How do I charge newer iPad model with a usb c to usb a cable

If you have an appropriate charger then can receive the cable, sure.

The iPad fifth generation has a USB-C port for charging and data transfer.

If your charger has a USB-A port you can use a USB-C to USB-A cable to charge it.

Yes, you can use a certified USB Type-A to USB-C charging/data cable - however, your iPad will only reliably charge when connected to a USB power source of 12W (2.4A @5V) or greater. 5W Power Adapters intended for older models of iPhone are inadequate to charge an iPad; if the iPad charges at all, charging will be very slow.

Be aware that many computer USB ports cannot source sufficient power to charge an iPad. Unless explicitly designed for charging connected devices, computer USB ports are typically limited to 0.5-1A @5V (i.e., 2.5-5.0W).

sure unless the cable is defect
