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.
Wireless charging, which was awarded 20 patents in 2007, allows a variety of devices to use a charging base station, cell phones, MP3 players, power tools and other power adapters. Inductive coupling will act as a bridge between charging stations and devices, using magnetic fields generated between coils to transmit power. Most current chargers, such as the iPod and iPhone, charge the device's built-in battery through direct contact with a metal wire. The advantage of wireless charging technology is its convenience and versatility. The disadvantages are that it is inefficient and can only provide electricity.
The body has a strong response to electric fields, but little to no response to magnetic fields, so this system does not affect human health.
As an electronic charging product, the charger itself can not avoid radiation, so wireless charger radiation is inevitable. But the current wireless charger power is small, charging time is long, the radiation generated is small, should not cause great harm to people.

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.
