Have you ever been out running errands only to see your phone’s battery at 1%? Anyone with a smartphone knows how important it is to carry around a backup power source.

Smartphones run out of battery notoriously quickly, and it can be frustrating. Luckily, external power banks are a great source of power, and there are plenty of different ones to choose from.

Choosing a power bank is difficult. When deciding which model to buy, there are a lot of different things to consider. The best external power banks are portable, so you can put them in your bag and carry them around easily. Size is another factor to keep in mind. Some external power banks are small in size, while others are significantly large.
