The working principle of a rechargeable heater is mainly to convert electrical energy into thermal energy through internal electric heating elements, and then use a fan to blow out the heated air, thereby achieving the goal of increasing the ambient temperature. Usually, this type of heater has multiple setting options, such as different temperature levels, wind direction adjustment, etc., to meet the needs of users in different scenarios.
