Today's electronic products are constantly updated and developed, bringing people a lot of convenience. Mobile power is one of them, and it has also been recognized by many consumers. So, is it normal to heat up when the mobile power supply is charging? What causes the heat? The following will answer for you with the editor.

1. The mobile power supply generates heat because during use, part of the battery energy cannot be 100% output, and a part of it will be consumed in the internal circuit of the mobile power supply in the form of heat. The higher the efficiency, the heat will be generated. The lower is because the less energy is lost to the circuit. Of course, heat will also bring some serious problems, such as: overheating and short-circuit burning, high temperature accelerates the aging of components.

2. The structure of the mobile power supply for mobile phones: the structure of the mobile power supply for smart and safe mobile phones: battery core + protection board + shell + additional functions.

3. The classification of mobile power: there are iPhone backup mobile power, external mobile power, leather case mobile power, universal mobile power, protective shell mobile power and so on. According to the different electrolyte materials used in lithium-ion batteries, lithium-ion batteries can be divided into two categories: liquid lithium-ion batteries (Li-ionBattery) and polymer lithium-ion batteries (PolymerLithium-ionBattery, referred to as Polymer).

4. Because of the structure problem of the mobile power supply, there are also the problem of the circuit board and the material. Caused his fever.
