The company’s CEO Carl Pei officially teased the design for the USB Type C cable that will charge the Nothing Phone (2) earlier this week. Ahead of the launch of its upcoming smartphone, the cable’s key features have also been revealed.

According to the company, the cable wasn’t easy to build, as more details were shared recently. Official notes state that the team behind it had developed over 20 design concepts, most of which were rejected by manufacturers due to their difficulty in production. Additionally, the brand said that the transparent cable took two years to design and develop, including the materials.

The iron shell body of Nothing Phone (2)’s charger is created using an industry-first molding technique. By annealing the material three times at more than 1,000 degrees, the company was able to stretch the material four times. Using this method, we were able to create a seamless design with no lines or surface defects. Electroless plating helps in keeping the surface scratch-free by pre-plating and sandblasting the shell.

In order to ensure resistance and durability, Nothing’s cable was subjected to over 25 tests. The cable was even teased for its ability to withstand bending more than 16,000 times, more than 60 percent higher than industry standards.
