Frequently Asked Questions (FAQ)

? Is the power bank compatible with all phones?

Compatible Devices:

• iPhone 12 and newer (with MagSafe and wireless charging)
• Phones with Qi wireless charging support (e.g., selected Samsung models)

? Can the power bank be charged using a cable type other than USB-C?

✓ The power bank only has a USB-C port for charging, so a USB-C cable is required.

? Why is my phone not charging?

✓ Check the phone's alignment on the MagSafe surface. Ensure the power bank is not depleted.

? Does the power bank get warm during charging?

   Explanation: Magnetic alignment is incorrect, or the phone is not compatible.
   Solution: Check alignment and compatibility. Ensure the power bank is not depleted.
2. Phone charging slowly
   Explanation: Wireless charging has lower power output. Two devices might be connected simultaneously.
   Solution: Charge via cable for higher power and/or disconnect other devices.
3. Power bank not turning on
   Explanation: The power bank is completely depleted.
   Solution: Connect the power bank to a charger and let it charge for a few minutes before trying to turn it on.
4. Power bank gets warm during charging
