Anker Zolo A1688 10,000mAh 30W Power Bank with Built-in USB-C Cable

At 10,000mAh, the Anker Zolo gives you a portable reserve of power for a busy day, a commute or a trip away.

Its built-in 13.7cm USB-C cable means there’s one less separate lead to pack when you need to charge a compatible device.

With up to 30W output, it’s designed to charge phones quickly while keeping the power bank itself convenient to recharge.

Why it makes sense

A power bank is most useful when it’s ready to hand and simple to connect. The Zolo combines its charging cable and battery in one unit, so you can take it out of a bag and connect a USB-C device without first finding a separate cable. That makes it a practical choice for keeping a phone topped up while travelling, commuting or spending a long day away from a socket.

Its 10,000mAh capacity offers useful backup for everyday mobile use. Anker states that it can provide up to two full charges for an iPhone 15, with the actual number depending on the device. Compared with carrying a power bank and a separate cable, the built-in design keeps the essentials together.

Buyers commonly praise the charging speed, battery life and compact design, and some also value having the cable built in. Feedback on value for money is mixed, so the clearest reasons to choose it are the integrated USB-C connection and the stated 30W charging capability.

Highlights

The USB-C connection supports up to 30W output and up to 20W input, allowing fast charging in both directions. Anker says a 20W fast charger can recharge the power bank in approximately 2.5 hours. For a phone, the manufacturer states that 30W charging can take an iPhone 15 from 0 to 57% in 30 minutes.

The built-in cable is tested to withstand more than 10,000 bends, making it suited to frequent everyday handling. There are two ports, and the power bank also has a low-current mode for small devices such as earphones. Its weight is 223g, a useful detail when choosing what to carry in a day bag.

Tips for day-to-day use

For the fastest recharge, pair the power bank with a 20W fast charger. To charge a low-current device such as earphones, double-tap the power button to enter low-current mode, double-tap again to exit. Pass-through charging is supported, so the power bank can recharge while charging a connected device at the same time.

Questions before you buy

How quickly can it charge a phone? The power bank supports up to 30W output. Anker’s example for an iPhone 15 is a charge from 0 to 57% in 30 minutes, charging speed depends on the device and charging conditions.

How long does the power bank take to recharge? Anker estimates approximately 2.5 hours when using a 20W fast charger.

Should you buy it?

The Zolo suits anyone who wants substantial phone backup in a single unit with its USB-C cable already attached. Its 10,000mAh capacity, up-to-30W output and two-way fast charging make it a practical fit for travel and everyday use, especially when keeping a separate charging lead to hand is less convenient.
