Electronic Power Supply

A charger is a common charging device that converts electrical energy into DC energy and outputs the electrical energy to electronic devices such as cell phones, tablets, digital cameras, etc. through a USB cable that connects the charger to the electronic device, thus enabling the charging process. The charger does not require the use of a computer or other device to charge, it simply needs to be plugged into a wall outlet.

The difference between a good quality power supply and a poor quality power supply mainly includes the following aspects:

1. stability: good quality power supply using high-quality electronic components, design and manufacturing process, to maintain the output voltage, current and power supply stability is higher, not easy to appear sudden changes or fluctuations. Poor quality power supply is often electrical harassment, voltage fluctuations, current noise and other problems, which may adversely affect the operation of the equipment.

2. protection function: good quality power supply usually has a variety of protection functions, such as short-circuit protection, overload protection, over-voltage protection and over-temperature protection. Once the abnormal situation occurs, the power supply will automatically power off to protect the equipment to prevent damage to the equipment. Poor quality power supplies often lack this protection function, which may cause damage to the power supply or equipment.

What to do when the power supply fails

1. Check if the power supply and power cord are working properly. After confirming the power supply failure, stop using the power supply immediately and unplug it to avoid power leakage and short circuit to damage other equipment or cause fire.

2. If the power supply has a heat sink, check if there is dust or debris blocked in the heat sink. Cleaning out all dust and debris will improve the power supply's heat dissipation and reduce the possibility of overheating and failure.
