Best Power Banks 2026 — Top 10

The Prime is the largest bank Anker sells that still fits under the 100Wh airline limit: 27,650mAh at the maker's own published 99.54Wh, with 250W of total output split across two USB-C ports and one USB-A. Each USB-C port can deliver 140W on its own under PD 3.1, and the bank recharges at up to 140W through a single port, refilling in under 43 minutes by the maker's figure. A smart display and app connection show per-port draw and remaining capacity. It is covered by a 24-month warranty, and Anker prints its support phone number and email directly on the product page. Amazon owners rate this configuration about 4.4 out of 5 across several thousand reviews.
