Ken Kawamoto's Power Struggle Game Uses USB-C Cable to Decide Which Phone Charges
Japanese developer Ken Kawamoto created a game where two smartphones linked by a USB-C cable tap their screens to win charging priority.
Japanese developer Ken Kawamoto has created Power Struggle, a game that connects two smartphones with a USB-C cable and turns charging into a competition. Players tap their screens to fight for charging priority.
The outcome is physical, not just on-screen: the winning phone actually charges, while the losing phone's battery drains. The game works by using USB Power Delivery's ability to swap power supply roles between connected devices.
There are no details yet on pricing, release date or which platforms will carry the game. According to etnews.com, the project is a single-developer effort by Kawamoto.
