A household heater is an electrical device that converts electrical energy into thermal energy for indoor or object heating. They are widely used in winter heating, heating water, drying clothes, and other fields. Electric heater is the most common type of heater, which heats indoor air through heating wires to achieve the purpose of heating up. But electric heaters have a high power output, so safety precautions should be taken when using them.

Specifically, when a charging heater is charged, its internal heating element begins to generate heat and transfers it to the external container of the heater, causing the liquid inside the container (such as water) to heat up. Due to its portability, rechargeable heaters have a wide range of applications in various fields such as home, office, industry, and agriculture.

A rechargeable heater is an electric heating device characterized by a built-in rechargeable battery that can be charged through a USB charging cable or other charging methods. Its working principle is similar to traditional electric kettles or electric heaters, both of which use electrical energy to generate heat energy. However, the difference is that rechargeable heaters do not require a continuous external power supply, making them particularly practical outdoors or in environments without a stable power supply.

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.
