A jumper cable is provided that includes: a first charging transfer cable having first and second opposing ends; a second charging transfer cable having third and fourth opposing ends, and a connecting element at each of the first, second, third, and fourth opposing ends, the connecting element configured to releasably attach respective ends of the first and second charging cables to one or more battery terminals. A portion of the first charging transfer cable is coupled to the second charging transfer cables between a first point of union and a second point of union, and the unequal length portions of the first and second charging transfer cables extend from at least one of the first and second points of union.

A clip assembly for attaching an electrical lead to a medical electrode. The clip assembly has opposing jaws that can be selectively clipped onto a medical electrode. The jaws are opened and closed using handles. A receptacle is disposed in one handle for receiving the electrical lead. Within the receptacle, the electrical lead makes contact with a shaped conductor. The shaped conductor extends into a jaw and contacts the medical electrode. A clamp is integrated into the handle. The clamp is used to selectively press the electrical lead against the shaped conductor in the receptacle. The clamp can be manually tightened and loosened. As such, the electrical lead can be readily attached to, and disconnected from, the clip assembly as needed.

The present disclosure discloses a charging apparatus. The charging apparatus comprises a power source module, a main control circuit, a voltage booster circuit, an adjusting circuit, and an output port. The charging apparatus is configured to charge a vehicle battery or other consumers through the output port. The power source module is electrically connected to the main control circuit and the voltage booster circuit. The main control circuit is electrically connected to the adjusting circuit and the voltage booster circuit.

Accessories are removably received by a non-contact electrical detector for measuring an electrical characteristic without galvanic contact between the accessory and a non-contact sensor in the non-contact electrical detector. In some embodiments, an accessory is positioned in a gap between first and second extensions of the non-contact electrical detector. In some embodiments, an accessory includes first and second recesses on opposite sides of the accessory. First and second clamp arms of a non-contact electrical detector are inserted within the first and second recesses to removably hold the accessory. An external conductive prong of the accessory is electrically coupled, or is selectively electrically coupleable, with an internal conductive prong of the accessory. The external conductive prong is configured to be inserted into a receptacle of an electrical outlet. In use, the accessory positions the internal conductive prong within a sensing area of the non-contact electrical sensor of the non-contact electrical detector.

A clamp for providing an electrical connection to a battery includes a first arm, a second arm, a joint member, a first pivotable connection, and a second pivotable connection. The first arm includes a proximal end, a distal end, and an electrically conductive member at the distal end. The second arm includes a proximal end and a distal end. The first pivotable connection is between the joint member and the first arm, and defines a first axis, about which the first arm rotates relative to the joint member. The second pivotable connection is between the joint member and the second arm, and defines a second axis, about which the second arm rotates relative to the joint member. The first and second axes are displaced from each other in a direction that is perpendicular to the first axis.
