How to extend the service life of power adapter
Cold and heat protection. Do not place the charger in a place with too high temperature. High temperatures can shorten the life of electronic devices, damage chargers, and warp or melt certain plastic parts. Do not store the charger in a cold place. If the charger is working in an extremely cold environment, the increased internal temperature can cause moisture inside the charger and damage the circuit board.The service life of electronic products directly affects the cost performance of electronic products, so what do we need to pay attention to in the process of use? 1. Release static electricity during cleaning. Clean power adapters and charging ports regularly. Use wet cloth or ESD cloth, do not use dry cloth. 2. Waterproof and moisture-proof. As an electronic product, the corrosion and oxidation degree of the internal electronic components will vary if they are accidentally exposed to water or humid air when not used for a long time. 3. Anti-fall and anti-vibration. Mobile phone chargers are actually fragile parts, the internal parts can not withstand impact. Especially to prevent accidental landings during use. Do not throw, hit or shake the charger. Rough handling of the charger can damage the internal circuit board. 4. Cold and hot protection. Do not place the charger in a place with too high temperature. High temperatures can shorten the life of electronic devices, damage chargers, and warp or melt certain plastic parts. Do not store the charger in a cold place. If the charger is working in an extremely cold environment, the increased internal temperature can cause moisture inside the charger and damage the circuit board. 5. Resistance to effective chemicals. Do not use harsh chemicals, cleaners or strong cleaners to clean the charger. To clean the outside of the charger, wipe with cotton dampened with a small amount of anhydrous alcohol.

Check whether there is any problem on capacitance resistance inductance, such as the capacitance in bulge, had better change in time, lest leave hidden trouble. Pay attention to the power cord. When winding the power cord of the notebook, try to pay attention to avoid breaking the internal cable to form a break. If the external power supply does not power, then you can plug in the laptop battery to try, if the laptop can start normally, there may be a laptop power cord or laptop power adapter problem. Then test with a multimeter to find out if there is a problem with the laptop power cord, in order to simplify the difficulty of troubleshooting, do not try to open the laptop power adapter housing at first.

Does wireless charger have radiation to affect person?
Both are within safe limits, and the magnetic field generated by the charger is weak enough to charge the device without affecting nearby credit cards, video tapes and other magnetically recorded objects. However, try to avoid direct contact with the charging platform while charging.

What are the factors that affect the adapter voltage?
the switching power supply load short-circuit fault (especially DC/DC converter short-circuit or poor performance, etc.), at this time, first off all the load of the switching power supply circuit, check whether the switching power supply circuit fault or the load circuit fault. If the load circuit is disconnected and the voltage output is normal, it indicates that the load is too heavy; Or the switch power circuit is faulty.

The association between the power adapter and the charger
The charger usually refers to a kind of equipment that converts alternating current to low voltage direct current. It includes the control circuit that meets the charging characteristics, such as current limiting and voltage limiting. The power adapter is a power converter after voltage change, rectification and voltage regulation, and the output is DC. Now let's talk about what is a power adapter? What is a charger? What is the relationship between the two and the difference between them.

How to solve the power adapter interference?
To the external anti-jamming ability, such as surge, lightning strikes, should optimize the AC input and DC output port lightning protection ability. The combination of zinc oxide varistor and gas discharge tube can be used to solve the lightning strike. For electrostatic discharge, TVS tube and the corresponding grounding protection, increase the distance between the small signal circuit and the housing, or use anti-static interference devices to solve the problem.

What are the factors that affect the adapter voltage?
switching power supply load short circuit fault (especially short circuit or poor performance, etc.) DC/DC converter, at this point, first disconnect all the load switch power supply circuit, checking is switching power supply circuit failure or malfunction with the load circuit. If the load circuit is disconnected and the voltage output is normal, it indicates that the load is too heavy; Or the switch power circuit is faulty.
