The device attaches to the iPhone and extends its battery life using a 1500mAh battery and a top-of-the-line, built-in solar panel.

GSLO president and CEO Tyson Rohde said that filing an application with the US Patent Office will serve to protect the company’s intellectual property rights.

GSLO approved a sample batch of the solar-powered iPhone accessories earlier this month from the Chinese developer of the Volt, Xiamen Solar Electronics (XSE).

Last month, GSLO signed a distribution agreement with XSE that provides GoSolarUSA with the exclusive right to sell and distribute the Volt in North America.

GoSolarUSA is currently preparing the Volt for its North American market launch.

The Volt Solar Charger is a product of Xiamen Solar Electronics based in Xiamen, China.
