Portable Phone Charger
Portable phone chargers are handy to have when you have no other power source to charge your potentially life-saving method of communication. If your phone battery is dead from too much snow-covered-mountain picture-taking, and your car battery is dead because, of course, it is, a portable charger might just save you.
Consider purchasing a dedicated “car emergency” charger and committing yourself to leaving it in the car.
