To charge your AirPods Pro case via USB-C, you will need a USB-C to Lightning cable. This cable should have a USB-C connector on one end and a Lightning connector on the other end.
First, locate the USB-C port on your AirPods Pro case. It is located on the bottom of the case, right next to the lid hinge. Insert the USB-C end of the cable into this port firmly, making sure it is securely connected.
Next, plug the other end of the cable (the Lightning connector) into a USB charger or port. This can be a wall adapter with a USB-C port, a USB-C port on your computer, or even a portable power bank with a USB-C output.
Once the cable is connected to a power source, your AirPods Pro case will begin charging. You can keep the lid of the case open or closed during charging, it won’t make a difference. The LED indicator light on the front of the case will show the charging status. It will turn amber when the case is charging and green when it is fully charged.
It is important to note that you can charge your AirPods Pro case with or without the AirPods inside. If the AirPods are inside the case while it is charging, they will also be charged simultaneously. This is convenient if you want to ensure that both your AirPods and the case are fully charged when you need to use them.
In summary, to charge your AirPods Pro case via USB-C, connect one end of a USB-C to Lightning cable to the USB-C port on the case, and the other end to a USB charger or port. The case can be charged with or without the AirPods inside, and the LED indicator on the case will show the charging status.
