Media Mention: WHNT News

A Madison man has invented something that protects mobile device users from malware and identity theft that can come in through a USB port.
Stuart McCafferty, President of ChargeDefense, and his team said he’s already received orders for the Juice Jack Defender from hundred of clients, including the White House.

A lot of the work and development happened in a small room in the basement of his home that he calls “the lab.”

Inside it, McCafferty and two others designed something that prevents the trouble that can come from charging a mobile device through a USB port.

“You don’t know what you’re connected to,” said McCafferty.

The Juice Jack Defender, regular and turbo, is a small gadget that comes in five different colors. Simply put, it blocks the transmission of data.

“Our device guarantees that there’s no opportunity for data exchange,” said McCafferty. “It’s a charge only.”
