Most portable power bank

Xiaomi is known for producing high-quality products and selling them at an affordable price. The 10,000mAh Mi Power Bank Pro is a prime example of that approach, hitting all the marks to make it our top pick for the most portable power bank overall. With its high efficiency, premium design, and street price of $28, it’s hard to beat. Pick up one or two of these, throw them in your bag and suitcase, and forget having to worry about running out of battery power while on the road.

Best power bank for road warriors

If you spend a lot of time on the road and value device preparedness, the Sherpa 100AC makes a trusty, if pricey, companion. Yes, at $299.95, you’re looking at a big investment. But that buys you two USB-C ports capable of fast-charging speeds, two standard USB ports, a Qi wireless charging pad, a standard U.S. 110V outlet, a full complement of cables, and a nifty status display and buttons for controlling various functions of the pack. The pack itself can be charged in just a couple hours. (Read our full review of the Sherpa 100AC Portable Power Bank.)

Between its capacity, recharge time, charging capabilities, USB-C, and the wide range of devices it can charge, the Anker Powercore+ 26800 PD is well worth its $110 price.
