Bad cables for USB-C to USB-A can actually damage the equipment they are plugged into.
Google Engineer Benson Leung has been testing USB type C to USB type A cables to find bad ones after discovering that the OnePlus USB-C cable could cause damage when used with other phones.
His latest test of a third party USB-C to USB-A cable left him with 2 broken USB PD Sniffer devices and a broken Chromebook Pixel laptop.
He has written a Google+ article about what the problem with some USB-C to USB-A cables are, and why they can be really dangerous to your equipment.
He has done a lot of reviews of USB-C to USB-A cables on Amazon.
So you should be very careful about what kind of third-party USB-C to USB-A cables you buy, and even try your best not to reuse cables for one phone brand with another at this point.
