1.After the production of the power adapter is completed and before it flows to the market,it will undergo aging testing to ensure product quality. When the power adapter that has undergone aging testing flows into the hands of consumers, there are basically no fault problems. In addition, the lifespan and quality of the power adapter that has undergone aging testing can be guaranteed.Power adapter aging test cabinet2. Power aging belongs to Environmental Stress Screening (ESS), which is a popular quality and reliability assurance method for modern high-tech electronic products. As the name suggests, environmental stress screening is the use of external environmental stress to expose potential defects in electronic hardware caused by weak components and poor processes in the manufacturing process. Then, various appropriate inspection or testing methods are used to identify and remove these defective products, or corrective actions are taken for maintenance, in order to improve the man...

The significance of aging standardsPower adapter is a crucial component in electronic products, and its quality directly affects the stability and reliability of the product. In order to ensure the quality of power adapters, a series of aging standards have been established. Aging testing can simulate various environmental factors and loads experienced by power adapters during long-term operation, accelerate the aging process, and test the reliability and stability of the adapter in a relatively short period of time.6W WALL AC DC ADAPTERAging testing standardsThe aging test standards vary according to different product types and usage environments, mainly including the following:1. Industrial standards: Industrial standards require products to pass aging tests to ensure product quality. For example, power adapter products can be tested according to standards such as GB/T 4943.1-2011 "Safety of Household and Similar Electrical Appliances - Part 1: General Provisions" and GB/T 9254-2008...
Switching power supplies have the following main technical indicators:500W Switching Power Supply1. Output powerThe output power of a switching power supply refers to the electrical energy it outputs, usually expressed in watts (W). The size of the output power directly determines the range of use of switch mode power supplies, for example, the maximum power of computer power supplies is generally between 300W-1000W. The size of output power can also affect the price and reliability of switching power supplies.2. Output voltageThe output voltage of a switching power supply refers to the magnitude of the voltage output from its output port, usually expressed in volts (V). Different devices and scenarios require different output voltages, for example, laptops need to output a voltage of 19V, while mobile phone chargers need to output a voltage of 5V.3. Output currentThe output current of a switching power supply refers to the magnitude of the current output from its output port, usually...
Recently, many people have reported that they often buy fake label power supplies, which leads to their devices not being able to operate and meet the requirements. While helping to solve the problem of fake labels, I also deeply doubt why there are more and more fake label power supplies on the market?1. Intense market competitionIn this fiercely competitive market environment, some unscrupulous merchants, in order to attract the attention of consumers, are willing to improve the competitiveness of their products by falsely labeling the parameters of the power supply. They take advantage of consumers' lack of knowledge about power supply and intentionally exaggerate the output power, conversion efficiency, and other parameters of the power supply, leading consumers to mistakenly believe that they have purchased a high-performance power supply.2. Cost factorsSome unscrupulous merchants, in order to reduce production costs, use inferior battery cells and circuit designs, resulting in t...
The seemingly inconspicuous electric vehicle has repeatedly triggered deadly fires, causing serious damage to life and property. 80% of electric vehicle fires are caused by illegal charging.1. Improper charging operationCharging is prohibited in public spaces such as stairwells, fire exits, and evacuation safety exits. Charging is also prohibited indoors and near flammable materials. During the charging process, the charger generates a large amount of heat. The battery and its charging device should be placed in an open and well ventilated area for charging. Do not cover the charger or battery with combustible materials, as heat accumulation can easily cause a fire.2. Privately connecting and randomly pulling wires for chargingIt is prohibited to connect or pull wires privately. If the diameter of the charging line is too small and no short circuit or overload protection device is adopted, it is easy to cause a short circuit or heating of the line, which can lead to fire accidents.3....
