Will power bank damage the phone battery?

Compared with the original mobile phone charger, charging the mobile phone to the mobile phone does damage the mobile phone battery, but the incidence of this situation is not high, and has a direct relationship with the user’s choice and usage habits.

Generally, there are two types of charging methods for power bank, one is ordinary charging, that is, 5V1A, which has the circuit protection mechanism of the mobile phone itself. This charging method generally does not cause damage to the mobile phone battery, but the current power bank source also has a fast charging. The function of this type of charging may cause damage to the battery of some mobile phones.

Generally speaking, in the process of mobile phone battery design, the manufacturer will test its life under a certain current condition, which can be understood as the service life of the mobile phone battery. If the discharge current value recommended by the manufacturer is exceeded, the battery life may be reduced. Excessive current charging will inevitably lead to a decline in the life of the mobile phone battery.

Of course, this is the case with the use of genuine power bank, if you are using a copycat power bank supply, then there are more issues to consider, such as whether the current output flag is true, the internal protection mechanism of the power bank . Some time ago, there was a situation of power bank explosion in the copycat. Therefore, for the user’s own safety, it is recommended that you buy a genuine power bank supply. At the same time, if you do not know the battery limit of the mobile phone, try to charge the mobile phone by ordinary charging.
