Universal Lithium Battery Charger
Power adapter is also called external power supply (switching power adapter). It is a kind of power supply transformer for small portable electronic equipment and electronic appliances. Its emergence is due to the fact that in real life, electronic devices can not directly use household electricity, because the power supply voltage used at home is 220 v, And the general electronic products generally need power supply voltage of 5 V to 20 V or so

Description
Lithium marine battery charger Power adapter is commonly used in small electronic products such as mobile phone, LCD and laptop. Generally, it is 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; According to the connection mode can be divided into wall and desktop. It is widely used in telephone, game machine, language repeater, Walkman, notebook computer, cellular phone and other equipment.

Computer power adapter
Power adapter is widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration heating, air purifier, electronic refrigerator, LCD, LED lamps, communication equipment, audio-visual products, security, computer chassis, digital products and instruments, And it plays an important role in these fields. What are the functions of power adapter?
Function of power adapter
Generally speaking,pulse charging lithium ion batteries, the function of power adapter is transformer and rectifier. Household AC is 220 V, while our computer land is 12 V DC (as if it is), so we can be sure that the power adapter is a transformer and rectifier. The adapter is a transformer, so we should all know that the AC 220 V is transformed through the transformer, and the DC is transformed through the rectifier. There is consumption here, and these consumption will be converted into heat, so the heating of the power adapter is normal. The transformer is made of silicon steel sheet. After the transformer is electrified, it will produce magnetic flux. The magnetic flux will cause the force between the silicon steel sheets to act, thus producing a buzzing sound. This is normal. But the sound of the earth is abnormal because of many reasons: 1. The AC voltage is unstable. 2. The chip is broken. 3. Turn to turn short circuit. 4. Component damage, etc. By the way, the function of adapter is to convert alternating current into direct current
Generally, the power adapter with large space is built-in. Generally, the size of the adapter is not small. The small size machine is external. In order to save space, it is also convenient to replace. The adapter uses commercial power, the voltage is relatively high, and it is dangerous to put it inside the machine.
