    Has anyone seen confirmation the 10.5 supports fast charging via USB-C? I know the 12.9 Pro has since initial launch. 9.7 Pro didn't. Thinking about picking up a 29W charger if it does.

    From what I’ve read it does but I don’t have a link to confirm it, someone will soon enough.

    I have a MacBook so I’ve bought a USB-C lightning cable on the basis that it does support fast charging.

    This. It was mentioned during the unveil on stage that both models will charge faster with the USB-C chargers.

    What is a USB C charger?

    Is it safe, charging too fast can be damaging

    I think they were talking about both in the presentation but i would wait and see after people get their hands on it and try it out

    It’s safe. If you use it with an iPhone they phone will not take more voltage than it can handle.

    Yes. It's fully supported ^_^. I bought one for my 12.9" and it's fantastic. You will absolutely notice a difference. Before buying one I couldn't run intensive apps when plugged in and have the battery percentage increase. With the 29w charger it's a breeze.

    Just actually got that today for my 12.9 pro. Can’t wait to see how fast it’ll charge now. Also got it for my 10.5” coming Tuesday.

    This is from a MacStories article about the original 12.9" iPad Pro and fast charging:

    What's better for the battery?

    To charge the iPad slow or fast? 12W or 29W?

    Generally slow charging is said to improve battery cell longevity

    12W is slow charging it. 29W is normal charging it, there should be no harm to the battery.

    It fast charges to 80%, then it goes back to trickle charging. I don't think the battery will be affected too much by this. If you decide to charge it while letting it sit in the sunlight it might be affected though :D

    The fast charge to 80% is the the standard charging profile for lithium batteries - applies whether 12W or 29W is used I would say?

    Don't know if you can say 12W is 'slow' and 29W is 'normal', as the 12W is what ships with the device.

    Well if the device is discharging faster than the 12W charger can charge while in use, I would say it is slow. Apple seems to be milking the $75-$85 accessory right now though for anyone who wants to charge in a reasonable time. That's fine I guess, but I would expect that charger to be included sometime in the future.

    I would. It has been found that the iPad Pro is designed to be charged at 29W, Apple just wants an extra $50 plus $25 out of us.

    The same question has been asked well over a year ago, and I am many others have been using the 29 W charger for both iPad and iPhones without any issues whatsoever. Also on the sales site for the 29 W they show a compatibility list and the iPad and iPhone are included.

    So, could I assume any device would be safe with the MBP 15's 85W charger? Is there a limit to iOS devices' ability to handle high power chargers?

    I believe the way it works is the phone will not accept more than it can handle. So going by that, yes you can use the 87W MBP charger and it should be fine but it will not charge the phone faster.

    I agree they're milking us now for the 29W + usb-c cable.

    I love the idea of fast charging, but what's best for the 10.5" batteries health and longevity?

    Short of convinving evidence, it's hard to argue that what comes boxed with it, a 12W adapter, will not be it.

    penajmz: When you mentioned 'it has been found that the iPad Pro is designed to be charged at 29W.' doesn't the same point apply? That is, it comes boxed with a 12W adapter?.. Just because a 29W *can* charge the device faster, does it mean it's better for the batteries life?

    Post #11's sceenshot above mentioned the 1st gen 12.9" (more demanding than the 10.5), while playing Oceanhorn (a graphically intensive game) at full brightness, charged the device by 1.2%, so.. that's not discharging faster than the 12W can charge while in use, which I'd assume would be a higher percentage rate with the 10.5". I agree it's slow, but the great majority of user's do not use their device's consistently like this.

    ABC5S: Cool, but would you agree that just because there's been no apparent issues from using the 29W, it may not be what's best still for the life of the battry?

    Apparently the 29W charger outputs either 5.2V at 2.4A, or 14.5V at 2.0A. The 1st Gen 12.9, and both 2nd Gen Pro's, must be set to accept the 14.5V as their first choice, that's compelling, however.. What's best for our new 10.5" batteries still? :)

    I guess just use the 12W... I mean it comes in the box and all... Knock yourself out.

    What I plan on doing is to see how my usage compares to the battery life. If I find my usage demanding that I need to frequently charge, it's a worthy investment. Otherwise, overnight snail charging is fine for me.

    I wonder how smart chargers like Anker would fare? They have up to 12w per USB jack, but are supposed to maximize in a "smart-charging" way, so if the iPad Pro signals it can accept ≥24w and especially if only 1 USB in a 24w 2-port charger is used, can it deliver 24w charging speed?

    And actually this one seems pretty affordable:
