Portable vehicle battery jump start apparatus with safety protection and jumper cable device thereof

A jumper cable device for use with a jump starter having a power supply or battery and an output port for connecting with the jumper cable device, the jumper cable device comprising:

• a single plug having a uniform or substantially uniform width along a length of the plug, one end of the plug being configured to fit into the output port of the jump starter, the output port of the jump starter and plug of the jumper cable device providing a positive polarity electrical connection and a negative polarity electrical connection between the output port of the jump starter and the plug of the jumper cable device;
• and
• a pair of battery cables connected to the plug, the pair of battery cables having cable connectors for connecting the pair of battery cables to the battery being charged,
• wherein the plug is structured so that the plug will only fit into the output port of the jump starter in a single orientation to ensure a proper orientation of the positive polarity electrical connection and the negative polarity electrical connection between the output port of the jump starter and the plug of the jumper cable device.
