Abstract: A Portable automotive battery jumper pack with detachable backup battery. The invention is configured to be user friendly with a flexible compact design. The invention will be used in the portable, automotive electronics area.

Abstract: A fast charging high energy storage capacitor system jump starter is described. The jump starter apparatus incorporates a method of using reserve energy from a depleted electrical system such as an automobile battery, combined with a fast charging high energy capacitor bank to enable the rapid and effective way to jump start a vehicle.

Abstract: A portable light includes a light stand having a longitudinal axis and a light assembly section attached to the light stand. The light assembly section is adapted to be connected to a power source and includes a support having a support axis being rotatable and linearly displaceable relative to the longitudinal axis of the light stand; a light panel holder tiltably attached to the support such that the light panel holder is tiltable relative to the support axis; and a light panel removably connected to the light panel holder and tiltable relative to the support axis. The light panel contains a rechargeable battery and a light selectively electrically connectable to at least one of the power source and the rechargeable battery when the light panel is connected with the light panel holder and being powered by the rechargeable battery when the light panel is removed from the light panel holder.

Abstract: A portable battery boost and jump starter apparatus for charging a vehicle battery is described. The apparatus can monitor and determine the existence of a fault condition in the vehicle battery and provide a battery boost or jump start depending on the level of depletion.

Abstract: An electrical outlet includes an outlet housing having an outer support arm and an inner support arm, the outer and inner support arms defining a socket receptacle; the inner and outer support arms having a rotational support member and a fixed electrical contact assembly; a rotary socket having at least one plug receiver for receiving an electrical plug and a rotary contact plate attached thereto; wherein the rotary contact plate is rotationally supported by the rotational support member, and the rotary contact plate maintains electrical contact with the fixed electrical contact assembly through a predetermined range of rotation of the rotary socket. Rotation control functions of the rotary contact plate to limit the range of rotation and provide adjustable angles of rotation are also described.

Abstract: A high efficiency battery charger. The high-efficiency battery charger can include a first transformer to produce a charging current, a second transformer to produce a maintenance current lower than the charging current, a power feed circuit having an input for connection to a power source, and control circuitry configured to detect a depleted battery to cause the power feed circuitry to feed power to the first transformer while disabling the second transformer, and to detect a charged battery to cause the power feed circuitry to feed power to the second transformer while disabling the first transformer.
