Abstract: A lamp string wire clipper for joining two sets of wires of a lamp string together comprises a holder and a lamp seat. The holder is formed by a first portion and a second portion, the first portion includes three trenches, a pin and a convex portion, the second portion including three trenches, a pin hole and a convex portion. The lamp seat includes a through hole and a via hole. After assembling with a lamp, two electric wires connected with a lamp is inserted in the through hole, a set of trenches enclose the via hole so that the convex portions align with the hole opening, one end of one of the two electric wire passes through the through hole enclosing by the first trenches, a further electric wire passes through the through hole enclosed by the third trenches. The present invention can be used to join wires of a lamp string together to form a net-like configuration.

Abstract: A charging device includes a charging circuit having a power inlet and a power outlet which is preferably connected to the charging circuit by means of a cable. An adaptor which is adapted to electrically connect to a given external power source, such as a wall outlet or a cigarette lighter holder provided on the control panel of an automobile, has a connection portion for releasable connection with the power inlet of the charging circuit for supplying electricity from the power source to the charging circuit. The adaptor may be provided with a voltage transformer to allow the charging circuit to be used with external power source of different voltage outputs. A battery holder has a connection portion for releasable connection with the power outlet of the charging circuit to supply the output of the charging device to the battery holder.
