If you opt for a small capacity, you'll only be able to charge a single device at a time, and, depending on the device and if you're using it, you might not even be able to fully charge once.
If you plan on charging multiple devices or using your devices heavily, it's better to choose a high-capacity power bank. However, keep in mind that a higher capacity usually means a larger and heavier power bank, so if portability is important to you, you may want to choose a smaller capacity power bank.
All power banks feature mainly two types of batteries: Lithium Ion (Li-ion) and Lithium Polymer (LiPo). Li-ion batteries come in a cylindrical-shaped plastic case. These batteries require low maintenance and are cheaper than LiPo batteries but have a higher energy density.
