# 26 Apr 2005, 10:24PM: Batteries It Is: The ugly little cubes that plug into a power outlet and recharge a phone or power a mobile cassette recorder or what have you have a special name. The hip call them "wall warts." Tonight I am upending the house in search of the wall wart for my tape recorder. Any wart supplying 3 volts of direct current would suffice. I found 4.5V, 15V, 3.7V, all sorts of mutually incompatible adapters instead. Standards, people!
