    The wife and getting ready to purchase iPP 12.9 units. I went ahead and got us each 29watt power supply and a USB-C to Lighting cable. Even our current iPad Air 2 units charge faster with that unit that the traditional 12watt units. So when we get our iPP units, likely we will leave the 12watt units in the box.

    12w ps is what Apple ships with all iPads. I recommend the 29w ps for anyone with any IOS devices. Charging will happen as fast as the device can handle the power.....not as slowly as a 5w or 12w ps can deliver it.

    Your assertion that "current iPad Air 2 units charge faster with that unit that the traditional 12watt units" is somewhat suspect - are you sure you were using a 12W charger? If you refer to Apple's own website, under the FAQ section:

    Typo on my part. Out iPad Air 2 units seem to charge faster via the 29watt ps compared to its 10watt indeginous ps.

    Because it then charges at 12W, most likely.

    Personally I would use the supplied charger for overnight charges and the 29w for day to day use.

    Is it safe for the battery to charge IPad Pro 12.9" with 29w USB-C charger?

    I ask an Apple Rep today and he was against me buying it. Said it will hurt the battery and to stick with 12W charger.

    When using the the 29W adapter the 12.9" iPad Pro charges using 14.8v @ 2A using USB Power Delivery protocol (normal usb is only 5V). This requires special hardware support to even make it work so no worries about damaging the battery, the iPad Pro is designed for it.

    Here is some more info: https://www.macstories.net/ios/testing-apples-29w-usb-c-power-adapter-and-ipad-pro-fast-charging/

    If I do go ahead and buy the USB-C charger, can I also use it to charge my other devices like iPad Pro 9.7", IPhone 7 Plus and IPhone 6s?

    Went ahead and bought the USB-C Charger.

    I did notice that the iPad gets charged quicker. Nice. Glad I got it. My other devices also get charged but more or less same as what the 10W charger could do.

    When the USB-C to Lightning cables (1m & 2m) were introduced, Apple specifically noted that combining them with the 29w USB-C charging brick would quick charge 12.9" iPP.

    Another consideration for the 29 wt charger is that the 12.9" pro will actually discharge faster than the supplied charger can charge it if streaming video. That was my primary reason for going the 29 watt route. The Pro uses quite a bit of power streaming video and I love to binge watch shows while on the road. As I am a truck driver, the pro is not only my workhorse for my business, but it takes the place of a DVD player and TV in the truck.

    I just picked up both the 29W Power Supply and a USB-C to Lightning cable for a steal.

    It's a must have for any Apple iOS user (let alone iPad Pro owners).

    Best price anyone has found on these 2? Price seems a bit steep...

    You don't need the apple usb c charger, anker has some multi-port chargers with USB c for a good price. Just to make sure it supports USB-c power delivery for fastest charging (i believe anker has one that support 40w output on USB-c port)

    Be well informed about what you're getting from Anker's USB-C offerings. I would be extremely cautious about it. I bought and reviewed one of Anker's USB-C chargers, and it doesn't charge at 29W.

    There is a very well informed discussion about 29W and the 12.9" iPad Pro at https://forums.macrumors.com/threads/87w-usb-c-charger-doesnt-charge-12-9-ipad-pro-29w.2015416/

    I'm sorry I don't have a USB-c PD power tester, so I can't say for sure for iPad. And you know those apps aren't usually accurate. *Some* of those app just calculate how fast the percentage of battery is charging, so it CANT take it into consideration that the iPad Pro itself is consuming ~12w power when using.


    However, the anker charger does charge my MacBook Pro at ~40-50w, so I say it's powerful enough to output 29w, unless there's something weird about USB-c that allows dynamic power adjusting on macbook, but can't charge iPad on 29w.

    The App was quite accurate, but was discontinued when apple shut down the APIs that allowed the app to read the actual current and voltage data.

    If you've read the second link I posted, you'll see that it's been established the iPad Pro requires a very specific combination of power characteristics to charge at 29W. Not even Apple's own 87W USB-C adapter charges the iPad Pro 12.9" at 29W.

    That would be interesting to learn about indeed. Let us know what you find... but so far the only other USB-C charger that does 29W on the iPad Pro seems to be the Ventev one - https://mobileaccessories.ventev.co...rgers/4468042__Ventev-wallport-pd1300-Charger

    Since the USB-C to Lightning cable appears to be capped at 2A, I would think the MacBook / MacBook Pros would be limited by how high of a voltage they can negotiate with the iPad Pro 12.9".

    Correct me if I'm wrong, but beyond 12W charging for an iPhone or iPad, there's no reason to use this 29W charger unless you have the 12.9" iPad Pro right?

    Or if you have the 12" MacBook.

    That's right, good call. The 12" MacBook includes the same 29W adapter right?

    The comment just threw me off, that for any iOS user the 29W charger is a must. Wanted to make sure I wasn't missing any opportunity to charge my 9.7" faster.
