Zippo HeatBank 6 Features The Zippo HeatBank 6 heats on both sides of the unit surrounding the hands with warmth rather than heating just one surface. Three selectable heat settings let the user choose the right balance between battery life and warmth scaling up to a 120 degree Fahrenheit maximum operating temperature. Battery and heat indicator lights give a quick visual check on remaining charge and the active setting without needing to guess. Backed by a rechargeable 4 400 mAh lithium-ion battery the unit delivers up to six hours of continuous run time on a full charge. Beyond hand-warming duty the HeatBank 6 doubles as a USB power source capable of charging phones tablets cameras and other USB-compatible devices in the field. This dual function means one device covers both personal warmth and backup power on a hunt hike or extended outdoor outing. Recharging is handled through the unit s own charging process keeping the HeatBank ready for repeated use across a season. For hunters outdoorsmen and anyone who spends extended time in cold conditions the Zippo HeatBank 6 offers a reliable combination of warmth and portable power.
