An essential thing for a smartphone is its battery. Without the battery, it will not run.

Whether you are traveling or are just unable to find a power source, with a power bank you are always good to go. It gives you the extra amount of juice that you need and stops you from being a wall-hugger. There are four things you should keep in mind while selecting a power bank: Capacity, portability, connectors, and price.

The capacity tells you how much charge is there inside the power bank. It is the most important feature and will depend upon your usage. Also, some power is lost during the process of charging your device. A power bank’s total output is about 70-75% of its rated capacity. You should keep this fact in mind while deciding. Portability is another criteria which you should give importance too. If the power bank is too heavy there’s no point in buying one.
