Mobile power and power information display method

The invention relates to a mobile power and a power information display method and belongs to the technical field of electronic circuit. The mobile power includes a battery module and a coulombmeter chip. The battery module is provided with batteries, and the voltage output end of the battery module is used to output voltage. The coulombmeter chip is used for sampling voltage output at the voltage output end, obtaining electric quantity information of the batteries according to the obtained first sampling voltage and sending the electric quantity information to an electronic device through a power connection line, wherein the electric quantity information is use for triggering the electronic device to display the electric quantity information. The mobile power and the power information display method can solve the problem of the mobile powers of incapability in displaying the electric quantity information when recharging the electronic device, and achieves the effect of timely displaying the electric quantity of the mobile power when recharging the electronic device.
