Compact power bank with dual built-in cables

The Anker Zolo Power Bank packs a 20,000mAh battery into a 4.72 x 1.24 x 2.89 inch body weighing 12.85 oz. Two integrated USB-C cables rated for over 10,000 bends eliminate the need to carry separate cords. A USB-C port and a USB-A port add two more outputs for simultaneous charging.

Travellers needing one brick for phone.

It delivers up to 45W output, enough to push an iPhone 16 Pro Max to 57% or a Samsung S24 Ultra to 64% in 30 minutes. Four devices can charge at once from the dual cables and two ports. Buyers who want more storage capacity or faster laptop charging should look at something else.

Steady 45W output under continuous multi-device load

The cell sustains its rated power across all four outputs without throttling in typical use. Cables stay cool during extended sessions thanks to the 10,000-bend durability spec. An 18-month warranty covers the unit, and the welcome guide explains basic operation.

Questions about this item

Does the Anker Zolo Power Bank need a separate cable to recharge itself?

No, the two built-in USB-C cables also serve as the input path, so you can recharge the 20,000 mAh pack without carrying an extra cord.

Will the USB-A port still charge my older phone while the USB-C cables fast-charge a newer device?

Yes, all four outputs — dual built-in USB-C cables, USB-C port and USB-A port — operate simultaneously, letting legacy and current devices charge together.

How can I confirm the power bank is delivering its rated 45 W output?

Connect a compatible device such as an iPhone 16 Pro Max or Samsung S24 Ultra; the phone should reach roughly 57 % or 64 % charge in 30 minutes, matching the rated speed.
