POWER BANK APPARATUS FOR MEASURING CAPACITIES OF OTHER POWER BANKS

摘要

A power bank apparatus for measuring capacities of other power banks is provided. The power bank apparatus includes at least one input port, at least one detection circuit, and a processing circuit. The input port is configured to receive an input power signal from the other power bank as a capacity measuring signal. The detection circuit is connected to the input port to receive the capacity measuring signal. The detection circuit detects a voltage and a current of the capacity measuring signal to generate a voltage value and a current value. The processing circuit is connected to the detection circuit to receive the voltage value and the current value. The processing circuit calculates a power supply time according to the current value. The processing circuit calculates a capacity value of the other power bank according to the voltage value, the current value, and the power supply time.
