Anker Zolo Power Bank (20K, 22.5W, Built-in USB-C Cable) Black

The Anker Zolo Power Bank is a 20,000mAh portable charger with a USB-C cable built directly into the unit, so there’s no separate cord to pack or lose. It suits commuters, travellers, and anyone who needs a full day of backup power for a phone or tablet. The built-in cable and 22.5W output make it a practical everyday carry rather than an occasional emergency-only device.

Technical Specifications

Capacity & Power

• Battery capacity: 20,000mAh. For instance, this typically supports 3 to 4 full smartphone charges depending on the device.
• Maximum output: 22.5W. Additionally, this output spans both the built-in USB-C cable and the extra USB-A port.
• Output profile: 5V/3A, 9V/2A, 10V/2.25A, 22.5W max. Furthermore, this profile stays compatible with 15W Samsung fast charging.

Physical Design

• Weight: 13.8 oz (approximately 391g). Consequently, the power bank stays portable enough for daily bag or pocket carry.
• Built-in cable: 7-inch USB-C cable, integrated into the housing. Notably, this cable withstands 10,000 bend cycles.
• Ports: 1 built-in USB-C cable plus 1 USB-A port. As a result, a second device can charge at the same time.

Charging Behaviour

• Pass-through charging: Supports charging a connected device while the power bank itself recharges from a wall adapter. However, charging speed for both may slow slightly during pass-through use.
• Compatibility: Works with USB-C and USB-A devices, including phones, tablets, and other USB-powered electronics.
• Warranty: 18-month manufacturer warranty included.

Use Cases

Will this work without carrying a separate charging cable?

Yes. The built-in 7-inch USB-C cable means the Anker Zolo Power Bank charges USB-C devices on its own, without needing a spare cable in a bag.

Is it fast enough for modern smartphones?

The 22.5W output charges most current phones to 50% in around 30 to 35 minutes. However, exact speeds vary with the phone’s own charging limits, since the slower component caps total output.

Can it charge two devices at once?

The built-in USB-C cable and the USB-A port both draw from the same 22.5W maximum output, so simultaneous charging works but each device gets a reduced share of total power.
