If all you want in the best power bank is a big battery, keep moving, because the Anker Prime Power Bank, with 27,650 mAh of battery packed inside, is more like a futuristic charging station than a simple power cell. It's on sale at Amazon for the lowest price ever, and if you want a power bank that can charge your laptop, phone, and more, multiple times over, Anker is the only power bank to consider.

The Anker Prime Power Bank has features you would never expect from a portable battery pack. It has a big OLED display that gives you detailed charging information. It can handle 250W total output, so charging the best Macbook is no trouble, and your smartphone will charge at its fastest speed. This battery is huge: it's close (99.5Wh) to the 100Wh legal limit for battery packs on an airplane. You can even charge the huge Prime Power bank extra fast if you use both USB-C ports on top.
