The charger coming with the iPhone 7 could charge all my androids, including the Sony T1 and T3 I have. I have no idea what kind of cable it was, but I deliberately used the oldest microUSB cable I have, one that came AFAIR with a Nokia E71.
The charger also provided energy to USB-based lamps (for notepads and laptops), which IFIAK do not use signalling.
