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: 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.
