Hello! Does anyone know if it's bad to use an Apple 70W USB-C power adapter to charge an iPhone 14? On Apple's official website it says that this adapter is compatible with all iPhone 15s, but it doesn't mention anything about previous devices and I'm afraid of damaging my battery.
Thank you very much for your help
iPhone 7, iOS 13
It's fine. The phone itself determines the power it needs to charge. You can use the 70W charger, but it won't charge your iPhone any faster than a 20W charger. Still, it won't hurt the phone in any way.

If you want the official answer, check with Apple Support.
Yes, 70W (5V3A, 9V3A, 15V3A, 20V3.4A, PD3.0 DCP) will work with iPhone 14, and will fast-charge.
I’d expect iPhone 14 to draw about 25W from this particular charger.
Under full prolonged output load, the charger will approach 60℃.

It won't harm it.
The following site mentions both the iPhone 15 and previous devices. See below from Fast charge your iPhone - Apple Support
To fast charge, you need an iPhone 15 model with a USB-C cable like the one that came in the box or an earlier iPhone model with a USB-C to Lightning cable and one of these adapters:
