Most of us do not feel the need of carrying around a jumper cable or a flash light for every trip we make feeling that they are not as essential as they are deemed to be.
But truth be told, you might never actually know on which particular trip you might feel the need for these very items that earlier you might have discarded without further thought.
Suppose, your car were to fail to start because of a dead battery and you are in the middle of nowhere, miles from the nearest help.
A simple inclusion of a jumper cable will not just help you recharge your batteries but will also save you the time required to push your car into the nearest garage.
