Power adapters are widely used, which determine the use and charging of many electronic and electrical equipment in our lives, especially convenient mobile devices, notebook computers, etc., so the quality of power adapters is a problem that we are concerned about. In fact, there are some problems in power adapters. Many quality problems.
1. The product identification is incomplete or non-standard.Labels should contain important information to guide the user in proper installation and use. Properly labeling products is one of the basic measures to ensure the safety of users' personal and property. Markers need to be durable and eye-catching. After normal use, the markings should not come off and the contents should be clean and distinguishable. Common problems in this regard are that there is no Chinese logo, no factory name or trademark, no model code or model specification, etc. It may be a fake and shoddy product.2. The heating under normal working conditions does not meet the requirements.The function of the power adapter is to change the voltage. During the voltage conversion process, a part of the electrical energy needs to be consumed due to losses. After the electrical energy is converted into thermal energy, part of the thermal energy is transferred to the surrounding environment through radiation, convection and conduction. Another part of the thermal energy is absorbed by itself, warming the temperature of the power adapter. So when the ambient temperature is too high, we should stop using the power adapter.3. Short circuit and overload, there are hidden safety hazards.In the case of output short circuit, capacitor or diode short circuit, the internal losses of the power adapter increase sharply, resulting in the temperature rise of each component. The design and application of electronic circuits should ensure that under abnormal working and fault conditions, the temperature rise of each part of the product cannot exceed the specified requirements, otherwise the consequences of a short circuit will be disastrous. Even bring fire.
