Power bank capacity: Why 10,000mAh isn't always 10,000mAh

By PulseAugur Editorial · [1 sources] ·

Power banks advertised with a 10,000mAh capacity often do not deliver this full amount in practice. This discrepancy is due to energy loss during the voltage conversion process from the power bank's internal 3.7V to the 5V required by USB charging standards. Additionally, the charging circuitry within the mobile device itself also consumes some power, further reducing the usable capacity delivered to the phone's battery. AI
