[Important Capacity Notice]

• The Nominal Total Capacity (e.g., 10000mAh) of a power bank's internal battery cell is measured at 3.7V.
• The standard charging voltage for devices like smartphones is 5V. During discharge, a voltage conversion and boost process occurs, which involves inevitable energy loss.
• Therefore, the Actual Effective Output Capacity of a power bank is approximately 60%-70% of its Nominal Total Capacity.
• Example: For a power bank with a nominal capacity of 10000mAh, its actual available capacity for charging devices is approximately 6000-7000mAh (specific value varies bydevice and usage environment).
