A battery charging cable can be connected to a power supplying device and supply electricity to, and thereby charge, the battery of another device when the battery is low in power. The battery charging cable includes a USB Type-C connector at one end and a positive-electrode clamp and a negative-electrode clamp at the other end, wherein the clamps can be respectively clamped to the positive and negative electrodes of the battery of a device to be charged. With the battery charging cable supporting a USB Power Delivery protocol, and the USB Type-C connector configured to provide a relatively high voltage and power, the battery charging cable provides overload protection and has great power transmission performance.

A clamp for a male terminal having features for preventing incorrect clamping, which comprises a main body having a ring and two jaws, that are movable toward each other for the ring to hold the terminal. An engagement element is movable in the vertical direction and to act upon the jaws to move them toward each other. A clamping member, operable to move the engagement element comprises a stem and a nut. The stem is fixed to a base body, which is pivotable relative to the main body between a first position, in which the stem is inclined with respect to the vertical and a second position, in which the stem extends in the vertical direction. In the first position, the engagement element prevents the nut from engaging a threaded portion of the stem. In the second position, the threaded portion is adapted to be engaged by the nut.

A jumper cable clamp having a spring which urges the clamp handles in an open position and a locking mechanism on the handles to maintain the handles in a closed position. An electrical wire connector is connected to a distal end of one of the handles, which can be formed from an electrically nonconductive material.

A quick change battery clamp includes a first clamp body, a second clamp body, and a handle assembly. The second clamp body is coupled to the first clamp body. The handle assembly is selectively disposed through each of the first clamp body and the second clamp body. Each of the first clamp body and the second clamp body define an aperture having a substantially polygonal cross-section configured to receive a battery post. Each of the first clamp body and the second clamp body have an internal wall with a plurality of ridges configured to selectively abut the battery post. The first clamp body and the second clamp body are hingedly connected.
