Need power? Anker to the rescue! 20,100 mAh beast that can charge at least 4 devices at once. As you can see, my Nexus 6P, DP-X1 and Mojo are all charging. What a power bank! It even has a Type C port to charge it or to charge compatible devices, too. The USB ports are rated 3A and the Type C is something ridiculous like 5A. Highly recommended.
The coloured cable is a cheap one from ebay that comes with 2X micro USB, 1 mini USB, 1 Type C and some silly iphone plug. It won't take more than two devices per plug as Mojo and DP-X1 would draw too much, but with another splitter my B&O Beoplay A1 Bluetooth speaker could be charging, too. Simply ridiculous.
