Charger usually refers to a device that converts alternating current into low-voltage direct current. It contains control circuits that meet charging characteristics, such as current limit and voltage limit. Chargers are widely used in various fields, especially in the field of life is widely used in mobile phones, cameras and other common electrical appliances.
Power adapters on the market common power adapters are at the end of the variable voltage, rectifier and regulated power converter, the output is DC, in the case of meeting the power can be understood as low voltage regulated power supply. It is widely used in telephone subsets, game machines, language Repeaters, walkmen, notebooks, cellular phones and other devices.
What's the difference between a charger and an adapter? The charger contains the functions of the adapter, but the charger also has a constant current, constant voltage and other control circuits to meet the charging characteristics. The charging control circuit of the adapter is generally completed on the host computer. For example, the PHS charger and the laptop charger are actually just a power adapter, which does not include the charging control circuit, and the charging control is completed inside the PHS and the computer.
