Hi Mi Fans,
In the today’s world we all own Smartphones. We pamper them,take care of them, love them and obviously use them. But at times when our very loved smartphones are about to die on their batteries and there is no othersource to charge up the device, these portable gadgets come to the rescue andwe call them Power banks.

What are power banks?
A power bank is compact/portable device which can be used to charge our mobile phones, laptops, smart watches and lot more. Power banks can come in different capacities, sizes and dimensions but all of them serve the same purpose of providing us with an electrical source to charge up our devices when there is no other source is available.

The history of power banks!
The idea of power bankstarted when a student packed in a few AA batteries with a control circuit andput it in a box which was able to charge cell phones and pagers. This historic discovery took place back in 2001 where the student presented his work in the International Consumer Electronics Show, 2001, Las Vegas, Nevada, USA. This marked the birth of the power banks which we use in a day to day basis.

What basically is the concept here?
Basically, a power bank is constructed by combining lithium-ion cells of some defined capacity with a controlle rcircuit which controls the output and the input current of the power bank. Finally,the entire engineering is packed in a highly durable container along with some battery level indicators, charge level indicators, power switch etc.

How do the power banks work?
When a power bank is connected to a device having a lower input voltage than itself the power bankstarts charging the device. Power banks come with different capacities and different output ratings. The more the capacity more will be the number ofdevices it will be able to charge. The more will be the output rating the faster it will be able to charge up the devices considering the devices support the amount of input voltage given out by the power bank.

Conclusion:
Power banks have proved to be a really necessary gadget for us. They can save you hours from charging up your device at home when you need to go to work or school or college. Power banks enable us to charge up our devuces on the go. Thanks to the student who discovered this wonderful gadget for which we are now able to save our much time and efforts to keep our devices powered up.
