However, as it stands the Ineteck 60W is cheaper to purchase than both the old 29W and newer 30W charger AND the Ineteck comes with a free 6ft USB-C cable which you would have to purchase as an additional extra from Apple.

Link Me Up Scotty, LOL!...Please!

Continues to amaze me that people will spend loads of money for Apple devices and then try to save a small percentage on after market power adapters and cables.

Tear downs of power adapters have shown inferior components, skimpier circuit boards, and most alarming the air gap and insulation between the 110/220V circuits and the DC output circuits to be criminally inadequate in a number of after market power adapters.

There have been some excellent tear down studies published. Look them up and then decide if saving a few dollars is worth the risk of getting high voltage transmitted to your device and you.

Labels and output tests don’t mean much if the inside is junk.

(10/8/2017) tldr; Chart of % gain over minutes for the Anker 30W charger described below, in case you just want to verify that your charger is charging at full speed.

Original post follows:

I finally managed to get my hands on both the 2nd gen iPad Pro 12.9" and the new iPad Pro 10.5", and I figured I'd run some tests on how they perform, both on the original Apple 29W USB-C to Lightning adapter, as well as some third party adapters.

I originally reviewed Anker's original 60W USB-C adapter, which reportedly supplies 29W of power to the 12" MacBook. Unfortunately it wasn't able to fast charge the iPad Pro.

With the new iPad Pros and the passage of time, I hoped that the situation would improve on both sides - Apple and 3rd Party adapters - so that 29W charging would be feasible without having to spend so much on Apple's 29W adapter. I did a quick search on Amazon, and I found 2 that looked promising:
The Aukey is cheaper and comes with an odd USB-C to 2 USB-A adapter, whereas the Anker has a more straightforward design.

Here are the electrical specifications:

Aukey

View attachment 704986

5V x 3A, 9V x 3A, 14.5V x 2A

Anker

View attachment 704987

5V x 3A, 9V x 3A, 15V x 2A, 20V x 1.5A

Apple (reference)

View attachment 704988


5.2V x 2.4A, 14.5V x 2A

The Anker is a little heavier, but seems better built, and also has the additional 20V output which would be suitable for MacBook Pros.
  • Battery Drain Methodology: I downloaded GFX Metal Bench and used the Battery loop test. I'm not sure if there's another tool that has a better way of draining the battery.
  • Power Drain Meter: I used the Zhurui PR10-E US15A. It seems to have a good review.
  • Cable used: Apple's official USB-C to Lightning cable, 1m
Here are the results of the testing:

iPad Pro 12.9" Gen 2

Battery Level: ~33%

View attachment 704991

All 3 seem to charge at 29W!

iPad Pro 10.5"

Battery Level: ~34%

View attachment 704992

Again, all 3 seem to charge at 29W, although it seems to be slightly lesser for the 10.5" iPad Pro.

Overall, I think this is good news! It looks like either the USB PD circuitry in the new iPad Pros or the 3rd party adapters are now in sync.

If you're deciding on which one to buy, the Aukey seems like a good option if you're on a budget. It's also lighter and has the option to convert to 2 USB-A ports, although that seems like a gimmick.

The Anker seems better built, and I suspect that the 20V output can be useful if you want to use it to charge the latest USB-C MacBook Pros.

Either way, I think it can be safely said that we no longer have to rely on the Apple 29W USB-C adapter to charge at full speed.

Data points / Special Note regarding 10.5"

@BeatCrazy has actually already tested the 10.5", but his results were different in that he got a reading of only 18W - ref https://forums.macrumors.com/threads/10-5-ipad-pro-fast-charging.2050391/page-3#post-24713109

I have done some quick tracking of the charging progression and here are some data points:
  • 0 mins - 35%, draw 30W
  • 10 mins - 46%, draw 30W, gain/min = 1.1% / min
  • 21 mins - 57%, draw 22W
  • 33 mins - 67%, draw 22W, gain/min = 0.83% / min
  • 40 mins - 72%, draw 18W
  • 48 mins - 77% draw 18W
It looks like the 10.5" iPad Pro switches to a lower charging rate (probably 9V/2A or 18W) once it goes past 50%. It seems to drop again after 70% to maybe 15W.

