A power device and a method for visualizing information thereof are provided. The power device is configured to provide operation power to at least one load. The power device comprises a display interface and a control circuit. The control circuit is configured to display a color icon by the display interface, so as to show at least one of a system status and a system setting of the power device by the color icon.

An adapter module including an adapter and a power cord is provided. The adapter includes a first interface, at least a second interface coupled with at least a load, an identifying circuit having a sensing switch configured at the first interface, a controller, and a detecting circuit. The first interface is provided for inserting by a connector of the power cord. The sensing switch changes its on/off state depending on whether the first connector provides a trigger. A first message is generated if the first connector provides the trigger. The controller is coupled to the identifying circuit and receives the first message. The detecting circuit is coupled between the first interface and the second interface for detecting a power parameter value, and provides a second message to the controller. The controller sends a warning message according to the first message and the second message.

An uninterruptible power supply (UPS) system with energy feedback to chargers and sinusoidal output charges a battery pack through a first charger under a mains mode. Under a battery mode, the UPS boosts DC voltage outputted from the battery pack to a higher voltage level through a DC-to-DC conversion module, converts the DC voltage to a sinusoidal AC voltage through a DC-to-AC conversion module, and supplies the sinusoidal AC voltage to a load. When the load has energy storage elements and discharged energy occurs in a power supply loop, a micro-controller unit can control the discharged power to charge the battery pack through a second charger, thereby solving the issue of the discharged power from the energy storage elements of the load and enhancing the operational efficiency of the UPS.
