This $4,000 iPhone X has its own solar battery — and the first one will be mailed to Elon Musk

A Russian accessories maker called Caviar just released one of the most expensive iPhones you can buy.

The iPhone X Tesla is a customized iPhone X plated in carbon and gold with a built-in solar battery. The device starts at more than $4,000, and comes in its own wooden carrying case.

Caviar is known for making elaborate accessories that cost thousands of dollars. What makes the cases different is that they're not removable - Caviar adheres its designs directly to the device itself.

But the Tesla device - named because of Elon Musk's commitment to sustainable energy - is Caviar's first with its own solar battery.

Here's how it works.


The Caviar iPhone X Tesla isn't just a case — the iPhone X is included.

Rather than a standalone case, Caviar seemingly adhered the Tesla case directly to the phone.

It comes in two models: 64 GB and 256 GB, which cost about $4,064 and $4,847 respectively.


The Caviar iPhone X Tesla is equipped with a solar battery. The battery harnesses solar energy in order to charge up your phone.


Caviar says the battery can charge using either the sun or bright lamps.


The device has a carbon base, a solar battery charge indicator, and a shock-resistant solar panel.


The case seems to make the iPhone X considerably thicker, though. With the case on, the device is 16.2 mm — without a case, an iPhone X is only 7.7 mm.

The iPhone X Tesla case is so thick, the camera bump on the back of the phone becomes recessed inside the case.


Caviar says the case is inspired by Nikola Tesla, Steve Jobs, and Elon Musk.
