Heat from the package. Those who don't want to use a rechargeable battery but still want to have a source of additional heat on them at all times, should choose the hand warmer model.
When taken out of their airtight packaging, the carbon fibres in the hand heat packs combine with the oxygen in the air and heat up to about 50 degrees Celsius. When placed in the Snowlife heating bag these hand heat packs give off a pleasant amount of heat for about seven hours.