Follow up data points:
  • 0 mins - 78%, draw 18W
  • 6 mins - 82%, draw 22W (outlier?)
  • 31 mins - 93%, draw 7W
  • 47 mins - 96%, draw 3.8W
Once the iPad charge goes beyond 90%, the charging speed drops drastically.
Nice results!

Why not saving money? There are also good third party adapters. Even Apple failed with some adapters:
https://www.apple.com/au/support/ac-wallplug-adapter/
https://www.apple.com/support/usbadapter-european/
Right, so show me where third party cheaper adapters provided upgraded replacement units for possibly bad units. Pretty sure AppleCare+ won’t cover damage from using knockoff money saving adapter.

I love saving money myself, but have learned you also get what you pay for. When buying a $1500 iPhone and a $2000 iPad makes no sense to me saving $30 on aftermarket adapter. I just don’t visit Starbucks for a week and money magically appears.

All i’m saying is buyer beware. Everyone has option to save on whatever they want.

We are drifting off topic but I am going to risk a moderators intervention:-
You say that only Apple offer replacement for faulty units.
Well, not exactly true.... Anker offer a full replacement on items purchased if found to be a manufacturing defect at any stage, on top of Ankers additional extra 12 month warranty.
Staying with Anker, they are as you know big in the US and they’re also the same in the UK. I doubt Anker would quibble in helping a customer if one of their items damaged an Apple product.

Personally, I have used Anker for years. I have never ever found any of their products to be nothing but perfection. They are tested thoroughly and have to pass a very rigorous EU test just to allow the products to be sold within the EU.
Apple are greedy enough as it is. If I can find a way to benefit my wallet then I will do it.

Well, not exactly true....

Please show me where I wrote only Apple offers replacements for faulty units. I asked an open question for anyone to show me where third party products have done something quite specific. The two sighted posts showed where Apple not only replaced faulty products, but actually replaced potentially faulty products across the board, even if the individual product had not failed.

You have stated your belief that Anker would replace manufacture’s faulty product. Which sorta kinda gets to what I had requested. It’s always great when manufacturers stand behind their products. I’m happy you are pleased with Anker adapters. What you buy or don’t buy gives me no glee or remorse either way. Apple and Anker are but two of many manufacturers out there. Many of which have been shown upon disassembly and examination to provide inferior and even dangerous products.

Just to be clear I will quote what I actually did write.
Right, so show me where third party cheaper adapters provided upgraded replacement units for possibly bad units.”
I for one applaud any company that replaces product that may fail.

Personally, I've also had bad experiences with some Anker products. But they have great support and mostly well rated products. At the end you have to check the product reviews and/or tests.

I feel this is a terribly misguided view on the situation, and tries to equate "third party" with "low quality junk". Third party does not necessarily mean low quality. Branded power accessories from Belkin, Moshi and Mophie are available if you want to feel safer - these are high quality "after market brands".

The point of the discussion was not to promote "saving on after market power adapters" but to test the viability of Apple products adhering to the new USB-C Power Delivery standard, and it did. This means a lot - not simply just the availability of cheap and low quality power accessories. You can:
  • use USB-C laptop adapters for various brands e.g. this Wacom 100W adapter - which is most certainly not a "criminally inadequate after market power adapter"
  • use USB-C PD Power banks for even more portability and power on the go - a great option when you're doing long haul flights or just want to charge both your phone and your USB-C PD laptop at the same time.
  • have more options regarding PD adapters - e.g. a PD adapter with 2 USB-C powers, such as this one from Hyperjuice.
As far as possible, I have chosen to present brands like Anker, Aukey and RAVPower - all brands that should not be considered "criminally inadequate".

Ultimately USB-C PD is a standard that is meant to empower more choice for the consumer, not encourage dangerous and cheap power accessories. That is ultimately something that the consumer must exercise discretion when purchasing, but I'd prefer if people take away the increased versatility that is now available for consumers now that Apple has gone all-in with implementing a universal standard for power, instead of sticking with the proprietary Lightning and Magsafe connectors.

Interesting your stated concern was only Apple adhering to USB-C PD standards. Would have hoped equal concern of third party adherence as well.

The handful of brands stated is but a small percentage of aftermarket products being sold. In fact, Apple as well as the other as reputable brands you mentioned continue to be plagued with knockoffs labeled as name brands but incorporating inferior components, design, and manufacturing.

