The way to say power hour in Spanish is, Poder horas.

Power our is an event where people drink alcohol.  Usually people drink the most amount of alcohol within 1 hour.  In some cases, people drink one beer every minute for one hour, or sometimes 21 beer within 1 hour.  Often, power our happens on a person’s 21st birthday which is the time when they reach the legal drinking age.  Because people drink so much alcohol, they become extremely drunk very quickly.  There is a DVD game that is called power hour, and a musician also released a CD called power hour which resulted in a lawsuit.  In the end, there were no trademark infringements because the phrase is a generic term for a drinking game.
