Power Banks and Charging: What to Check

Capacity is not the whole story: ports and wattage matter too.

Capacity alone does not show whether a power bank will charge your devices quickly. Check the output wattage, USB-C or USB-A ports, supported charging standards and cable requirements. Compare real-world weight and size if you will carry it daily, and check airline limits before travelling. Choose a model whose output meets the needs of your phone, tablet or laptop.
