Portable chargers, or power banks, have become essential for staying connected on the go. Whether you need to charge a smartphone, tablet, or laptop, finding the right power bank involves considering capacity, speed, portability, and more. This guide simplifies the selection process to help you choose the best power bank for your needs.
1. Capacity: Matching Your Usage Needs
Capacity is the power bank’s ability to store energy, measured in milliampere-hours (mAh). The higher the capacity, the more charges it can provide.
