Automatic charging of power banks is annoying! [Copy link]

Here's what happened. Because I had guests at home, I went to sleep in the hut. There was no socket near the bed in the hut, so I used a power bank to charge my phone. After plugging it in, I fell asleep. As a result, I kept hearing the sound of my phone plugging into the charger in the middle of the night. After hearing it several times, I was so annoyed that I got up and unplugged the charging cable, and then I slept more peacefully. . .

When the power bank detects that the charging current is too small, it will automatically cut off the power. What is the principle of automatic charging?

Just change the power bank

There is such a phenomenon. Before, the power bank could charge Apple mobile phones intermittently and the charging was very slow. It may be related to the charging protocol.

It feels to me that the phone is fully charged, and then it consumes some power while in standby mode. It detects that the power is low and starts charging again.

The battery is fully charged.

The power bank has a button, and charging starts only when the button is pressed. This type of power bank will disconnect after it is fully charged.

My power banks are all old-fashioned ones from several years ago, so they don't have this problem.

This type of power bank will also have voltage output at the port in standby mode, but the driving capacity is much lower than during normal operation. Once an increase in output current is detected, the main output channel will be automatically opened to provide high current.

Does this happen with all new power banks, or is it a rare occurrence? I feel like this feature has both advantages and disadvantages.

Mine has a button, but it will automatically start charging if you plug your phone in without pressing the button.

I'm not sure about this, I haven't used the new type.

My power banks all have buttons to check the remaining power. When you press them, an LED will indicate the remaining power. Obviously, you don't need to press these buttons to charge.

It should be like this. Turning off the charging reminder sound will have no effect.

It is true.

Repeated charging is not good for the battery.

The phone has charging management, so it is not so easy to break down

Although there is charging management, it is still repeatedly recognized as charging, and the agreement is still not set

Mine keeps getting less and less as I charge it, but my Android phone has no problem and can be used normally. It's really strange.

I have only seen a few examples of the dangers of chargers online, and I am already scared enough to ignore them.

A mobile phone needs to be charged almost every day. If it is fully charged 500 times, the battery will be useless and the phone will be broken.
