You can use your iPhone to charge your AirPods, Apple Watch, or another small device that supports USB Power Delivery at up to 4.5 watts. The Apple iPhone 15 model’s USB-C port allows the phone to charge AirPods or an Apple Watch directly.

If your AirPods or Apple Watch runs out of battery while you don't have access to a charger, you can just use your iPhone’s battery to power these devices.

Interestingly, this also extends to another iPhone 15. If two iPhone 15 devices are plugged into each other, the devices will communicate and determine which ‌‌iPhone‌‌ has the lower battery, and transfer power that way.

How to Charge AirPods and Small Devices

There’s no magic on how to achieve this. It is pretty straightforward and simple. All you need for this is a USB-C cable, no extra configuration is needed in your device. To charge a device with a lightening connector, just get the USB-C to lightening connector cable.

All you have to do now is connect the device to your iPhone with the provided cable. You can charge your Apple Watch by connecting an Apple Watch Magnetic Fast Charger to a USB-C Cable directly to your iPhone. You can also connect a Magnetic Charging Cable to your iPhone with the Apple USB-C to USB Adapter.

That’s all, no hassle, simple and straightforward.


This feature introduced by the iPhone 15 is great for emergencies. Now users need not worry about running out of power on smaller devices, as the iPhone 15 USB-C feature can be readily leveraged.
