On the trail, at the job site, in the classroom, or simply sitting at home relaxing – the Celestron Elements ThermoTank 3 will keep your hands toasty warm with a maximum temperature of 113°F. Unlike single use chemical hand warmers, the ThermoTank’s lithium ion battery can be recharged and used again and again, saving you money over time.
ThermoTank 3 provides up to 4 hours of continuous heat on a full charge. The unit was thoughtfully designed with an ergonomic form factor to provide maximum contact with your hands. ThermoTank 3 provides scent-free heat that is undetectable to wildlife.
