There is such a thing as killing a motherboard by charging "stuff" via the USB. Better hasten to your local alleged Genius store, go ask the clones there about it.
Yonny-Timmy are not morons so that one USB port is prolly heavy duty and can handle even two devices charging.....
Just buy a high quality-heavy duty>>>> USB splitter/multi port/what have you
Agreed. I think too many people are dismissing the single-port Macbook without considering what it offers. It's USB-C, offering much greater speed than older types of connections, with power to spare. A lot of power and speed. Think about the difference between USB 1 and USB 2 and USB 3.0. Now Apple is the first to offer USB-C which smokes all the other connection types. Make sure whatever USB hub you attach can handle all the devices you connect, because the Macbook can deliver all the power you will probably want for multiple devices (although battery life will be diminished from the available 9 hours or so).
