The definition of switching power supply, power adapter and charger!
1. Switching power supply
As the name implies, a device that connects or disconnects voltage and current. The switching power supply is not only a disconnect device, but also a dual current mode (AC and DC), high-frequency operation, application areas: monitoring systems, dome cameras, security systems, Wait, switching power supplies are indispensable for electronic products.
2, power adapter
Power conversion devices, such as common mobile phone chargers, walkmans, reading machines, notebooks, routers, etc., are all called power adapters in a strict sense. The power adapter is small in size, easy to carry, separate from the theme, and has a wide range of application categories. According to the type of power supply, it is also divided into direct and AC output methods. There are more types. There are outdoor waterproof power adapters, desktop power adapters, and direct Plug-in power adapter, multi-channel power adapter, USB power adapter, etc.
3, charger
The most common current conversion device for charging electronic equipment is the USB charger, which can basically charge different electronic products with USB device plugs. In the usual name, some people call the power adapter the charger, and some people also call the charger. Power adapter, but the power adapter includes an extended charger, the charger does not include the power adapter, such as the power supply for surveillance cameras or routers, the power supply that needs to supply power to the device is usually called the power adapter, and the USB charger is in the design requirements There are still differences. Usb chargers must meet the needs of different frequency bands and different currents. For example, the current relatively popular fast-charge chargers are used for surveillance and cameras. Ball machine. The power adapter that supplies power to devices such as routers tends to stabilize the current.
For the switching power supply, the power adapter and the charger, the easier to distinguish is the switching power supply. The power adapter and the charger are more difficult to distinguish. The ones that are often contacted in life are basically not distinguished, and they are all called chargers. In fact, According to the difference of the power supply equipment, the charger is biased towards diversification and the power adapter is biased towards stability, but the power adapter also includes the charger!
