The answer is no, wireless charging technology is not an emerging technology, just because the loss in the charging process is large, the application field is small, and the popularity is not high. However, with the emergence of smart phones, wireless charging technology has been applied to the field of mobile phones, the principle is to use electromagnetic induction to convert electric energy into special energy, and then transfer it between magnetic fields. The method and technology of transmission is not important, the important thing is that it can charge the phone, compared with the traditional charging method, in addition to the charging efficiency is slightly lower, it does not need to use the data cable, in addition, there is not much difference, and it will not cause damage to the phone battery.
Harmful Because the charging voltage is relatively high, the damage to the battery when wireless charging is relatively high, because the voltage is relatively high, it can reach 14 volts, so it will cause the electrolyte to be damaged
