It won't put any strain on your neck in any situation, and it's comfortable to wear without stiffening your shoulders, allowing you to enjoy a cool breeze anytime, anywhere. It won't put a burden on your neck even if you wear it all day. 【Same Core as New Energy Vehicles! Unbeatable Operating Time】 The neck cooler uses a 4000mAh core, the same type used in new energy vehicles, which significantly improves power efficiency.
