Ever had a "Shake Flashlight" (Faraday Flashlight) go dead on you? They work on moving magnetic fields - so put the flashlight near to a transformer that is plugged in - right next to it! Maybe near a fan motor case while it is running.
The magnetic field emanating from a transformer or motor coil will charge the flashlight up very quickly, so don't leave it there for more than 10 minutes or so. Mine was dead and came back in 5 minutes sitting on top of an old electric train transformer (plugged in).

I am a bit confused. Why not just shake it because it would recharge in a lot less time and no need to worry about possibly overcharging via a transformer?
Mine were dead and it took what seemed at least ten minutes to shake them back to life! My arms got a good workout :) I'm eager to try this instead. Although I have about 50 flashlights already so don't reallly need these two and am now thinking about keeping the two that I have in the car and wonder if the movement of the car over rough roads would recharge them? Everytime I see a new type flashlight on the market (usually at Costco or BJ's), I buy!
