Also, a tip I happened to see the other day. I found I had been making good emergency tinder for many years now. Clothes dryer lint.
Do they make wood burning cell phones?
Mine has that little trapezoidal port that the phone end plugs into. And the other end plugs into a 110 outlet. I've seen chargers for it that plug into a cigarette lighter. I have a 110 outlet in my new Jeep, but for my truck I'd need the 12 volt cigarette lighter deal. I have no idea what voltage or amperage the phone requires to run.
I've noticed that it varies by device manufacturer as to whether the charging cord is one with the wall plug attached or a USB plug with a wall adapter.
