Recharging Our Phones Using Only Brute Strength

Summary
Mark and Ethan compete against each other to see who can power up their phone first with a hand-cranked electric generator. The loser of the match was required to fully charge their phone using only this method. After some time, Ethan's briefly powers up, but before he could claim victory, Mark jokingly accuses him of cheating and changes the end goal to charging their batteries to 5%. Some time after, Mark's crank breaks off due to his excessive force. Feeling disgruntled, Fischbach replaces his rotating mechanism with a power drill to accelerate its revolution. Although his phone briefly turns on in the background, Mark never notices, as the device overheats from the drill's immense speed and discharges electricity, which breaks his generator.

Trivia

 * The devices used in the video can easily generate enough electricity to power up their phones. The issue lies with time, requiring a prolonged period to properly charge a person's phone as they are only capable of receiving a few watts at any given moment.
