Sometimes I’m at the doctor’s office, at the library, or even at the grocery store and see an unused power outlet. My phone is dying. I feel weird plugging in, but I feel even weirder asking for permission.

    A 2000 mAh battery that is charging at 3.7V for one hour per day uses 2.5kWh of energy per year. About $.50 at ~$.20/kWh. That’s pretty remarkable!
