Senses of "entrust," "command," "accuse" all emerged in Middle English and were found in Old French. Sense of "rush in to attack" is 1560s, perhaps through earlier meaning "load a weapon" (1540s). Meaning "impose a burden of expense" is from mid-14c. Meaning "fill with electricity" is from 1748. Related: Charged; charging. Chargé d'affaires was borrowed from French, 1767, literally "(one) charged with affairs."

(as in take charge, late 14c.; in charge, 1510s), which progressed to "pecuniary burden, cost, burden of expense" (mid-15c.), and then to "price demanded for service or goods" (1510s). Legal sense of "accusation" is late 15c.; earlier "injunction, order" (late 14c.). Electrical sense is from 1767. Slang meaning "thrill, kick" (American English) is from 1951.
