Developer Ken Kawamoto has created a competitive mobile game called Power Struggle. The game requires two players to connect their smartphones using a dual USB-C cable to compete in a tapping speed challenge.
During the match, players must tap their screens as quickly as possible within a set time limit. The winner gains the ability to charge their device, while the loser's phone acts as the power source for the winner's battery.
Technical tests show the game operates with a current output of 1500 mA, resulting in a power output of approximately 7.5W at 5V. However, 1100 mA is consumed by the game itself, leaving only 400 mA for charging.
The effective charging power is limited to about 2W, making the game more of a novelty than a practical charging solution. The developer notes that the experience is intended for entertainment rather than utility.
