From Wikipedia:

Julio Voltio (born as Julio Ramos March 20, 1977, 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).
