Anker Zolo – 20,000mAh power bank with built-in USB-C cable

Anker Zolo Power Bank (20K, 30W, Built-In USB-C Cable), model A1689, is a portable power bank for smartphones, tablets and other compatible USB-chargeable devices. Its 20,000mAh cell capacity provides an energy reserve for days when a wall socket is out of reach. A built-in USB-C cable, separate USB-C port and USB-A port allow use of either the attached cable or a separate charging cable suitable for your device.

Built-in USB-C cable for everyday use

An approximately 15.2cm USB-C cable is permanently attached to the power bank, removing the need for a separate cable when connecting a compatible USB-C device. According to Anker, it is designed to withstand over 10,000 bends. This built-in cable supports both charging a connected device and recharging the power bank itself.

A phone or tablet with a USB-C charging socket can connect directly to the attached cable. Devices with a different charging interface require a suitable cable connected to the power bank’s USB-C or USB-A port. The built-in USB-C connector does not plug directly into Lightning or Micro-USB sockets.

Up to 30W USB-C output

Both the built-in USB-C cable and separate USB-C port support up to 30W output when charging a single device. Supported output modes are 5V / 3A, 9V / 3A, 10V / 2.25A, 12V / 2.5A, 15V / 2A and 20V / 1.5A. Reaching maximum power requires a connected device that supports the corresponding charging mode.

USB-A delivers up to 22.5W individually, with output modes of 5V / 3A, 9V / 2A, 10V / 2.25A and 12V / 1.5A. When multiple devices are charged simultaneously, shared output is 5V / 3A, or up to 15W. Consequently, 30W USB-C fast charging is not simultaneously available across multiple connected devices.

Recharge input of up to 20W

Anker Zolo can be recharged through its built-in USB-C cable or separate USB-C port. Both support up to 20W input, with modes of 5V / 3A, 9V / 2.22A and 12V / 1.66A. Reaching maximum input power requires a suitable USB-C wall charger, which is not included.

Battery indicator and low-current mode

A digital indicator displays remaining battery charge as a percentage, helping you decide when to replenish the power bank. A dedicated low-current mode supports devices such as earbuds. Press the power button twice to activate this mode and twice again to exit.

ActiveShield 2.0 monitors temperature up to three million times a day and adjusts output power. Available charging power and charging modes supported by your connected device determine its charging rate. The package includes a power bank with built-in USB-C cable and a user guide.
