Adapter Introduction

The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into an AC output type and a DC output type; And desktop. Mobile PCs are especially important because they don't have a battery.

Most mobile PC power adapters can automatically detect 100~240V AC (50/60Hz). Basically, all mobile PCs have external power supplies and are connected to the host computer by a single line. This reduces the size and weight of the mainframe. Only a very small number of models have built-in power supplies into the mainframe. There is a nameplate on the power adapter, which indicates the power, input and output voltage and current quantity. Pay special attention to the range of input voltage. This is called the "Travel Power Adapter".
