Power adapter FAQ

1. What is the difference between power adapter and Power Supply

Adapter, to be exact, what should be said about the device adapter. For example: power adapter of mobile phone, adapter of razor, etc. In a word, it's a device. And power, the meaning is different. Power supply, as the name suggests, is the source of electricity. There is AC power supply, such as our common household power supply. In general, power grid. There is DC power supply, such as dry battery and battery

2. Is the laptop power adapter a battery or a charger

The power adapter of the notebook, like the power components of the desktop computer, is a supporting AC power converter specially designed for the notebook, which can supply power to the notebook and charge the battery at the same time. It is a portable power supply.

3. Are desktop power adapters universal

As long as the voltage, socket and polarity are consistent, they can be used for each other, but those with small current cannot carry large load.

4. What is the difference between power adapter and voltage regulator
Power ADA pter (power adapter) is a small portable electronic equipment and power supply conversion equipment of electronic appliances. It is generally composed of shell, power transformer and rectifier circuit. According to its output type, it can be divided into AC output type and DC output type. Straightforward can be understood as a voltage converter, such as converting 110-220 V AC voltage to a fixed DC voltage.

The voltage regulator is a device that makes the output voltage stable. The regulator is composed of constant voltage, control circuit and servo motor. When the input voltage or load changes, the control circuit samples, compares and amplifies, then drives the servo motor to rotate, so that the position of the voltage regulator carbon brush changes, and the output voltage is stable by automatically adjusting the coil turn ratio.

5. Purpose of power adapter

Switching Power Supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instruments and meters, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, LCD, LED lights, communication equipment, audio-visual products, security, computer case, digital products and instruments and other fields .

6. What is the difference between DC power adapter and AC power adapter

DC power adapter is a kind of power adapter used to charge and use network extender, router, communication equipment, mobile phone, laptop and PSP. Since the internal components of laptop and PSP use DC, and our living electricity is AC, there must be a way to convert the living electricity into DC to supply power to the computer and PSP. DC power adapter is born in this case.

The common AC power adapter (hereinafter referred to as AC power supply) is usually equipped with the AC symbol on the outside. The internal of the AC adapter is mainly through the power transformer to complete the conversion output.

DC power adapter (hereinafter referred to as DC power supply) is DC. The internal part of DC adapter is composed of rectifier circuit. At present, the common AC power adapter on the router has a copper core (wire package). During operation, the power consumption will be lost in the form of reactive power, and the input voltage range of the power supply is very narrow, which can not adapt to a variety of use environments. The common DC power supply is adapter (such as mobile phone charger, also known as DC switching power supply), which is composed of rectifier IC chip and filter circuit, so the loss will be much lower.
