Buying Guide For Power Bank

Let us understand how power bank functions

Power banks are defined as portable batteries that use a complete circuit to control any power in and power out. The Power banks are charged using the main switch and then used for charging the phones or other devices. 

Power bank’s principle depends on various factors mentioned below:

1. Charge-Discharge Loop

The secondary type of cells is rechargeable, and as you are using it for a long time, it gradually wears out. The life of a battery depends on the number of charges cycles it can undergo before the performance of the battery starts degrading. 

2. Self-Discharging 

The battery levels have their own time of self-discharge, whether you charge up the device or not. It requires a small amount of energy to keep working. And, the battery remains charged for a certain time limit.

A good power bank can last up to 6 months with a small loss of charge, and on the other hand, the lower quality power bank cannot retain the charge for a month.
