Sony REON POCKET PRO Plus (RNPK-P1PT)

Commuting, Office Wear, Summer Heat Relief, Winter Warmth, Outdoor Work, Travel

Overview

The Sony REON POCKET PRO Plus (RNPK-P1PT) is the 2026 flagship of Sony Thermo Technology's wearable thermo line, worn inside the collar to cool or warm the skin directly at the back of the neck through two alternating Peltier modules rather than blowing air at your face. It lifts maximum cooling output about 20% over the previous REON POCKET PRO and runs a new app-driven algorithm that holds the contact plate near 20°C, paired with a grab-happier Adaptive Hold neckband and an adjustable airflow part for discreet heat exhaust under any collar. A 3,000mAh battery delivers up to 15 hours in SMART COOL mode and 34 hours at the lowest cooling level, recharging to 80% in about two hours over USB-C, and the sensing kit bundles REON POCKET TAG 2 for automatic COOL-to-WARM switching as the weather changes.

Key Highlights

  • 20% more cooling output than the REON POCKET PRO and a cooling surface up to 2°C colder, with a new SMART COOL algorithm that holds the plate at a comfortable 20°C instead of over-chilling the skin
  • DUAL thermo modules plus a vapor chamber, low-RPM fluid-bearing fan and precision fins keep the flagship cool continuously and quietly enough for meetings and offices
  • Adaptive Hold Design neckband PRO Plus grips about 40% more firmly than the previous band while staying flexible, and the adjustable airflow part can be angled to match any collar
  • Up to 15 hours in SMART COOL mode (34 hours at COOL level 1) from a 3,000mAh battery, recharging to 80% in about 120 minutes over USB-C with play-while-charging support
  • Year-round use with SMART WARM and automatic COOL to WARM switching via the bundled REON POCKET TAG 2, plus AUTO START/STOP wear detection and Bluetooth 5.0 app control

Technical Specifications

Brand Sony (Sony Thermo Technology)
Model Sony REON POCKET PRO Plus (RNPK-P1PT)
Thermo Technology Wearable thermoelectric (Peltier) thermo device: DUAL thermo modules (two independent Peltier modules driven alternately at varying intensity) cool or warm the skin directly at the nape, backed by a vapor chamber, a large low-RPM heat-dissipation fan and precision-machined fins — no cold-air blast at the face
Cooling Performance Maximum cooling output up to ~20% higher than the previous flagship REON POCKET PRO (RNP-P1); cooling-surface temperature up to 2°C lower, verified at 35°C ambient after 10 minutes; new SMART COOL algorithm targets a 20°C cooling-surface temperature to avoid over-cooling; manual COOL levels 1-5
Heating Performance Manual WARM levels 1-4 with more powerful warmth than earlier models thanks to the DUAL thermo modules; usable year-round for winter wear
Smart Modes SMART COOL (auto-adjusts level from built-in sensors, activity and app-set preference), SMART WARM, SMART COOL⇔WARM auto-switching (requires REON POCKET TAG 2), Manual mode (COOL 1-5 / WARM 1-4), AUTO START/STOP wear detection that powers on when worn and off when removed, USB-powered operation while charging
Battery Life COOL: approx. 34h (L1) / 27h (L2) / 18h (L3) / 10h (L4) / 5.5h (L5); WARM: approx. 10h (L1) / 8h (L2) / 6.5h (L3) / 5.5h (L4); SMART COOL mode: up to 15h (30°C room, initial settings); continuous use auto-pauses after 15h COOL or 8h WARM
Charge Time Approx. 120 min to 80%, approx. 200 min to full charge
Charging Port USB Type-C (L-shaped USB-C to USB-C cable included; USB AC adapter not included)
Connectivity Bluetooth 5.0 Low Energy
App / OS REON POCKET app (Ver. 2.2.0 or later required for the 20°C algorithm and strong-cool mode): iOS 16 or later / Android 9 or later
Water Resistance Drip-proof and dust-proof construction with sealing on the cooling/warming surface, internal parts, buttons and the USB port cover (not waterproof — do not use in rain or snow)
Contact Surface Stainless steel SUS316L
Operating Temperature 5°C to 40°C (avoid temperatures above 35°C or prolonged direct sunlight)
Neckband Neckband PRO Plus (RNPB-NP1P) with Adaptive Hold Design: larger-diameter mechanical flexible tube for ~40% more holding force while staying flexible, soft band supporters, and an adjustable airflow part whose length and angle can be set to match collar height; a short airflow part is also included
Weight Approx. 259g (8.7-9.1 oz) with neckband PRO Plus + short airflow part; approx. 270g with adjustable airflow part; approx. 194g main unit only
Dimensions With neckband PRO Plus + short airflow part: approx. 125 x 60 x 175 mm; with adjustable airflow part: approx. 125 x 60 x 210 mm; main unit (RNP-P1) only: approx. 58 x 36 x 134 mm
Price $259.99 (US, RNPK-P1PT sensing kit with REON POCKET TAG 2); Japan: ¥27,500 for RNPK-P1P standalone, ¥29,700 for RNPK-P1PT sensing kit (tax incl.)
