Julio Voltio (born as Julio Irving Ramos Filomeno on June 11, 1977, in Santurce, Puerto Rico) is one of the reggaetón genre's best-known artists.
His nickname came to be as the result of an accident. Before joining Karel, he worked as an electrician. One day, he stuck his hand in the wrong place and got shocked. Everyone then called him "Bombillo" (Light Bulb) and "Corto Circuito" (Short Circuit), until eventually giving him a nickname that stuck: "Voltio" (Spanish word for volt).
Growing up in the Parque Ecuestre section of Carolina, Voltio entered the music business as a teenager. Together with Rey 29 and Héctor Delgado (AKA Hector "El Father"), he formed The Masters of Funk. Although the trio released no listed albums, they were influential in starting the reggaeton movement.
Shortly after separating from The Masters of Funk, Voltio partnered with Karel, a neighborhood friend, to form Karel y Voltio. They released their debut album Los Dueños del Estilo in 2003. The album languished, however, and the duo's enthusiasm dwindled. Karel was last featured in La Mision 4. With few options, Voltio was preparing to exit the music business when Tego Calderón, a leading artist with White Lion Records, convinced him to sign with the label. Having taken Tego's advice, Voltio released the album Voltage AC, with the hits "Bumper", "No Amarres Fuego" (featuring Zion & Lennox) and "Julito Maraña".
Voltio is the eponymous second studio album by Puerto Rican reggaeton performer Voltio, released on December 27, 2005, by Sony BMG and White Lion.
Released roughly a year after his first solo album Voltage AC, Voltio charted and sold well, partly due to the successful single "Chulin Culin Chunfly", a collaboration with famous reggaeton performer Residente of Calle 13. It sold 4,020 copies in its first week, debuting at number twenty on the Billboard Latin Albums chart.
