It won't hurt the battery.
Wireless charging treasure magnetic charging is realized through the principle of electromagnetic induction, the surface of the charging treasure has a built-in coil, and the mobile phone has a built-in coil.
When the two are close, the magnetic field generated in the charger acts on the coil in the phone through the coil, thus achieving wireless charging, which does not cause harm to the battery.
When using a wireless charging bank, you should pay attention to choosing genuine products and avoid using fake and shoddy products. In addition, we should develop appropriate battery use habits, rational use of the charging bank, and avoid placing it on the charger for a long time, so as to avoid overcharging or over-discharging the battery.
