Our verdict

A pocket-sized bank whose built-in, bend-tested cable is the real selling point over a bare battery brick, provided you only need phone-level charging.

Overview

Anker packs a 10,000mAh cell and a built-in 30W USB-C cable into a body small enough for a pocket, built for phone-first travel charging rather than laptops, which need more wattage than this delivers.

The built-in cable is the detail worth noting since it removes the most common reason a power bank goes unused, which is not having a cable on hand. Anker rates the cable itself to survive over 10,000 bends, addressing the point where built-in cables usually fail first. Output tops out at 30W, enough for a fast phone charge but short of what a laptop needs.

10,000mAh capacity in a 4.3 x 2.6 x 1 inch body
Built-in USB-C cable rated for 10,000+ bends
30W output, 20W input for bi-directional charging
About 2 full iPhone 15 charges per bank

Who it's for

Phone-first travelers who want a compact bank with its own cable rather than packing a separate charging cord, and who charge phones or earbuds rather than laptops.

Pros and cons

Pros

Built-in cable, nothing extra to pack
30W is fast for a bank this size
Bi-directional charging recharges the bank itself at 20W

Cons

Built-in cable can't be swapped if it fails
Not enough wattage for laptop charging

Performance notes

30W output is rated to take an iPhone 16 Pro Max to 50 percent in about 27 minutes, roughly double the speed of a standard 5V/3A charger, and the same port supports 20W input for recharging the bank itself. Anker's capacity estimates put it at about two full iPhone 15 charges or ten AirPods Pro 2 charges per full bank, though the built-in USB-C cable means older Lightning devices need their own cable plugged into the spare port.
