Power adapters from old iPhone models, USB-A, can charge the iPhone 15 battery, but you will need a USB-C power cable. In addition, adapters from the old iPhone models develop only a power of maximum 5 watts (old models with a lower capacity battery), which means that charging can take four or five hours to reach zero to 100%. It's a very slow load.
So, if iPhone 15 is slowly charging, you will need a higher power load adapter. The USB-C port of the iPhone can theoretically receive energy at up to 27 watts, but there is practically a decrease in loading speed of up to about 20 watts. So, with a USB-C cable and a 20W USB-C USB-C power adapter, you can charge the iPhone 15 battery to 50% in about 30 minutes, and from zero to 100% in less than 2 hours. A quick load.
If you are the owner of a MacBook, you can use both the power adapter and the USB-C cable to quickly charge the iPhone 15 or iPhone 15 Pro battery. It is not a problem if the power of the charger is greater than the iPhone supports.
