I'm not entirely sure. Many sigils which replace technology were developed before the technology came into being. I don't have a fridge, I have a coldroom whose temperature is regulated by magic. My intercom isn't a speaker system, it's a series of sigils which project my voice. Sigils are more analogous to the wiring inside a piece of eletrical technology than the batteries that power it.
It may be possible to develop something similar to what you're asking, but it would depend on what you're writing it into.
