Abstract
A power device capable of displaying various statuses and a displaying method are provided. The power device includes: a central microprocessor, a power conversion circuit, an LED bar (or a light bar) circuit, and a battery pack. The central microprocessor intrinsically has color setting and control logic and is internally provided with a color setting and control logic circuit. The power device is externally connected to a utility power source, a solar photovoltaic power source, a backup battery pack, and a load. The color setting and control logic circuit enables the LED bar circuit to correspondingly emit LED light of at least two colors according to different power sources supplied to the load or a battery capacity, and the LED light is displayed in a breathing-like manner. The central microprocessor adjusts a breathing rate of the LED light according to a power consumption of the load.
