Best portable chargers for travelers
Capacity is not the only number that matters.
What to compare
Capacity in mAh or Wh, output ports and speeds, weight, and whether it can charge a laptop.
Flying
Airlines restrict power banks by capacity and require them in cabin baggage. Check your airline’s current limits before you travel.
Our picks
We have not tested these products ourselves. The picks below come from published reviews and roundups, and some are written by sellers, so we treat them with care. Models and prices change, and many are sold mainly in North America: check the current version, price and compatibility where you live before you buy.
Anker 737 (24,000 mAh): for laptops
A high-output model that one review says can run a large laptop at full speed. It is heavy.
Baseus Blade Pro and Anker 87W: slimmer laptop options
Both are named for charging laptops, with several ports. One runs hot at full power.
Iniu 10,000 mAh models: compact for phones
Small and light, with a built-in cable on some versions. About one to two phone charges.
Anker MagGo 10K: for magnetic phone charging
Picked first in one roundup for fast magnetic charging, but heavier than it looks and pricey.
The review explains that you usually get about 70 to 80 percent of the rated capacity. Laptops generally need 60 W or more. Buy from established brands, because cheap batteries can be a safety risk.
