The size can be an important factor. Power banks that are too large can be inconvenient since you need to carry them with you. In most cases, the size is related to its capacity, so it is up to you if you are willing to carry a power bank that is pretty big.
Nevertheless, power banks should also have a size that is related to the size of the device that it charges. For example, if you are planning to charge your smartphone, the power bank should be able to fit in your pocket. A laptop power bank should be bigger.

Additionally, the device you want to charge also determines the capacity. For a laptop you would need a power bank that has a capacity of at least 30.000 mAh, while for a smartphone it is enough 3.350 mAh.
