Anker Prime 220W Power Bank: 20,100 mAh, 140W USB-C, Now $126

The Anker Prime Power Bank is a 20,100 mAh portable charger with 220W of total output across two USB-C ports and one USB-A port. It can charge two laptops simultaneously or power a phone, tablet and laptop together, and a single USB-C port can push up to 140W—enough to fast-charge a 16-inch MacBook Pro from empty to 50% in under half an hour.

A built-in color display shows real-time wattage output, how long until the bank is empty, and how much power each port is drawing. You can pair it via Bluetooth and monitor it in the Anker app, which also lets you set per-port wattage caps, name the bank and adjust the display timeout, though none of that is required to use it as a regular charger.

With its 20,100 mAh capacity the Prime can charge a MacBook Pro from 0% to 50% or an iPhone Pro Max three to four times, and it still falls under the TSA carry-on limit.
