The new Apple MacBook has only one port: a single USB-C port. That’s an idiotically minimalist design, but that’s another discussion.
Two things you need to buy:
The PlugBug, $35 – this pops onto your power adapter and gives you a separate USB power plug good for simultaneously charging your USB devices. It was designed for the larger MacBook power supplies, so it hangs off the edge of these smaller USB-C ones, but whatever. Still works great.
USB to USB-C cable, $15 – lets you run or charge your MacBook off a USB battery charger, car charger, another laptop’s USB port, whatever. This charging method isn’t as fast as Apple’s power adapter, but in a pinch, it’s better than nothing.
Even after a couple of weeks of ownership, it’s still surreal plugging my laptop into a USB battery. That’s pretty awesome.
