The voltage and current output of the power adapter is too low, is it harmful to the mobile phone battery?

Nowadays, the configuration of 5G mobile phones is getting higher and higher, and the performance is getting better and better. Of course, the power consumption is also getting bigger and bigger with it, so it is more necessary to choose the appropriate power adapter output voltage and current. If the charger’s voltage and current are insufficient, it will be difficult to fully charge, and sometimes it will cause problems such as screen flickering and unexplained crashes.

Power Adapter

When the power adapter converts 220V AC to DC, the situation is a bit complicated. First of all, in the case of poor power supply performance, the input voltage needs to be further stabilized and filtered to ensure stable operation and stability. The compression voltage is divided into two parts. One part powers the mobile phone and the other part charges the battery. The part that powers the notebook computer is the same as when powering the battery.

You might think that if the output voltage and current of the power adapter are too high, it will exceed the maximum range of the phone and it will easily damage the battery of the phone. In fact, this is not the case. The current safety adapters on the market usually have a smart chip that can automatically adjust the current. If the current output by the charger is too large, it will adjust to the next level. When the current and voltage of the power adapter are insufficient, the load on the mobile phone line may increase. In this state, the phone heats up more than usual, which can easily damage the battery life of the phone.
