Power banks are very common in our daily life, especially for office workers and students, who regard them as daily necessities. So, can we use a power bank while charging it? Why does a power bank stop working after a few uses? I will explain them one by one below, hoping to help you.

Can I use the power bank while charging it?

A power bank is a mobile power source that can be charged at any time. This is also based on your preference or purpose. If you are in a hurry, you can charge it anytime and anywhere. In order to solve your charging problem at the time, you don’t care whether it needs to be fully charged before use. Of course, charging and playing at the same time will cause certain damage to the phone, because the phone will be damaged if it is not fully charged. So it is not recommended to use it while charging. However, it can still be used in an emergency. However, it is still very convenient to have a power bank outside.

Why does the power bank stop working after a few uses?

The most important thing about a power bank is the internal battery cell. There are domestically produced batteries and imported batteries. Domestically produced batteries are divided into good and branded ones. Poor ones will start to decay after 10 cycles of charge and discharge, while imported ones can be cycled hundreds of times before the capacity begins to decay. However, if you buy a copycat or a black-hearted manufacturer, the so-called dry battery is basically broken after two times. Therefore, it is best to buy a power bank produced by a regular and well-known manufacturer, with guaranteed quality.

Can power banks be connected in series?

Power banks can be connected in series. Each power bank has a 5V USB output, so ten power banks have a 50V output. However, you need to pay attention to the following points:

1. It is best to use power banks of the same specifications

2. It is best if the power bank has a switch button. If not, it will not turn on when the USB cable is inserted because there is no load, or even if there is a load but all power banks are not connected, it will not turn on.

3. The most important thing is to make sure the USB cable is properly connected.
