Competitive smartphone charge transfer via USB-C

Smartphones can now exchange energy via USB-C in a game format. Two devices are connected by a cable, and users compete in tap speed.

The winner pulls the loser's charge to themselves. The project is available for self-build and testing.

• Using USB-C port for data and energy transfer
• Competition mechanics in the form of screen taps
• Redistribution of battery charge between devices

Developers presented the Power Struggle project, which turns routine charging into an exciting process. Players must actively interact with the interface to win the battle for energy.

The application source code is hosted on GitHub. Users can download the repository and test the technology on compatible devices.
