Stay warm on the trail with the Celestron Elements Thermotrek Hand Warmer (Hunting Version). The 4400 mAh lithium ion battery provides up to an impressive 6 hours of continuous heat on a full charge. ThermoTrek heats up quickly and reaches a maximum temperature of 113 degrees Fahrenheit (45 degrees Celsius).
Unlike chemical hand warmers, ThermoTrek can be recharged multiple times. Just plug it into the USB port on your PC or a compatible AC charger using the included cable. The rugged aluminum construction and protective silicone caps make ThermoTrek perfect for cold weather excursions like cross-country skiing and mountaineering.
