Few accessories earn their place in a bag as reliably as a good power bank. The best ones top your phone up fast, fit a pocket or a daypack, and last through the longest travel days.
Capacity, decoded
A 10,000mAh bank charges a typical phone roughly two times; 20,000mAh doubles that at roughly double the weight. Match capacity to how long you'll be away from an outlet.
Fast charging and ports
Look for a bank that matches your phone's fast-charging standard over USB-C, with enough ports to charge two devices at once. Pass-through charging lets you top up the bank while it charges your phone.
Travel and carry rules
If you fly, check airline limits — banks are usually capped around 27,000mAh and must go in carry-on luggage, never checked bags. A slim, pocketable design wins for everyday carry.
