Celestron Elements ThermoCharge 3 is a must-have 2-in-1 tool that everyone needs: a long-lasting hand warmer that provides up to 4 hours of continuous heat and a portable power bank to charge your personal electronics.

Whether you’re enjoying a cold hike, camping, stargazing, or just sitting on your front porch, the ThermoCharge 3 will provide heat and power to keep you going. It’s a great addition to your adventure gear or emergency kit.

ThermoCharge 3 will keep your hands toasty warm with a maximum temperature of 113°F. It features an ergonomic design to provide maximum contact with your hands, keeping you warm and comfortable. Unlike single-use chemical hand warmers, ThermoCharge is scent-free and its lithium ion battery can be recharged again and again.

When you need to top off the charge on your smartphone or tablet, just plug it into the 5V-1A charging port. You can even use the charging and hand warmer functions at the same time.
