How does power bank works?

The working of a power bank can be understood through its structuring as shown below in figure 1. A battery form into which power is passed through the main power source or through a USB charger. The purpose of the device is to store the gained power so that it can be passed onto other devices later on. Along with the batter, the device comprises of some other sophisticated electronic setups as well that are aligned to manage all these operations. A power bank has an input socket that is dedicated to receiving power from a wall or USB socket. Typically, a power bank uses Mini or Micro USB sockets for charging.

The Mini socket is for the input of power while the full-sized USB socket is for output of power. It is advisable to read the manual in advance to get oneself aware of all possible specification before going into any trouble.

Management of charging and discharging of a power bank is a crucial factor in controlling its functioning. The components that are employed for the composition of the power bank are:

  1. Lithium-polymer: The batteries with Lithium polymer are more flexible and robust. The reason is because of their perfect shape and size. Power banks are generally lightweight which makes them capable to last longer as they bear a lower chance of suffering from any electrolyte leakage. This enables them to be carried with oneself at any time and anywhere.
  2. Lithium-ion: The component offers power bank a high power density. This lowers the cost of the product as they save them from exhibiting memory effect (An effect due to which batteries become difficult to charge with time). Lithium-ion power banks are less expensive as compared to Lithium polymer.
