I have a macbook 12" (early 2015) and am using the USB-C multiport which works fine for USB-A devices, but won't charge my macbook from the regular USB-C cable (power source and cable both work fine). Is my multiport defective?

Hello Kamikatsu,

Thank you for posting in the Apple Support Communities. We're sorry to see that you're experiencing this issue, and we're here for you.

If the power cable and outlet work OK, then it might be an issue with the multiport adapter. One way to isolate the issue further is to try charging another Mac computer using the multiport. If more than one device won't charge, then the multiport could be experiencing an issue.

If you don't have access to another Mac, we recommend checking a few more things such as the cabling and updates. You can also reset the SMC which manages power. These steps and more are found in the articles below:

We hope this information is useful. Kind regards.

Kamikatsu,

Thanks for getting back in touch with us with the result. We’re happy to see that things are working again. 

Have a great day.
