Inferno Rechargeable Hand Warmer

This amazing little tool keeps your hands warm and toasty, while also giving you a long-lasting source of backup USB power. Small enough to fit any pocket, the Inferno is the perfect companion for any winter excursion. Just charge it up using the included USB cable, and  never worry about having cold hands or a dead phone while you’re out in the cold! Whether you’re hitting the ski slopes or simply doing chores on a January afternoon, the Inferno will keep your hands warm for 10-14 hours when set on Low (95 degrees) – perfect for a long day in the cold. But if you need more heat, it’s adjustable up to 120º and will give you around 8 hours on Medium and 6 hours on High. Even on the hottest setting, it lasts far longer than normal handwarmers, and also includes an auto-shutoff to prevent overheating.
