Once again, [Rulof]’s putting his considerable hacking abilities to good use, his good use that is. By modding a few simple parts he’s put together something that he can carry around on his keychain that’ll allow him to steal power from his friend’s phones to charge his own phone.
He starts by cutting away the motor from an iPhone fan to isolate the Micro USB connector. He then removes the charging circuit board from a cheap Chinese USB power bank, and solders wires from the Micro USB connector to one side of the board. Lastly, he cuts away the Lightning connector from a Lightning-to-USB cable and solders that connector to the other side of the circuit board. For longevity and cosmetics, he puts it all in a small wood block and connects a key ring. The result is a small, neat looking box with a Micro USB connector on one side and a Lightning connector on the other. You can see him make it, and then use it to steal power from his friends in the video after the break.
And as long as his friends don’t catch on, he’ll never be without a power source again. But if they do catch on, he could always turn an ATX computer power supply into an 8 USB port charging station and win his friends back by charging all their phones. And what if there just isn’t any power because you’re city’s been hit with a cyclone? For that, one very capable hacker has built a hand cranked phone charger.
