iPad Pro 87W USB-C charger doesn't charge 12.9" iPad Pro @ 29W

Not sure if it's well known (or even that interesting) but kind of applicable to this thread. The 10.5 iPad Pro comes with a 12w charger now, last year 9.7" was 10w.

There's quite a few USB-C - Lightning copies on Amazon now I noticed. Think i'll pick up a genuine one to test the charging from 87w, 60w, 29w USB-C chargers, plus from the MacBook Pro itself. I can also test it from an iMac with a USB-C port too - I assume they are limited, but hopefully it can do more than the MacBook Pro's USB-C port which is limited to 15w.

Planning on getting the Anker USB-C charger which I think goes up to 45w so we'll see what speed that can charge at too.

I don't find charging the 10.5" with the supplied 12W charger a problem. It's pretty much what I'm use to from the Air 2. It would be great to know though if it properly supports the USB standard for faster charging negotiation rather than the mess on the first gen devices. I think the big issue was/is really with the 12.9" where you really need more power. I'm interested if that one has been updated in any way on it's support for USB compliant chargers.

I bought too Plugable USBC-VAMETER; I hope to post a report about it within a week.

I lied. Even if I would had claimed "next year", it would be a lie. I am not going to write a report nearly as long as that one about Satechi Type-C Power Meter. I do not "quit" due to lack of time; I "quit" because I am not motivated and I do not care. I dislike both Satechi Type-C Power Meter and Plugable USBC-VAMETER. They both flicker, neither seems durable.

Their circuit designs are similar. Between Type-C receptacle and microprocessor, their circuit boards are almost identical. See reference designators, clockwise from left: C9 C10 C15 R4 R5 R6 C16 C17 C6 U1 C3 C4 R1 C1 C2 U2 C7. Plugable USBC-VAMETER main controller (U3) is STMicroelectronics STM8S003F3 (package marked 8S003F3P6). Like Satechi, Plugable shunt resistance is nominal two milliohm (2 mΩ, mark code R002). Both units emit faint high-pitched noise. (It is very faint, not likely to be noticed in any but a silent room.)

If wanted to own one of them, then I would choose Plugable USBC-VAMETER. It is slightly more intelligent than Satechi's: Plugable's does not display an arrow when measured current is zero, and its measurements are rounded to three hundredths. (So Plugable might display 1.93A and 1.96A while Satechi display 1.92A 1.93A 1.94A 1.95A 1.96A 1.97A.) Plugable's receptacle is anchored to circuit board at its four corners, making it more durable than Satechi's; its C plug is not well braced, just like Satechi's. My specimen was assembled with cyanoacrylate (SUPER GLUE); its vapours coated the whole circuit assembly. After cleaning, its screen display is appreciably brighter.

I would much rather have a power breakout cable, something like: basically an extension cable with three banana jacks, or three test points in a lump. (Like those cables which have ferrite cores on them, imagine a cable with a test point chunk on it.)

Huh, really? Not saying I don’t believe you, just surprised. The iPad Air came with a 12w adapter, and the iPad 2 came with a 10w. I still have both and use my 10.5’s 12w as well. Interesting that they lowered it on that.
 
Slightly off topic but if anyone was thinking about needing the 29w USB-C charger to charge iPhone X or iPhone 8 at full speed, you don't. All Apple USB-C chargers will charge it at full speed as the "high speed" charging for the iPhone is actually only 18w.

There are no Apple USB-C chargers below the 29 W model.

I don't think so. He wrote about not needing the 29 W Adapter.

Also, as he said it's not a topic previously mentioned in this thread.

This whole thread has been talking about how the 29W charger can charge an iPad Pro faster than a 61W or 87W charger.

He was clarifying that for the iPhone 8 and iPhone X, the 29W will be no faster nor slower than any other USB-C charger because "fast charging" is actually 18W on iPhones compared with 29W on iPads.

Buuuuut he also wrote "if anyone was thinking about needing the 29w USB-C charger to charge iPhone X or iPhone 8 at full speed, you don't".

How could that be misunderstood? Or perhaps he meant something else, like the 10 or 12 W USB charger, which are not USB-C though.

Well, you have misunderstood! He is saying you don't need the 29W charger - you can use a 61W or 87W one instead.
