About this item
• AI Chip Anticipates Changes: A millisecond AI chip reads the ambient temperature and how fast it’s changing, then adjusts power before you feel the swing. Holds your set temp within ±2–4°F for steady, all-day comfort.
• 3 Heat Levels, All-Day Ready: Set to 104°F, 111°F, or 120°F. Battery lasts about 3-8 hours per charge (varies by level and ambient temperature). Ideal for nighttime warmth, outdoor work, winter walking, and hunting; helpful for cold-sensitive hands (e.g., Raynaud’s).
• Ultra-Slim & Magnetic: Pocket-friendly at 0.6". Magnetically attach two warmers for instant double-sided heat, or wear gloves and slip one warmer in each glove for even greater warmth. You can also keep one in a coat or pants pocket to enjoy a warm pocket whenever you need it.
• Certified Safe: Tested to UL/FCC/CE with multi-layer protections (overheat, short-circuit) for reliable indoor/outdoor use - at work, on the trail, or at the office.
• Gift-Ready & Versatile: Sleek feel and finish make it a great Christmas/winter gift for men, women, and kids. Perfect for outdoor activities - skiing, golf, camping, hiking, hunting, and everyday walking.
