7. Troubleshooting
- Power Bank Not Charging: Ensure you are using a certified USB-C charging block with at least 5V=1A (5W) output. Check the USB-C cable for damage and ensure it is securely connected.
- Device Not Charging Wirelessly:
- Ensure the power bank is sufficiently charged.
- Verify that your device is Mag-safe compatible or has a Mag-safe compatible case.
- Remove any foreign objects or thick cases that might interfere with the magnetic connection.
- If the blue light flashes 2 times per second, it indicates a foreign object between the charger and your phone. Remove any obstructions.
- Ensure the clear plastic shipping protection has been removed from the power bank.
- Slow Charging: Wired charging (22.5W) is faster than wireless charging (7.5W for iPhone). Ensure your device supports fast charging and that you are using a compatible cable. If using an energy-intensive app, charging speed may be reduced.
- Power Bank Overheating: While the power bank features NTC temperature control, some warmth during charging is normal. If it becomes excessively hot, disconnect it immediately and contact customer support.
- Power Button Functionality: For wired charging of other devices, press the side button once to turn it on. Double-click the button to turn it off. Wireless charging for iPhones typically starts automatically upon magnetic attachment.
