The Best Power Banks Compared — Every Size and Budget

Anker Prime 20,100mAh

220W max output, three ports simultaneously, TSA-approved, and an app to check remaining charge. Charges a MacBook and two phones at full speed — at the same time.

Baseus 100W 20,000mAh

100W USB-C PD output charges most laptops from flat to full. Massive 20,000mAh capacity, digital display showing exact percentage, and a price that makes the competition blush.

INIU 100W 25,000mAh

The largest capacity on this list at 25,000mAh — enough to charge most phones 6–7 times. Mini size relative to its capacity. 100W output, three ports, and a transparent design that shows the cells.

Anker Nano Power Bank 10,000mAh

Built-in USB-C cable — no cable to forget or lose. 10,000mAh in a palm-sized body that slips into any pocket or small bag. The one that actually goes everywhere because it weighs almost nothing.
