Am I able to charge Iphone 13 pro using a 61w power adapter? or that will damage the battery ?

Once again, iPhone will absorb as much as the controller allows. iPhone 13 Pro Max can reach speeds of up to 27W when using a 30W or higher charger according to the reports online, however Apple recommends connecting all of the iPhone 13 models to their 20W charger.

Charging a device with a higher W rate will always affect the battery, because the higher the W – the higher heat generation will be and heat is bad for Li-Ion batteries. However, iOS is smart and the controller will limit the amount of power it is absorbing and will stop charging if the battery heats up way too much.
