NEW YORK (TheStreet) -- Energous  (WATT) surged 76.33% to $10.58 at the close of trading on Friday, the tech company's first day of trading after its IPO.

The company priced its initial public offering at $6 a share and sold 4 million shares. Energous also included a 45-day option for underwriters to buy up to an additional 600,000 shares. If this happens, then gross proceeds from the IPO would total $27.6 million.

Energous is developing WattUp, a wire-free charging technology that would allow users to freely walk around with and use their mobile devices rather than have to leave them on a pad or other station to charge.

More than 1.85 million shares changed hands on Friday.
