1, the reporter carried out a test, the results show that the wireless charger does exist radiation, the value is small but not without. Tests show that the radiation value of wireless chargers is less than that of mobile phones, such as Sharp SH8010C and Samsung i579, but when used with other electronic devices such as computers, WiFi, the cumulative effect cannot be ignored. In extreme cases, values above 2,500 can have a significant impact on health.
2, there is radiation is certain, otherwise the energy can not be transmitted across the space. The radio waves used for charging must be larger than the radiation power of the phone itself, otherwise the charging efficiency is too low. Calculated with a 1000mAh capacity lithium battery, 50% of the charging capacity is about 7~8Wh.
3, at present, some special mobile phones can be charged with wireless chargers, but the current technology can not be compared with the charging efficiency of wired chargers, and many wireless chargers are immature technology, charging will make the mobile phone unusually hot. Is the radiation value of wireless charger really greater than that of mobile phone? Beijing Telecom business Hall Da Jiao Ting shop work
1, hello, Huawei and Apple wireless charging can be universal, but it is best not to use it all the time, occasionally use a few times can, after all, two different brands of chargers, charging voltage and current are different, may cause battery damage. 2, wireless charging technology has gradually become the standard of smart phones, including Samsung and Apple brands. Still, its acceptance has not soared as much as expected. A common concern is whether wireless charging will have a negative impact on battery life. At first, the introduction of wireless charging aroused great interest among users.
No, wireless chargingDoes not degrade the battery's performance faster. Battery manufacturers design the amount of energy stored in batteries to determine the amount of electricity we can use. The manufacturer sets a fixed upper cut-off voltage and a lower cut-off voltage, and electrically cycles between the two voltage ranges, so long as we choose the right voltage range, we can cycle the battery thousands of times.
4, yes, as long as the device that supports wireless charging can be used, the difference is that the speed of charging is not the same. It won't hurt the battery.
5, the use of non-original charger charging is has an impact: has an impact on the battery: non-original are allThe voltage and current value is in a large range, because it has to adapt to many models of mobile phones, which is a universal type just like universal charging. It has a certain impact on the battery, which may not be fully charged, damage the battery electrode, cause the battery bulge to expand, and affect the battery life.
6, so don't worry about the problem of battery explosion, of course, if someone wants to die to change the battery capacity of the phone, or change the charging power of the phone to cause problems, this does not belong to the problem of the phone itself. At present, the mobile phone charging methods on the market are still very diverse, such as the most original line charging, and the current development trendHead very fast wireless charge.

5, yes, Apple mobile phone charging treasure, a set of power supply and charging functions in one portable charger. Generally, lithium batteries or dry batteries are used as storage units. Different from the internal configuration of the productBattery, also called external battery. Safety function: anti-overcharge, anti-overdischarge, anti-current, anti-short circuit and high temperature protection design. The output voltage range of the mobile power supply, although some devices have a USB interface, you also need to use the mobile power supply.
6, there are many charging banks that can charge Apple mobile phones, and now many charging banks, that is, mobile power supplies, are universal, but Apple has not yet produced charging banks. The following matters should be noted when using the mobile power supply: (1) The output voltage range of the mobile power supply, although some devices have a USB interface, they also need to use mobile powerSource power supply.
1, this wired charging will be better, some, because you wired charging, its charging efficiency will be higher, wireless charging, he will be slower. There is nothing good or bad. As long as the battery is used, the battery life will be lost, which is a common problem of every mobile phone, and it is inevitable.
2, wireless charging good. In wireless charging, the charger and the device to be charged do not need direct contact, easy to use, strong environmental adaptability, and avoid physical connectionSo there will be no interface wear, sparks, leakage and other problems, in addition to wireless charging can also achieve high voltage, high current, high power charging.
