    Abstract: An electrical port device having an electrical port and a cap or cover removable connected to the electrical port having a plug. A Y-shaped electrical cord or cable connects the electrical port to a pair of electrical receptacles. The Y-shaped electrical cord can include one electrical cord or cable section connected to the electrical port, a pair of electrical cord or cable sections connected to the pair of electrical receptacles, and a Y-shaped connector connecting the one electrical cord or cable section and the pair of electrical cord or cable sections. Further, the cap or cover and the electrical port have cooperating sealing surfaces to ensure watertight or waterproof sealing when the cap or cover is installed “on” the electrical port to prevent water or moisture reaching the plug.

    Abstract: An electrical port device having an electrical port and a cap or cover removable connected to the electrical port having a plug. An electrical cord or cable or cable section connects the electrical port to an electrical cord or cable or cable connector or splitter into a pair of electrical cord or cable or cable sections each provided with an electrical receptacle. Further, the cap or cover and the electrical port have cooperating sealing surfaces to ensure a tight waterproof sealing when the cap or cover is installed on the electrical port to prevent water or moisture reaching the plug.

    Abstract: A handheld device for jump starting a vehicle engine includes a rechargeable lithium ion battery pack (32) and a microcontroller (1). The lithium ion battery is coupled to a power output port of the device through a power switch circuit (15) actuated by the microcontroller. A vehicle battery isolation sensor (12) connected in circuit with positive and negative polarity outputs detects the presence of a vehicle battery (72) connected between the positive and negative polarity outputs. A reverse polarity sensor (10) connected in circuit with the positive and negative polarity outputs detects the polarity of a vehicle battery connected between the positive and negative polarity outputs, such that the microcontroller will enable power to be delivered from the lithium ion power pack to the output port only when a good battery is connected to the output port and only when the battery is connected with proper polarity of positive and negative terminals.
