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.
