Will a fully charged power bank break if it is not used all the time?

I don’t know if you have any experience like this. There are several power banks at home, but only one or two of them are used frequently, and everything else is basically idle. The "destiny" of these idle power banks is basically that the power is left empty.

Then the question is, will these idle power banks break if they are not used?

Before the power bank is left unused, should it be fully charged or not? Today Carol will answer this question

If the power bank is left unused, will it break if not used?

It has a lot to do with the environment where the power bank is placed. Excessive humidity or temperature is not suitable for storage. The storage environment should be dry, and the power bank will not be damaged so easily if left in a dry environment.

However, the power storage effect may not be as good as the power loss is fast. This is because the power storage unit of the power bank will slowly "necrot" if the battery is not used for a long time.

Of course, some poor quality power banks are not ruled out, and those that are broken after a short period of time can be checked before use.

Let's talk about full power storage and dissatisfaction power storage. The current power bank basically uses lithium batteries.

Lithium battery cycling between 20% and 80% is the state with the longest battery life. When the battery reaches 20%, start charging, do not deep discharge to 0%. At the same time when the battery is charged to about 80%.

After the charging is completed, the effect of charging to 100% is not significant. In short, whether the power bank is being used or left unused, it should be recharged after a period of time.
