous model RNP-4. This may vary depending on usage conditions and environment.
*2 When comparing noise level at COOL Level 4 against the existing model RNP-4 based on an internal measurement method. This may vary depending on usage conditions and environment.

Two air vent covers to match your style

Heat from the main unit is discharged behind your neck, keeping you cool.


For casual clothing, wear the short size. This shape avoids standing out when worn with a short collar and fully expels heat behind you.


For business clothing, wear the long size. This shape extends above the collar while matching the curve of your neck and back, expelling heat efficiently without standing out when worn with business clothing.

Neckband for an improved fit

The included dedicated neckband can be adjusted to suit neck size and angle. The REON POCKET's cooling/warming section stays in close contact with your body and provides stability that prevents the device from shifting when you move around. Suitable for a wide range of neck sizes from 34 cm to 46 cm. *A dedicated smaller-sized Neckband 4 (SMALL) (RNPB-N4S) is also available, sold separately.

The REON POCKET 5 can also be used in winter

The REON POCKET 5 can be used for both cooling and warming, with four adjustable WARM MODE levels to suit your preference.
In addition, when using SMART COOL⇔WARM MODE,* which automatically switches between COOL and WARM modes, the the device automatically adjusts itself to suit changes in the environment, even during volatile seasons with extreme temperature changes or days that have a mixture of hot and cold temperatures.
*Requires connecting the REON POCKET TAG with the REON POCKET.
