Best power banks for laptops

Charging a laptop needs a power bank with a USB-C port that puts out at least 60 W, and 100 W or more for larger laptops. Capacity of 20,000 mAh or above gives a meaningful top-up. Airlines allow up to 100 Wh in carry-on bags without approval.

Top 10 of 23 that qualify, from 103 power banks compared. Best known and best liked first.

Every pick fits, so the order is about what to look at first. Models that independent reviewers recommend come first, the most often recommended at the top. The rest follow, best known and best liked first, with the newest model of a line ahead of older ones. No brand pays to be listed or placed higher. Prices change daily, so we never print one; Amazon shows today's price.
