Apple Type-C Cable — with USB-C connectors on both ends — is ideal for charging, syncing, and transferring data between USB-C devices. Pair the USB-C Charge Cable with a compatible USB-C power adapter to conveniently charge your devices from a wall outlet and take advantage of fast-charging capabilities. USB-C Power Adapters sold separately.
Some non-compliant cables simply won’t offer the full data speeds they promise. Others can’t be used for data at all. And yet others can draw too much power, which can not only damage any device you’re charging it with, but could even damage the USB port in your MacBook.
That latter problem is specific to older MacBooks, with a USB-A port. Those were designed with a maximum current draw as part of the spec. USB-C devices can draw significantly more power, so if you use a USB-A port to charge a USB-C device, then a non-compliant cable can draw more power than the port is designed to handle. That can damage both the device you’re charging and your MacBook. A compliant cable has a resistor to limit the current draw
