Power Bank: Top 7 Best Power Bank with Solar Charger


A Power Bank can be said to be a portable battery that uses circuitry to control any power in and power out. They can be charged up using a USB charger when power is available, and then used to charge battery-powered items like mobile phones and other devices that would normally use a USB charger.

Power Banks

Power banks work by use of sophisticated electronics to manage taking in charge from a charger and storing it in a battery and then charge other devices. A power bank is not just a simple battery, they use sophisticated electronic circuitry to manage being charged and then charge other devices.

Types of Power Bank

We have two types of power banks which are standard and solar power banks

  • The Universal or standard power bank: These power banks are the normal power bank portable chargers that are available in the stores and online. They are charged from the normal USB chargers.
  • The Solar power bank: As the name implies, Solar power banks can use sunlight to charge up. They have photovoltaic panels. Solar power banks are really only able to trickle-charge the internal battery when placed in sunlight because the solar cells are relatively small, but this can be a very useful function.

How long a Power Bank can last

There are two main types of a lifetime that are associated with power banks which are

  • The Charge discharge cycles: All rechargeable batteries will gradually wear out. Normally the lifetime of batteries is quoted in terms of the number of charge-discharge cycles they can undergo before their performance falls by a given degree. However, Some cheaper power banks may only have a life of 500+ charge-discharge cycles, but good power banks will have lifetimes of more charge-discharge cycles.
  • The Self-discharge time: All batteries cell, either rechargeable or primary, have a certain level of self-discharge. For rechargeable batteries with their own control circuitry, a small amount of power is needed to keep these circuits alive. As a result, there is only a definite time that a battery will remain charged.
    Good power banks can hold a charge for up to 5 months with only a small loss of charge, but low-quality power banks may only retain its charge for about a month.
