That's the point, you need an additional cable. I charge most of my stuff with my laptop cable: laptop, Smartphone, Ebook reader, portable speaker. Only my headphones are still in MicroUSB. As the laptop cable doesn't have an outgoing USB A/C port, I would have to carry an additional cable and charger if I had an iPhone.
