Best Portable Power Banks

Portable batteries for phones, tablets, travel, and emergency charging without overbuying.

Updated June 1, 2026

A 10,000 mAh power bank is the useful default for most people. It is small enough to carry and large enough to matter.

For laptops, capacity is not enough. You also need USB-C output wattage high enough to charge the machine while it is being used.
