The Difference Between A Lithium Battery Charger And A Power Adapter

Before introducing the difference between the charger and the power adapter, let's meet what is called a charger and what is the power adapter.

Charger: English name charger, usually refers to a device that converts alternating current into low-voltage direct current, which includes the control circuit which satisfies the charging characteristic, such as limiting current and limiting pressure. Chargers are widely used in various fields, especially in the field of life, such as mobile phones, cameras and other common electrical appliances.

Power adapter: English name adapter, the market common power adapter is the power converter, rectification and voltage regulator, output is DC, in the case of power can be understood as low voltage voltage regulator power supply. It is widely used in telephone machine tools, game consoles, language repetition machines, Walkman, notebooks, cellular phones and other equipment.

Difference between charger and adapter:
Charger contains the function of the adapter, but the charger is also the internal flow, constant pressure and so on to meet the charging characteristics of the control circuit, the adapter of the charging control circuit generally on the host to complete. For example, PHS charger and laptop charger is actually just a power adapter, it is not included in the charge control circuit, charging control is in PHS and the internal computer completed.

The biggest difference between the charger and the adaptor is that the charger is just charging the battery, and the adapter can not only charge the battery, but also power the host

In a computer, adapters are typically placed in tab (also external) that can be plugged into slots on the motherboard, and the adapter information in the card is exchanged between the processor and the adapter-supported device. The power adapter is a small portable electronic equipment and electronic electrical power supply conversion equipment, generally consists of shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; The power adapter is especially important for mobile PCs because they do not have a battery. Most mobile PC power adapters can automatically detect $number alternating current (Hz). Basically all mobile PCs have external power, with a line and host connection, so as to reduce the size and weight of the host, only a very small number of models put the power inside the mainframe. There is a nameplate on the power adapter, indicating the power, input and output voltage and current indicators, especially to pay attention to the range of input voltage, this is called "Travel power adapter."
