If you travel with a phone, earbuds and a watch, or add a laptop to that list, this page is for you. A power bank is the difference between hunting for an airport outlet and sitting wherever you like.
The four picks run from a slim, fast-charging bank that fits a jacket pocket to a laptop-class battery that can power a workday on a plane, with a two-pack for couples and a magnetic Qi2 bank for iPhone owners in between. They come from roundups at Travel + Leisure and WIRED, matched to the exact Amazon listing. The one thing to check before buying is the airline rule: power banks must travel in your carry-on, never in a checked bag, and large batteries have watt-hour limits that vary by carrier. The Wh figure is printed on the bank, so compare it with your airline's policy before you pack a big one.

Straight answers to what travelers ask most about power banks.
Can I bring a power bank on a plane?⌄
Yes, in your carry-on only. Lithium batteries are not allowed in checked luggage. Most airlines allow banks up to 100Wh without approval and larger ones up to 160Wh with airline permission. The watt-hour rating is printed on the bank; check your carrier's policy before flying.
How many mAh do I need for a week of travel?⌄
For a phone, a 10,000 mAh bank gives a couple of full charges and is easy to refill nightly, so it covers most trips. If you want to charge a laptop or several devices between outlets, step up to 20,000 mAh or more, accepting the extra weight.
Will a power bank charge my laptop?⌄
Only if it supports USB-C Power Delivery at a high enough wattage. Most phone-class banks will not. Among our picks, the Anker 25,000 mAh 165W is built for laptops; the others are for phones, earbuds and tablets. Check the Amazon listing for the current output spec.
