The power bank has become one of our everyday necessities in recent years. Not only are they required for tours and trips, but we also need them in the office, at home, during a power cut, while working from the café, and many other times. Carrying a good power bank allows you to have power for your devices no matter where you go. But choosing the perfect one is not that simple.
As you need to carry it with you, portability is an important factor to consider before buying a power bank. Small and lightweight power banks can fit within your pocket and you can carry them anywhere. Charging through a small power bank is also easy. Here, we made a list of 5 portable chargers which are the best compact power banks on the market.
With this article, we hope you can make an informed choice about your power bank. However, before that, let’s look at some of the factors that should come into play when you select one.
Buying Guide For The Best Compact Power Bank
Size
The size of a power bank mostly depends on its capacity. The higher the capacity, the bigger the size becomes. So, to get a pocket-sized power bank, you should choose one with a power range of 10,000mAh to 20,000mAh. And this capacity is enough to charge your device fully 2-5 times per recharge. However, to get higher capacity, you must use portable chargers that are larger than smartphones and are much more difficult to travel with.
Weight
Nobody wants to carry a heavyweight power bank. Though heavy power banks can carry a lot of charge within them, they are not appropriate for everyday use. Power banks weighing under 1 pound are considered lighter. They even can be carried in hand. Again, weight is dependent on the size of a power bank.
Shape
A power bank usually comes in a square, rectangle, or cylindrical shape. Among them, cylindrical ones are the most portable. You can put them anywhere inside your bag or purse. A square or rectangle power bank is also easy to carry if it is slim.
