Instead of a jump start from your car which can damage modern vehicles, you can use a jump pack. $45 shipped is cheap insurance for the good samaritan. Has reverse cable detection, no more arcs, sparks or blow car computers. Hook it up, turn it on wait for the red LED to turn yellow and crank away. Plugs into a standard ac power cable for recharge. Extra features: usb charge port, two 12 volt outlets, led work light that flashes or on solid. Totally happy with it.
