I did a search and couldn’t see it. Is there any issue with charging my iPad Pro 11 inch with the 61W charging brick that came with my MacBook? I’m assuming something internally regulates, but wanted to confirm there is no issue doing this.
 
There’s no problem with fast charging. But understand that fast charging does degrade battery life and long term health.
 
You be fine. I use the 85-watt charger to charge all iPhones and iPad Pros. Quick charge too!!!
 
Good to know, thanks guys. I don’t care about the fast charging as much as I didn’t want to add another cable to my work area if I didn’t need to.
 
As I have already written in another thread here. If you want to charge as fast as possible you need a brick that supports Power Delivery with 15V, because the new iPad Pros can handle max 45W (15V/3A) in theory. In practice it‘s less then 40W.

Apple offers several Power Adapter for this:

- Apple 30W USB-C Power Adapter 30W (20V/1,5 A PD), 30W (15V/2A PD), 15W (5,V/3A) / this one replaced the 29W brick which supports (14,5V/2A PD) 12,48W (5,2V/2,4A)

- Apple 61W USB-C Power Adapter A1947 (13” MacBook Pro 2018) 60,3W (20,3V/3A PD), 45W (15V/3A PD), 27W (9V/3A PD), 15,6W (5,2V/3A)

The following two adapters are not supporting 15V. So, they should charge slower than the ‘15V Adapters’. But the new iPad Pro should also take advantage of the 9V/3A from this two adapters and also charge faster than the original 18W iPad power brick:

- Apple 61W USB-C Power Adapter A1718 60,3W (20,3V/3A PD), 27W (9V/3A PD), 12,48W (5,2V/2,4A)

- Apple 87W USB-C Power Adapter 86,86W (20,2V/4,3A PD), 27W (9V/3A PD), 12,48W (5,2V/2,4A)

That actually does sound like a problem.

Nope! “Like other modern mobile devices, there’s no danger to using a USB-C mains adapter rated at a higher wattage — the IPad will draw as much current as they can handle, and no more. It won’t make your device hotter, worsen the battery’s longevity or cause a explosion.” Apple itself recommends the 30W USB-C Power Adapter on its website for the iPad Pros. It’s just about the price.

I have been using my 87-watt MacBook Pro power adapter with USB-C to lightning cable to charge my old 10.5" iPad Pro and never have I had any issues. I plan to use it for the new 11" one as well.
 
I have charged my 11" iPad Pro with my MBPtb charger since I got the iPad. I have no idea about speed as it has been during the night, but it charges fine and isn't crazy hot or anything during the charge.
