Is it safe to use a 29w USB-C power adapter to charge my 2017 iPad Pro 12.9"?

I keep getting conflicting information about this. Is it safe to use a 29w USB-C power adapter to charge my 2017 iPad Pro 12.9"?

I know it works, but I was also told by two different Apple support techs on separate occasions to only use the supplied 12w adapter, and that using the 29w adapter will degrade the battery faster, and that its not recommended to use with an iPad or iPhone. This confuses me when so many third-party websites and videos recommend using the 29w adapter for the much faster charge.

In addition, I have looked through some Apple support docs about charging the iPad, and none of them mention using the 29w adapter to get quicker charge. Also, the 29w adapter isn't even listed for sale in the iPad accessories/Power & Cables category of the Apple Store, only the 12w adapter.

Will the 29w power adapter degrade my iPad battery faster, or damage it in any way?

This is the info they have on their site

It lists compatibility with the 29W adapters

FYI,

It’s neatly $80 for the Apple 29 W Power/transformer block and the USB-C to Lightning Cable.

You will only save between an 1-1/2 to 2 hours of charge time.

IMO, kinda expensive just to save a couple of hours of charging time.

Some 12.9 iPad Pro users have reported that this higher wattage faster charging did not shave off that much time.

Your iPad will still take between 3-1/2 to 4 hours to charge.

You need to really weigh the benefit of saving up to 2 hours of charge time versus cost with this.

Good Luck to You!

This definitely clears it up for me. Thanks for providing that doc. I'm going to buy a 29w adapter for sure. The 12w adapter just takes too long to charge, especially while using the iPad.
