Why can warmer produce heat and keep so long time?

       

Warmer, hand warmer and foot warmers are through the slow oxidation of iron powder exothermic, again through the galvanic battery principle of accelerated oxidation, which changes the chemical energy into electrical energy, and then it uses vermiculite to keep temperature, so it can be used for 12 hours, the temperature of whole process basically keeps constant.
