As we have technologically progressed as a society, the demand for more products to meet our needs and to complement our existing products have become increasingly prevalent. As we are using more tech in our day to day life, we have developed a dependence on the need to charge these devices; things like our cellular phone, wireless headphones, portable speakers, and many more objects. Due to this necessity, power banks have emerged and have effectively become the portable charger- all your device needs is a USB charging interface. 

We will now look into the world of power banks, and a few different forms of them:

Definition of a power bank

Power banks may be defined as portable batteries that use, "circuitry to control any power in and power out." They are able to be charged up in a traditional method by means of a USB cable. After the power bank has reached it's full charge capacity, it can then be used to charge battery powered items such as cellular phones, and many other devices that require a USB to charge. 


    Battery technology within a power bank

    High capacity lithium batteries are used within power banks, and as such they are able to hold a charge in order to be able to charge other devices. Lithium-Polymer and Lithium-Ion batteries are most commonly used for power banks but be prepared for other battery technology to be utilized within a power bank in the future. As for many new technological advancements, batteries are in fact quite crucial, as they are used for almost everything- ranging from electric vehicles, to our mobile phones. As a result of these advancements, it is highly likely that there will be spin-offs and additional features within power banks, such as our Hummer Power Bank range.

    The two most widely used power bank battery technologies are as follows:

    • Lithium-ion:   Lithium-Ion batteries have a higher energy density as they are able store more electrical charge in a given volume, and are much cheaper to manufacture- do note that they have issues with aging, as they deteriorate quite rapidly over time.
    • Lithium-polymer :   Lithium-polymer power banks do not suffer from ageing to the same extent as Lithium-Ion batteries, which makes them a better choice, albeit more costly and would not be recommended to someone with a smaller budget.
