Although the iPhone X is currently Apple’s most high-end smartphone option, users looking to customize their device can opt for a luxurious new look from Caviar.

The Russian luxury customization brand already introduced its mink-fur iteration of the iPhone X, but now the company has debuted its more functional take on iPhone X luxury styling. The new special-edition smartphone option from Caviar boasts solar panels built into the back of the device.

In addition to powering up the phone when exposed to sunlight or electric lamps, the panels just plain look cool. The design was inspired by revolutionary innovators Nikola Tesla, Elon Musk, and Steve Jobs.

Chic and minimalist with a titanium case and gold trim, the Caviar iPhone X Tesla is available starting at $4,500. All luxury styling aside, not having to worry about a dead battery alone could make the steeper price worth the investment.
