I have these devices that use USB C to charge:

- Gaming Headphones
- Bose QC 45 noise cancelling headphones
- Baby sound machine
- MacBook laptop

Of the 4 devices, only the MacBook laptop can use a USB C wall outlet power adapter (I use the official Apple power adapter).

**This is the power adapter I am trying to use to charge the headphones and the baby sound machine (with a USB C to USB C cable), but it does not work:**

**The headphones and sound machine only charge if I use a USB-A (for the wall outlet) to USB-C cable (pictured below) - why?**

Is it not possible to charge these devices with a USB C to USB C cable? I just bought brand new Anker cables, so I know they cannot all be defective.
