Best Apple wall charger for just purchased airpods pro?

Hi:

I want to purchase a wall charger for my just purchased airpods pro.

Is this the appropriate apple product? Apple 20W USB-C Power Adapter which will let me use the USB C to lightning cable packaged with the airpods pro.

Or would Apple's 19 Watt charger (I believe this i lightning to lightning).

Maybe an iphone charger which uses a lightning to lightning cable.

Apple tells me a charger with fewer Watts (they recommended 10W) would be best. The more Watts the faster the charge but the battery in the pods will be depleted more quickly.

Thanks in advance for your assistance!
