Phone Charger Locket

I am creating a locket that holds a phone charger and uses the power cord as the neck cord. It is a copper, octagonal box form with an internal piece that holds the plug head. The top surface of the box will be decorated by an enameled plate.

My concept is based on how our lives have been streamlined and simplified from the days of having multiple personal objects that were carried daily (ie pocket watch, cigarette case, lockets of loved ones, snuff boxes). These objects were often beautifully made and today hold a vintage appeal as collector items. My idea arose from the idea that today with cell phones, phone apps, decrease in tobacco use etc, we have decreased our number of personal effects and those items we do have tend to be cheaply mass produced. I am trying to create a conceptual art piece that combines that vintage aesthetic, namely of a snuff box, with something that is important and useful today.

I am now looking for feedback on my piece. I originally made a design using an Ipod as well but desided on the phone charger since Ipod cases already exist. Do you think that there is another object that could better express the concept of a modern necessity? Would the Ipod have been a better choice? Also is there a different vintage/antique object that could better demonstrate the difference between modern and antique?
