Battery capacity (10,000mAh): The rated capacity of the battery cell itself.
Rated capacity (5,300mAh / 5V⎓3A): This is the "effective capacity" that can actually charge a device.
When a mobile battery converts (boosts) the voltage to power a smartphone, some energy is lost. Therefore, please rest assured that the two different values ​​are displayed, as this is normal.

Yes, it is possible. The M10 is designed for multi-device compatibility and can be used in any combination of the following ways:

• MagSafe (wireless charging)
• Apple Watch charging pad
• USB-C (built-in cable or port)

Please note: When charging multiple devices simultaneously, the total output is limited to a maximum of 15W , so charging will be slower than when charging just one device .

• USB-C (single port): Maximum 35W PD input/output
• Magsafe (wireless): Max 15W
• Apple Watch Pad: Max 2.5W
• Simultaneous use of multiple ports: Total maximum 15W

Generally, yes. However, your case must be compatible with wireless charging and the magnets must be properly aligned. Charging may become unstable or stop if:

• The case is 3mm or thicker
• The case has a metal plate, magnetic card, metal stand, etc.
• The magnetic ring is out of position
• Samsung Ultra series (S24/S25/S26 Ultra, etc.): Due to the camera protrusion and device size, it may be difficult to align the magnet. In this case, we recommend using a USB-C cable for wired charging.

Yes, it supports "pass-through" which allows you to charge your smartphone while charging the device .

• We recommend using a PD-compatible fast charger.
• During pass-through charging, the device may become hotter than usual and charging speed may be slower. This is within the product specifications. If it feels too hot, remove it and let it cool down.

yes.
You can text and talk while wearing it.
However, the strength of the magnetic force (adsorption power) depends on whether your iPhone is MagSafe compatible or if you are using a MagSafe compatible case. The magnetic force may also be weakened by the material or thickness of the case, or by accessories (such as a card case or ring) attached to the back.

If you experience any issues, please try these basic checks first:

1. Change the cable: Try using another known-good USB-C cable and make sure it is firmly plugged in.
2. Change your charger: Try a PD adapter with a higher output.
3. Try a different device: Check if the issue is with your phone.
4. Allow to cool: If you have just used the device in a hot environment, wait until it has cooled before trying again.
5. Refresh: Repeating a full charge and full discharge may restore the battery level display to accuracy. If this does not improve the situation, please contact support with your order number.

This is a safety design feature of the M10. When multiple devices are connected, the total output is limited to 15W to optimize power distribution. If you need fast charging, please charge only one device at a time.

Yes, in principle it is possible.
Please make sure to pack your mobile battery in your carry-on luggage (not in checked luggage).
Most airlines allow lithium-ion batteries under 100Wh to be carried on board.
For details, please check the regulations of your airline (FAA, etc.).

For safety reasons, never use a power bank that has been submerged in water.
