The protective case for mobile phones is formed by stamping with grinding tools. Mobile phone cases are mostly made of plastic: they can be divided into materials such as ABS, PA nylon, PA12, ABS+PC alloy, PA66, PVC, TPU, HDPE, PC polycarbonate, and PP polycarbonate (polycarbonate)

Generally, it is necessary to first select the appropriate charger type, protection type, output voltage, and current specifications based on the type and voltage of the rechargeable battery, and then according to the grid voltage. Select a charger that meets the corresponding input conditions. It is best to choose a fully intelligent battery charger.

1、 What do the nominal voltage and current of a power adapter (hereinafter referred to as a power supply) mean? Firstly, the nominal voltage of a general power supply refers to the open circuit output voltage, which is the voltage when there is no external load and no current output. Therefore, it can also be understood that this voltage is the upper limit of the power supply output voltage.
