A universal adapter includes: a casing combinable with a front cover and a rear cover having a pair of outlet sockets formed in the rear cover to output power, a first plug having a pair of rectangular-shaped pins slidably held in an upper chamber in the casing and operatively pushed or pulled by a pair of first seesaw buttons pivotally secured on two opposite sides of the first plug for a convenient extending or retraction of the first plug, whereby upon extending of the first plug, a rectangular-shaped pin of "grounding pin" will be simultaneously biased for its forward extending to form triple rectangular-shaped pins for connecting municipal power such as in England or Africa to be output through the pair of outlet sockets in the rear cover; a second plug having a pair of flat blades slidably held in a lower chamber in the casing and operatively pushed or pulled by a pair of second seesaw buttons for a convenient extension or retraction for connecting municipal power to the two outlet sockets; and a third plug having a pair of round pins pivotally mounted on the front cover to be horizontally extended for power connection use and vertically received into the front cover when not in use.
