6. Car Charger for Your Devices
All of the previously listed items can keep you alive, help you attract attention and make it possible to get your car back on the road. However, if you have a cellphone charger in your car and can get a signal, you will have a good opportunity to contact emergency services before the rest of these supplies will become imperative to save your life. Of course, you cannot rely solely on your cellphone because some areas have no reception, and you may also end up turning to your winter emergency car kit after a natural disaster or terrorist attack.
Gathering all of these supplies will dramatically improve your odds of surviving any type of winter emergency. Other items that you should consider adding to your kit include kitty litter to create traction and maps of your outlying area.
