They could sell as an add-on a jacket with a generator driven by a stirling engine using body heat.  They could call it "McGyver 3DS Everlasting Power Source".   

The only problems with this is that the regenerative heat exchanger needed and the royalties for the McGyver name would result in making the device a bit too expensive...
