Even though Jay-Z is a proud dad, that's not slowing him down from expanding his business portfolio. The rap mogul just inked a multi-year global pact with Duracell to become the face and voice of Duracell Powermat JV.

What is a Duracell Powermat JV? According to Engadget, it's a circular wireless charging mat with the ability to power up your smartphones, toys or any wireless device without using a plug-in cord. Duracell is planning to install these powermats at various locations including at Madison Square Garden, which will allow Knicks fans and concertgoers to charge their smartphones at any resting area or station. Isn't technology amazing?

Duracell teamed up with Powermat Technologies to create this unique product, which is still in its development stages. When considering a spokesperson for their product, they couldn't think of a more powerful figure than the king of hip-hop. "Jay-Z is power personified," beams Ran Poliakine, CEO of Powermat Technologies. "He inspires millions of people all over the world on a daily basis with his music and his story. There is no better face or voice that can move people to adopt a new paradigm in power delivery."

Jay-Z couldn't be happier to join Duracell in launching their new wireless technology. "I believe in the future of wireless energy and I believe that Duracell Powermat is the company to bring on the revolution," he said. "I'm partnering with Duracell Powermat because they're providing the solutions for the future."

Duracell is currently presenting its new line of wireless powering devices at the Consumer Electronics Show this week in Las Vegas.
