【Operation Confirmed, Unused】2026 Latest Peltier Cooling Vest with Large Capacity Battery

Thank you for viewing.

This is the latest 2026 model Peltier element cooling vest (cool vest).
It comes as an all-in-one set with a 30,000mAh high-capacity mobile battery, so you can use it right out of the box.

This is an **unused item** that has only been powered on and tested for cooling function. We have confirmed there are no initial defects, so you can use it with confidence.

Unlike air-conditioned clothing (wearable fans), this vest does not inflate your clothing, so it won't get in the way of your work. It fits neatly under motorcycle riding jackets, as an inner layer for outdoor activities, or for use in kitchens.

[Product Features]
- Instant Cooling: The back plate cools down in about 10 seconds after powering on, reducing perceived temperature by up to -25°C.
- 30,000mAh High-Capacity Battery Included: Can operate for approximately 4-5 hours on strong mode and 6-7 hours on weak mode.
- Quiet Operation: Features a reliable Japanese-made DC motor with a very quiet operating noise of 31dB.
- Free Size (Equivalent to S-5L): Unisex, with adjustable side cords for a snug fit.
- Excellent Breathability: The back and shoulder areas are made of mesh fabric for comfort even when sweating.
