45K4219 - Rechargeable Hand Warmer
If you've ever found yourself clutching a hot cup of coffee just to keep your fingers warm in the cold, you'll understand why we like this convenient (but non-caffeinated) alternative. We prefer it over other hand warmers for several reasons. It's rechargeable, so you can use it over and over again without having to dispose of spent batteries or single-use chemical packets.
The slim, compact unit slips easily into a glove or pocket, where it warms to about 104°F (40°C) in less than two minutes and provides hours of warmth, regulated by an internal thermostat so it won't waste power or become uncomfortably hot. The internal lithium-ion cell (1000mAh capacity) charges in less than 2 1/2 hours from any standard USB port (charging cable supplied).
Whether for backcountry ski adventures or just sitting in a chilly arena during your child's hockey practice, it makes a great gift for anyone who works or plays outdoors during winter months.
