2. Setup
2.1 Charging the Power Bank
Before initial use, fully charge your Ntaanoo MP51 Power Bank. Connect the built-in USB-C cable or an external USB-C cable to the power bank's input port and plug the other end into a compatible USB power adapter (not included). The digital display will show the charging progress.

3. Operating Instructions
3.1 Magnetic Wireless Charging
For magnetic wireless charging, ensure your device is MagSafe compatible (iPhone 12 series or newer) or has a MagSafe compatible case. Simply align the back of your device with the magnetic ring on the power bank. The strong magnets will securely attach, and charging will begin automatically. For optimal performance, remove any non-MagSafe cases.

3.2 Wired Charging
The Ntaanoo MP51 offers multiple wired charging options:
- Built-in USB-C Cable: Pull out the integrated USB-C cable and connect it directly to your device's USB-C port. This supports up to 22.5W fast charging.
- Additional USB-C Port: Use your own USB-C to USB-C cable to connect to the dedicated USB-C output port on the power bank for charging other devices.
3.3 Using the Foldable Stand
The power bank features a convenient foldable kickstand. Gently pull out the stand from the back of the power bank. You can then prop up your device (while magnetically attached or separately) in either portrait or landscape orientation for hands-free viewing, video calls, or media consumption.

3.4 Charging Multiple Devices
The Ntaanoo MP51 can charge up to three devices simultaneously. You can combine magnetic wireless charging with the built-in USB-C cable and the additional USB-C output port to power your phone, earbuds, and another device at the same time.

4. Maintenance
4.1 Safety Features
The Ntaanoo MP51 is equipped with multiple built-in protections to ensure safe charging:
- Overcharge Protection: Prevents damage from excessive charging.
- Temperature Control: Monitors and regulates the device's temperature during operation.
- Short-Circuit Safeguards: Protects against electrical shorts.
It is normal for the power bank to experience slight heat during magnetic charging. This is a standard characteristic of magnetic charging technology and is completely safe.

To maintain the longevity and performance of your power bank:
- Keep the device dry and away from moisture.
- Avoid exposing it to extreme temperatures (hot or cold).
- Clean with a soft, dry cloth. Do not use harsh chemicals.
- Store in a cool, dry place when not in use.
5. Troubleshooting
If you encounter issues with your Ntaanoo MP51 Power Bank, consider the following:
- Power Bank Not Charging: Ensure the charging cable is securely connected to both the power bank and the power adapter. Verify the power adapter is functioning correctly and the power outlet is active.
- Device Not Charging Wirelessly: Confirm your device is MagSafe compatible or has a MagSafe compatible case. Remove any non-MagSafe cases that may interfere with the magnetic connection. Ensure the power bank is sufficiently charged.
- Device Not Charging Via Cable: Check that the built-in USB-C cable or external cable is fully inserted into both the power bank and your device. Try a different cable if available.
- Slow Charging: Ensure you are using a compatible fast-charging adapter for the power bank itself. For device charging, verify your device supports the power bank's output capabilities.
