In 2011, Voltage was released in New Zealand, but was given the name Electro Shock, and described as "DEW with a charge of wild berry flavor." It was commonly mistaken as a different flavor than Voltage, but the two were the same flavor. Electro Shock was discontinued in 2014 and replaced with White Out.
In 2013, the flavor was released to Circle K stores, and Circle K is currently the only convenience store chain that sells this flavor in fountain form and it still is today.

In other foreign releases, in August 2014, Mountain Dew Uganda announced that Voltage was released in Uganda.
In 2017, Mountain Dew Malaysia renamed their flavor Live Wire, as Voltage. The formula is still the same as Live Wire, and therefore looks and tastes nothing like the Voltage anywhere else. In the same year, Voltage was released in Honduras, but was given the name "Xtreme." It was described as "DEW Cargado de Frambuesa."
Voltage is a blue-raspberry flavored soda with added ginseng, and is bright blue in color.
