Hi, I can confirm this. I have a 12 inch ipad pro on latest ios (as of 29 dec 2017) and 87W charger and a 1m usb-c to lightning cable. Charging does not work.
The literature on the 87W power adapter says it only supports output combinations of 1) 20.2V@4.3A 2) 9V@3A 3) 5.2V@2.4A that is to say it does not output at 14.5V@2A which has been stated by Serenity as required for fast charging. Secondly, the usb-c to lightning cable does not even seem to ‘latch on’ (click sound) properly to the 87W adapter (whereas the usb-c to usb-c cable I got with the 87W adapter itself does attach properly)...so I think there’s a difference in the pin architecture/layout of the usb-c to lightning cable. So now I’ve separately ordered the 29W adapter. Will report back once I get it.

I use my 61W charger to charge my Air 2 and my Pro 12.9” and it works fine. I use it to fast charge my X as well. I wonder if it’s specific to the 87W charger

Thank you for letting us know!
Is it worth the price to fast charge the iPad and iPhone?

To me it’s worth it, especially when I’m leaving work in an hour and need to charge. That hour gets me up to like 90%

That’s a solid point

Is the 87W adapter recommended for the iPad Pro 12.9"? Everything I read until recently says that the Apple 29W USB-C Power Adapter is the correct one to use for quick charging the 12.9 along with the USB-C to Lightning connector, although neither come with the iPad. I don't have a Macbook.

I use the 29W Charging adapter with a USB-C to lightning cable and adapter with my iPad Pro 2, it charges without issue. I traded in my MBP for an iMac PRO so I no longer have the other charging adapter.

I have an 87W power brick for my MacBook Pro 15" and I've used it to fast charge my iPad Pro 12.9 2018. I believe it will only draw the power maximum that it needs and works great.
