Portable hand warming stick

The invention discloses a portable hand warming stick. The portable hand warming stick is composed of an alcohol-based fuel tank and a catalyst tank located on the alcohol-based fuel tank. A catalystis placed in the catalyst tank. A component for fixing the catalyst and allowing gas to pass through is arranged between the catalyst tank and the alcohol-based fuel tank. The top and the upper half portion of the outer wall of the catalyst tank are provided with a plurality of air inlets/outlets. The alcohol-based fuel tank contains limestone. The limestone adsorbs alcohol-based fuel. According to the portable hand warming stick, under the action of the catalyst, the alcohol-based fuel and the air have a catalytic combustion reaction to release a great deal of heat to heat the hand warming stick under the conditions that no open fire is generated and the hand warming stick is not recharged. The portable hand warming stick has the advantages of being friendly to environment, high in efficiency and capable of being
