Description

Technical field [0001] The invention relates to an electric hand warmer, in particular to a portable battery hand warmer. Background technique [0002] At present, there are many varieties of hand warmers in the market, including electric hot water bottles, hand warmers, electric heating cakes and so on. This kind of hand warmers are all heated by high voltage to reach a certain set temperature before heating. Due to the use of high voltage heating, the safety risk factor is large, and because of insulation, the thermal conductivity has many layers and the startup temperature rises slowly. The material is thick, the product is heavy, it is inconvenient to carry, it cannot be opened and used at any time, and it cannot be used during electric heating. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortcomings and shortcomings to provide a hand warmer that is portable and battery-heated, which is compact and lightweight, can be used...
