Celestron Elements ThermoTank 3 Hand Warmer

Keep your hands toasty warm whether you're on a hike, at the job site, in the classroom, or simply relaxing at home with the 113ºF maximum temperature provided by the Celestron Elements ThermoTank 3 Hand Warmer. Contrary to single use chemical hand warmers, the ThermoTank features a lithium-ion battery that allows it to be recharged over and over again for significant savings over time.

On a full charge, the ThermoTank 3 supplies up to 4 hours of continuous heat. It has been thoughtfully designed with an ergonomic form factor to provide maximum contact with your hands. In addition, the ThermoTank 3 provides scent-free heat that is undetectable to wildlife.
