How do flameless hand warmers work?

The concept behind the Zippo Hand Warmer is that through the combustion (ignition) of zippo fluid (light petroleum distillate) it becomes a catalytic heater, relying on a catalyzed chemical reaction to break down molecules and create heat.

How does a battery hand warmer work?

In them, a rechargeable battery sends power to an onboard electrically resistive heating device, which converts that energy into heat. On simple devices, the level of heat is fixed. On more complex ones, the user can select the level of heat put out by the device.
