Anker Zolo Power Bank (20K, 22.5W, Built-in USB-C Cable) — Black
The Anker Zolo Power Bank (20K, 22.5W) doubles the capacity of its 10K sibling while keeping the same slim, cable-free design. A 20,000mAh battery delivers roughly 3.73 full charges for an iPhone 16 or 4.17 charges for a Samsung S24, and the built-in 7-inch bidirectional USB-C cable — rated for over 10,000 bends — means there’s no separate cord to pack. 22.5W fast charging brings an iPhone 16 Pro Max to 50% in 34 minutes or a Samsung S24 to 50% in 31 minutes, with support for 15W Samsung fast charging. Despite the larger battery, the unit weighs just 13.8 oz (391g), and pass-through charging keeps a connected phone topped up even while the power bank itself is recharging.
