【New】-13℃ Peltier Neck Cooler with 30000mAh Battery - Expires 2026

The Amazon product page states: Peltier semiconductor cooling technology - cools up to -17°C.

I was issued this by my company because the air conditioning fan is noisy during commutes and business trips. However, I commute by car and have been transferred to an office-based role, so I am selling it unused, having never used it once.

My colleagues who work outdoors during the day say that with this, they stay cool even when wearing a suit and their sweat dries up.

This is the latest model currently being sold by the manufacturer on Amazon.
Here is the description from Amazon:
