Abstract: A charging device includes a plurality of DC charging ports, a detecting circuit and a current output unit. The DC charging ports includes at least one first charging port and at least one second charging port. The output currents provided by the first charging port and the second charging port are lower than or equal to a first current limit and a second current limit, respectively. The detecting circuit is coupled to the DC charging ports to detect the output currents from the DC charging ports. When the current required by the first charging port is lower than the first current limit, the current output unit correspondingly supplies a requested current to the first charging port and distributes a surplus current to the second charging port. A total current limit of the DC charging ports is higher than a supply current limit.

Abstract: A power strip includes a power plug, an outlet block electrically connected thereto, and a light control module disposed inside the outlet block. The outlet block has at least one electrical socket and a luminous warning field. The light control module is for emitting a light to the luminous warning field in accordance with an output current of the electrical socket. The light control module defines at least two current ranges according to a rated current, where one of the current ranges is a safety current range, the upper limit of which is greater than 50% of the rated current. The light control module alters the light emitted to the luminous warning field in accordance with the correspondence between the output current and each of the current ranges, so as to make the luminousness of the luminous warning field to change in accordance with the output current.

Abstract: The present invention discloses a power strip including a plurality of power sockets and at least one USB port. The power strip includes a high-voltage side circuit and a low-voltage side circuit. The high-voltage side circuit includes a power input terminal, a plurality of AC output terminals, and a first power circuit. The low-voltage side circuit includes a DC output terminal, a second power circuit, and a control unit. Each AC output terminal is coupled with the power input terminal and one of the power sockets and at least one AC output terminal powers the corresponding power socket according to a control signal. The second power circuit senses the first DC power before generating and transmitting a corresponding second DC power to the USB port through the DC output terminal. The control unit powered by the second DC power is configured to generate the control signal.

Abstract: An uninterruptible power supply and a method of power saving thereof the uninterruptible power supply includes a switch and a backup power generator. The switch is coupled to a public power and a load, and backup power generator is coupled to the switch, the public power, and the load. Furthermore, the backup power generator is for controlling the switch and providing backup power for the load when the public power fails. Additionally, the backup power generator stops working in response to a trigger signal outputted from the load while the load is disabled.
