A power bank and a portable charger are essentially the same type of device, both designed to charge electronic gadgets on the go. However, there are subtle differences in their typical usage and capacity.

A power bank generally refers to a higher-capacity portable energy storage device that can charge multiple devices simultaneously and multiple times before needing a recharge. It is suitable for travelers, adventurers, or heavy users who rely on many devices and need long-lasting power or multiple charges. Power banks often come with features like multiple USB ports, fast charging technology, and sometimes built-in cables or wireless charging.

A portable charger usually means a smaller, more compact device with lower capacity, designed for quick top-ups of a single device during daily commutes or short trips. It is lightweight and easy to carry, ideal for emergency boosts but not for extensive use over multiple days or multiple devices.

In summary, choose a power bank if you need high capacity and versatility for multiple devices or extended periods. Opt for a portable charger if you want something light and handy for everyday short-term power boosts.
