    I haven’t bought the new iPad Pro yet, because its sold out everywhere, but I’m planning to buy it eventually. My concern is that I purchased the iPad Pro fast charger last year which I use for both iPad and iPhone. I don’t wanna purchase a new fast charger, so can I use my mbp usb-c charger as a fast charger? And another question: How do I cope with charging the iPhone now? It’s such a hassle to to back and forth. I do have a Mophie wireless charger, but I barely use it because for the last 6 months its been inconsistent with charging my phone. It has to sit perfectly to detect it. I really hope the next iphone will have usb-c, so I don’t have all these different kind of chargers tangling up on the floor.

    If you mean the 29W charger, you can still use this with the new iPad Pro. Just use the lead that comes with the Pro with the 29W charger.
    Or...... yes, use your MacBook Pro’s USB-C charger. It won’t damage the iPad Pro as it will only take the power it needs.

    What do you mean by “the lead”? Sorry, English is not my first language so I’m not familiar with all the technological terms, lol.

    No problem at all..... My mistake.
    The ‘lead’ I mention is ‘the cable’ that comes with the iPad Pro.
    UK people sometimes use the word ‘lead’ for the word ‘cable’. Cable is more used for TV providers like Sky, Virgin etc.

    Got it! Yeah that’s a really good idea, then I can just plug the different cables into it when going back and forth between iPad and iphone.. but it’s still going to be annoying. Isn’t there a third option? Like a tiny adaptor I can attach on to my mbp charger that turn it into a lightning charger for my iphone when necessary?

    You could use this:- USB C to USB 3.1 Adapter[2 pack], USB C Male to USB Female, Converting USB-C (Thunderbolt 3 Compatible) to USB 3.1/3.0 Support OTG for MacBook Pro 2018/2017, Galaxy S9, Dell XPS & All Type C Devices https://www.amazon.co.uk/dp/B077FY7831/ref=cm_sw_r_cp_tai_XjS5Bb55F39MS

    Attach it to your mbp/charger then attach the usb to lightning cable that came with your iphone.

    Yes, you can use the MBP charger. If it’s the 61W or 85W charger, your iPad will charge at 18W (same power as the included charger, so the only advantage is convenience). 30W charger is faster.

    As for your second question, get a lightning to usb c cable.

    Yes, everything USB-C will work. That's the standard, and why they made it, and why it's a very good spec.

    Hi. Just to be clear what is the highest watts that the new iPads can charge. Will they charge faster if you use a charger that is higher then 18 watts?
    Thank you.

    ^This. The question has come up many many times. I feel like I've answered it myself a dozen times.

    You can charge at 30W with a 30W USB-C charger. I have read from people who have tested that the 2018 Pro reports the ability to charge at up to 45W, but in real world test it was pulling ~38W. I can't recall which PD profile was being used.

    There's some great discussion in some threads here about chargers.

    With USB-C, it's all based on Power Delivery profiles. Different combinations of voltages & amperages. I don't know the exact details for the 2018, but for the 2017 Pros they had to drop to the highest compatible PD profile that the 61W and 87W chargers provided, which I think was actually ~12W (5.2V @ 2.4A)?

    With the 29W adapter at the time, it was using a profile of 14.5V @ 2A.

    Here's one of the threads: https://forums.macrumors.com/threads/87w-usb-c-charger-doesnt-charge-12-9-ipad-pro-29w.2015416/

    Ahh, I see. Thanks for the explanation, I have no idea about any of that. I will do some testing as I have a 87W and a 29W charger I got for fast charging my iPhone earlier in the year.

    Yeah, you can really start going down a rabbit hole reading about all that stuff. The 29W definitely works nicely. Curious if the 2018's will draw more from the 61W or 87W.
