Some Charging Accessories Not Working With iPad Pro Magic Keyboard
Some USB-C power adapters and cables appear to be unable to charge the iPad Pro through the Magic Keyboard, according to multiple complaints from MacRumors readers.

Several new Magic Keyboard owners have noticed that there are issues with the passthrough charging, which can refuse to charge when using a third-party cable or power adapter. From the forums:
Has anyone with the new MK experienced any issues in using the pass-through charging port?
I have tried three different USB-C cables and all result in 'Not Charging' being displayed next to the battery icon (See picture).
I have been on the phone to Apple Support for the last hour trying to explain this to them, it would appear to be a hardware issue and they are arranging collection of this one and dispatching a replacement upon receipt of the faulty unit.
MacRumors can confirm that we've been unable to charge the iPad Pro using Anker's PowerPort Atom and Apple's official USB-C cable. When attempting to charge through the Magic Keyboard's port using this accessory, the iPad refuses to charge and makes the charging sound every few seconds.
Other forum members have reported being unable to use Anker power adapters and charging cables, as well as charging cables from companies like Mophie.
Still other Magic Keyboard owners have had no issues with their third-party cables, so it appears to be an issue that's only affecting some power adapters and third-party cable options.
It's not clear if this is an issue on Apple's end or on the end of the hardware manufacturers who created the cables and power adapters, so more investigation will be needed to figure out what's going on. We've contacted Anker for more information and will update this article when we hear back.
Magic Keyboard owners who want to charge using the USB-C port on the accessory may need to purchase Apple's official charging cables and power adapters to ensure proper charging. At least one forum member was told by Apple's support staff that an Apple USB-C cable is required.

I used to see this indicator all the time when my iPad is plugged into a standard (not high power) USB port on a computer - one that is limited to 500 mA (2.5W). And I've found that if I'm running high-powered apps, the battery will discharge. If I'm not - if it's either idle or running a low-power function, like installing a software update - the battery does charge. It charges slowly, but it does charge, as indicated by the battery indicator shown by iTunes.
In other words, this indicator should only be seen as an indicator that the power brick isn't providing enough current to charge the battery and operate normally at the same time, not that it isn't charging at all.
Then again, I wouldn't be surprised at all if Apple never tested this keyboard with a third-party charger and/or cable.
Thus, there are real safety issues that make it a prudent choice to shut down and not attempt anything when something, like voltage drop, appears out-of-spec.
