Rechargeable heater, due to its built-in rechargeable battery and compact design, users can easily carry the heater wherever they need it. Not only can it be used outdoors, but it can also be used in indoor environments such as offices, bedrooms, etc., providing warmth for the cold season. Modern rechargeable heaters typically have safety features such as overheat protection and tipping off to ensure the safety of users during use.

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.
