Design and size

The design and size is another important aspect to look for while choosing the best power bank. If you are looking for a power bank to just keep in your pocket, then it should be small and light. But if you want something which can be used to charge laptops or other gadgets, then you should go for a power bank with high capacity.

Brand name

Cables and adapters play a vital role when you want to charge your gadgets with your power banks. Although most of them come up with inbuilt cables for micro-USB or USB-C, but they might not support fast charging technologies like Quick Charge 3.0 etc. if the cable is long enough then it must also support such advanced features which make it versatile to work with any Android phone, an iPhone and even iPads plus android tablets if the cable is long enough else you would need to carry some extra cables with you at all times.

Coil cord
