Would be killer if I were an electrical engineer, but sadly my ears are missing the engine.
This is an invention that allows users to literally cut the power cord connecting their electric devices and replace the pronged end with a 2-part charger/battery system.
Take your waffle iron to the beach!
The end of any power cord is removed and a clamp-on (no tools required) fob is attached in its place.
This fob connects to a rechargeable battery, just like wireless power drills.
20V should be sufficient, but can increase in ability as technology increases.
Bring your favorite lamp camping!
I realize there has to be some power conversion and modulation happening inside the device.
