What is a power bank?

A power bank is a portable battery pack designed to recharge electronic devices on the go. Power banks come in various sizes and capacities, typically ranging from 3,000mAh to over 50,000mAh. The capacity determines how many times a power bank can charge your device before needing to be recharged itself.

How do I use a power bank?

Make sure your power bank has sufficient charge before taking it with you. Connect Your Device: Use the appropriate cable to connect your device to the power bank. Most power banks have USB-A ports for output, so you'll need a USB-A to USB-C cable that fits your device (e.g., Lightning for iPhones, USB-C for many Android phones).
