You could say John Borofka has put a handle on power.
He founded Poros, a company that designs travel and accessories bags with built-in battery system to charge your devices. The company’s fourth bag is a stylish backpack called the Tetra.
The Tetra carries a 10,000 mAh lithium ion battery, enough juice to fully charge a MacBook Retina or an iPhone 6s four and a half times. It can be ordered with a dedicated Apple Lightning Connector and is ready for the future with USB-C compatibility.
