Zippo Silver HeatBank 6 Rechargeable Hand Warmer

The Zippo HeatBank 6 is a silver rechargeable hand warmer giving up to six hours of warmth, doubling as a power bank.

Six hours covers a morning in a hunting blind, a day at a game or a walk in cold weather, which is the point at which a rechargeable warmer beats disposable air-activated packs. Disposable warmers cannot be turned off once opened, so a partly used one is wasted. This one switches off and goes back in a pocket.

Doubling as a power bank means it charges a phone as well as warming hands, so it stays useful on days when the weather turns out mild. Silver is the brighter of the two finishes, easier to find in a bag than the black version. Explore more survival gear.
