VOLTAGE RUSTLING? Glad that my laptop has a long-life battery, or I could be in big trouble.

And, to the pedants out there, yes, I know it should probably be “amperage rustling.”

UPDATE: A reader suggests “joule thief.”

ANOTHER UPDATE: Reader Doug Sundseth emails: “‘Joule thief’ is fine for fast-charge devices, but could I suggest ‘trickle-down erg-onomics’ for slow-charge devices?”

Ouch.
