It provides gentle warmth when temperatures dip and features a USB port to charge up smartphones and tablets, so that users can stay connected while on the hill or campsite. Providing up to six hours of continuous heat at the push of a button, the portable hand warmer offers five settings from low to high and heats up to 50 degrees Centigrade (when the internal power bank is charging a mobile device, the heat functions are disabled to prevent overheating).
