The USB-C cable that comes with a MacBook's power adapter is not charge-only but only supports USB 2.0 throughput for data [0]. I think that means it also can't be used for things like DisplayPort Alternate Mode. BTW, if you order an extra USB-C power adapter from Apple [1], it does not come with any cables, not USB-C, not AC for use between the brick and the wall. It only comes with the fold-out prongs (I don't know what non U.S. models are like) but thankfully they didn't change that connector type so if you have an AC cable from a MagSafe adapter, you can use it.
