Power bank output charge: 

Before you buy a power bank 20000mah., You should think about the rate at which the charge is delivered. The rate of the charge affects the entire time of the charge.

The rate of the charge varies from one device to another. The USB port can pass a charge off o.5 of an amp of current while a tablet can get 2.5 amp of current.

The rate of charge needs to be faster. The faster the rate of charge, the quicker the device will be charged.

Ports available:

The number of ports available on the power bank can influence the charging of the connected devices. Earlier the power banks had only one port.

But the power banks available at present can have one or two or sometimes even more ports. Having more ports is an advantage so that you can connect more devices and start charging them simultaneously.

But the main disadvantage is that the power bank may not supply enough current to every port and it may take longer for the devices to get fully charged.

The current shared among the devices connected to various ports will slow down the charging.

Size & weight:

The size and weight of the power bank can definitely affect the usage of the power bank. If the power bank is heavier and bulky in size then you have to keep it at one place all the time while using it.

The power banks that are heavier in weight and bulky in size cannot be used while traveling. There are lightweight and compact power banks available in the market which can be easily moved and used even during the journey.

Technologies used:

  • Lithium-ion: The batteries have high power density and after using them for long, the batteries cannot be charged at all. The batteries are heavy and bigger in size. The cost is lower.
  • Lithium polymer: The batteries are strong, flexible, and durable for a long time. The batteries are lightweight and compact in size. The cost is reasonable.
  • Most power bank manufacturers specify the battery type but on the same brands, the type of batteries may not specify.

Connectors used for charging:

The output current passed by the power banks remains universally the same.

The current is passed using USB – Type-A. The USB connectors are commonly used as an interface to charge the devices.

You have to keep in mind the above-given points before you decide to buy the power bank for your home or office.
