Blake Fuller combined what he experienced racing IndyCars with his business and engineering know-how to develop Go Puck Power, a lightweight and portable way to charge phones and tablets on the go.

The rechargeable battery system, which retails at $59, can hold up to five USB-powered devices at once without connecting to a wall charger. Fuller’s product, which can fit into a hand or pocket, gained the attention of Florida’s Universal Studios in 2015. Go Puck chargers now can be rented out by guests at the Orlando theme park, for $12.50 for a half day or $25 for a full day.

“That’s a huge win for us,” he says.

Before Go Puck, Fuller, 36, produced a patented lithium-ion battery for race cars through his former company, Braille Battery, which he began in 2001. In 2014, Braille Battery, a multimillion-dollar business, was acquired by Ottawa-based Grafoid Inc.

“[With Braille Battery], we learned to challenge the status quo, and produced something that was deliverable on time and that exceeded expectations with no compromise toward reliability,” Fuller says.

Fuller’s 6-year-old company now has 21 Sarasota employees in research, marketing and administration; manufacturing is in China. He would not disclose sales figures, but plans to increase revenue by 1,000 percent within three years. More immediately, he’d like to have between 500,000 and 1 million touch points—purchases, rentals or opportunities to utilize the product—by the end of 2016.

“Everybody needs one, everybody can afford one; it’s just about raising awareness,” says Fuller, who graduated from State College of Florida Manatee-Sarasota in 1998 with a business management and marketing degree.
