The Anker Zolo is the brand-name option in this ranking, and the listing puts its emphasis on output rather than capacity: 20,000mAh with 30W USB-C charging, which is fast enough to top up a phone at close to its maximum rate and capable of charging smaller laptops slowly.

Anker is the most established name in this category, which is why its listings tend to sit a little above the unbranded packs per mAh. At the time of collection the Zolo carried 13,878 ratings at 4.5 stars. As with every pack here, the rated capacity is measured at the cell rather than at the port. Everything here comes from the Amazon listing rather than our own testing.
