Common questions about manuals, registration, and support for this brand.
Most power banks feature LED indicator lights. When all the lights are solid or the digital display shows 100%, the power bank is fully charged and ready to use.
Ensure you are using a high-quality, compatible charging cable and are plugged into the correct port. Some ports offer higher output (like 2.1A or USB-C PD) than others. Refer to your user manual to verify if your device and the power bank support fast charging.
This feature is known as pass-through charging. While some power bank models support it, many do not, and doing so on unsupported devices may degrade the battery lifespan or generate excess heat. Always check your instruction manual to see if pass-through charging is supported.
Many modern power banks turn on automatically when a device is plugged in. For others, you may need to press the external power button once to begin charging. Consult your model's manual for specific functions.
