I am too cheap to purchase a USB charging connector for my iPhone, so I was wondering if there's a way to create a USB cable at home or use some other USB cable and get the job done safely.
For example will other USBs, assuming the connectors fit, charge, or no? I figure they would since they are just USB 2.0 based and iPhone can't tell the difference from its hardware perspective.
A better way to look at this: any other way to charge an iPhone without an iPhone-specific charger? I heard it's possible to use a wind turbine or dynamometer, but those are not inexpensive. Could those be replicated at home with typical at home tools? For example could I make a crank device that delivers powered-charge through the USB to the iPhone's battery?
