If your iPhone or iPad is not charging with the USB-C-to-Lightning MFi Charging Cable (ST-TCL10M), the cause is usually the connection at one end, the power adapter, or debris in the Lightning port. The USB-C-to-Lightning MFi Charging Cable is Apple MFi certified, and charging and data transfer start automatically once both ends are connected.

How to fix charging problems with the USB-C-to-Lightning MFi Charging Cable

1. Plug the USB-C end into a USB-C power adapter, a MacBook, or a USB-C hub, and the Lightning end into your iPhone or iPad.
2. Make sure both connectors are pushed all the way in. A Lightning connector that is slightly out will not start a charge.
3. Inspect both ends of the cable for visible damage, bent pins, or debris, and check the Lightning port on your device for lint.
4. Try a different USB-C power adapter or a different USB-C port.
5. Try a different wall outlet.
6. Test the cable with a different iPhone or iPad to confirm whether the issue is the cable or your device.
7. Charge the same device with a different cable to compare.
8. Restart your iPhone or iPad, then plug it back in.
9. Set the right expectation on fast charging. The cable supports fast charging on compatible iPhones when you pair it with a USB-C power adapter rated at 20W or higher, such as an Apple USB-C Power Adapter. A lower wattage adapter still charges, just at a standard rate.
10. If syncing is the problem rather than charging, connect the cable to a computer rather than a wall adapter. The cable supports data transfer at up to 480 Mbps, so it handles backups and file transfers between your device and your computer.

If the problem continues after these steps, submit a support request.
