About this item

[Total 14000mah provides Up to continuous 42 Hours of Warmth] Each 2000mAh hand warmer lasts 3 to 6 hours depending on the heat setting. The 10,000mAh charging case provides 2.5 full charges for both hand warmers, adding 7.5 to 15 hours of extra warmth. Combined, you can enjoy 10.5 to 21 hours of heating with both units, or up to an incredible 42 hours of uninterrupted warmth with just one hand warmer, perfect for extended outdoor adventures.
[Intuitive One-Press Control for Easy Operation] Our hand warmers feature an intuitive one-press control for seamless operation. A short press allows you to cycle through three temperature settings—95℉ - 108℉, 109℉ - 119℉, and 120℉ - 131℉—while a long press conveniently switches the device on or off. This simple design ensures you can quickly find your preferred warmth and power the hand warmers without taking out your hands out of the gloves or pocket, perfect for any cold weather situation.
[AI Temperature Sensor Chip provides precise heat and safe] Our hand warmers utilize an advanced AI temperature sensor chip to provide precise 3-level heat regulation with wave-like delivery for consistent warmth. For added safety, both the charging case and hand warmers feature a smart chip that automatically cuts off power if temperatures exceed safe levels. With UL, CE, and FCC safety certifications, you can trust in the safe and reliable performance of our hand warmers.
[Dual-Sided Heating & Ergonomic Design for Enhanced Comfort] Each hand warmer is equipped with dual-sided heating, ensuring both hands receive consistent warmth. The ergonomic curved design is smooth and rounded, fitting perfectly in your palm and allowing for even heat distribution. This thoughtful design maximizes every bit of warmth, providing you with a cozy experience whether you're outdoors or relaxing at home.
[Compact, Lightweight, and Portable for All-Day Carrying] Compact enough to fit in your pocket or bag, these lightweight hand warmers are easy to carry wherever you go. The sleek design fits comfortably in your hands, making them a perfect solution for hikers, skiers, and anyone needing extra warmth on cold days.
