It has to be said that technology is always breaking the cognition that ordinary people are used to. From fast charging to flash charging, wireless charging to reverse charging, we are witnesses and beneficiaries. Similarly, while enjoying technology, we will also have doubts, so today we will talk about some things about wireless reverse charging.

Wireless reverse charging refers to mobile phones and other devices that could only receive electromagnetic waves for wireless charging. Now they can send electromagnetic waves through wireless coils to charge other devices that support wireless charging. The mobile phone charger contains a small transformer. The mobile phone charger is marked with 6V, so it essentially includes two steps when charging: The first step is: the family’s AC 220V voltage is converted by the small transformer in the mobile phone charger It becomes a 6V voltage, and then the output voltage of the charger is 6V; the second step is to use the 6V output voltage of the charger to charge the mobile phone, that is to say, the input voltage when the mobile phone is charging is 6V. Therefore, the power of reverse charging is small and can only be used as an emergency.

Will reverse charging cause damage to the phone? In fact, reverse charging of the battery is discharge. If the battery voltage is within the allowable range, reverse charging is ordinary discharge. If the battery voltage is lower than the allowable voltage, it will cause over-discharge and damage the battery.

Therefore, you don’t have to worry too much about the damage to your mobile phone caused by reverse charging, as long as you prevent over-discharge.
