Setup
Charging the Power Bank

Press the power button on the side of the power bank to view the current battery percentage on the integrated display.
Operating Instructions
Charging Devices with Built-in USB-C Connector
Extend the foldable USB-C connector and plug it directly into your compatible device (e.g., iPhone 15 series, Samsung S22/23 series, iPad Pro/Air). The power bank will automatically begin charging.
Charging Devices with External Cable
For devices not compatible with the built-in USB-C connector or for simultaneous charging, use the additional USB-C port on the side of the power bank with an appropriate cable (e.g., USB-C to Lightning cable for older iPhones, sold separately).

Trickle Charging Mode
For low-power devices such as headphones or smartwatches, activate trickle charging mode by double-pressing the power button. This mode provides a slower, optimized charge to prevent overcharging and extend battery life for smaller devices.
Compatibility
The Anker Nano Power Bank is compatible with a wide range of devices, including:
- iPhone 15 Series
- Samsung S22/S23 Series
- iPad Pro/Air
- AirPods
- Other USB-C enabled smartphones, tablets, and small electronic devices.
For iPhone 14 series and earlier models (with Lightning port), a separate USB-C to Lightning cable is required for charging via the power bank's USB-C port.
Maintenance
- Keep the power bank away from extreme temperatures, direct sunlight, and liquids.
- Store in a cool, dry place when not in use.
- Clean the device with a soft, dry cloth. Avoid harsh chemicals or abrasive materials.
- Do not attempt to disassemble or repair the device yourself.
Troubleshooting
Device Not Charging / Slow Charging
- Ensure the power bank itself is sufficiently charged.
- Verify that the USB-C connector is fully inserted into your device.
- Check if your device is compatible with the USB-C connector. If using an older iPhone model (with Lightning port), ensure you are using a USB-C to Lightning cable connected to the power bank's USB-C port.
- If charging a low-power device, ensure trickle charging mode is activated.
- Some phone cases up to 0.19 inches (4.9 mm) thick are compatible. Thicker cases may interfere with the connection.
Power Bank Not Charging
- Ensure the charging cable is securely connected to both the power bank's input port and a functioning wall adapter.
- Try using a different USB-C charging cable and wall adapter.