It remains, buyer beware when purchasing any power adapter especially from online mass marketing firms such as Amazon.

These fly by night Chinese companies could care less about adhering to standards or even safe products.

As far as being misguided, I could well say the same about your reply. It’s seems to my reading you are more interested in sticking it to Apple. I don’t own Apple stock, and purchase what works for me regardless of name.

I for one tend to believe that going to my Chevy dealer for parts and accessories helps to adhere to design and functionality for my Chevy. For sure there are aftermarket third party parts for my Chevy, but how do I vet them?

As I have stated previously, choices are good, saving money is good, but of equal worth, in my opinion, is the value of using what I am sure is at least as high value a product, as what I am plugging it into.

Perhaps a knockoff iPhone would be perfectly matched with a knockoff power adapter. As long as the external silk screening of Apple logo is accurate.

As far as standards are concerned it dismays me no end that now beyond the rated capacity of the power adapter, combined mix of voltage and amperage possibilities further complicates the evaluation process. 9v/2A circuit provides 18 Watts from 61 watt adapter. Newer version has but older version doesn’t have 9v/3A for 27 watts. So know version number of same advertised wattage adapter becomes important for max speed charging. This nonsense goes for Anker as well as Apple adapters. Order from Amazon and who knows what you get shipped.

Freaking Wild West!

Wow the cable issue and switching between various voltage/amperage combinations is another whole ball of wax rolling down hill.
[doublepost=1543963124][/doublepost]
61w Macbook provide fast charge for IPad Pro 3rd gen?

Fast charging is too vague. We need to start talking about specific volt/amp combinations for specific watts.

What can device take as combination. What will adapter put out combination wise. And also what will any give cable and imbedded chip transmit.

My life experience shows you throw one engineer at a standard and you get a complicated result. Throw multiple engineers from various companies and you get a standard that looks like a tangled mess of spaghetti.

I don't disagree with your concern regarding caution with third party accessories, but again you are missing the point regarding compatibility with USB-C PD. The consumer is free to buy whatever they want - the freedom is the point.

These fly by night Chinese companies could care less about adhering to standards or even safe products.

How in the world am I "sticking it to Apple" when I am applauding their conformance to USB-C PD? I'm not saying you should replace the internal battery or display with an aftermarket battery or LCD - your comparison with the Chevy dealer is bizarre.

The closest I can think of is going only to "Chevy branded" or "Chevy approved" gas stations. Is that what you do? That's fine, but the point is that there's a gasoline standard that gas stations have to adhere to, and drivers have the freedom to choose whatever grade or brand of gasoline they wish.

So suddenly your argument isn't about only buying Apple branded accessories, but how complicated the USB-C PD standard adherence is? I don't disagree... but you're really losing coherence in your posts.

I’m commenting on various posts, not loosing any coherence.

Gasoline is monitored and checked by state agency for meeting standards. Would love to see that for power adapters.

You totally forgot to comment on my mention that Anker has same issue regarding spec changes for supposedly same adapter.

I think my Chevy accessory parts statement makes perfect sense. I much sooner trust Apple to provide adapters (accessories) to their major product offerings that completely safely match.

The problem isn’t with Apple and 61 watt adapter adding output variations. Rather with an ever more confusing standard having to accommodate ever increasing variations of voltage/amperage.

Yes I can agree with this. Something similar to Apple’s MFi program would be welcome for USB-C PD adapters

You totally forgot to comment on my mention that Anker has same issue regarding spec changes for supposedly same adapter.

Essentially I don’t get how my comments could be interpreted as “sticking it to Apple” any more than your comments could be viewed the same way.

Apple is not infallible - a prime example of this is USB-C cable charging flaw. I would actually trust a true-to-spec USB-C PD implemented charger over an Apple accessory as a result, given the anecdotal evidence above.

The problem isn’t with Apple and 61 watt adapter adding output variations. Rather with an ever more confusing standard having to saccomodate ever increasing variations of voltage/amperage.

This is true. The USB-C PD specification has been quite a bit of a mess, but I see that it’s gradually leading to consolidation. I think this is something to be celebrated - eventually most third-party power accessories (excepting, I concede, the cheaper generic Chinese power accessories) will be compliant and reliable.

While it has been a mixed bag overall, I still firmly believe the USB-C PD standard is the way forward - hiccups in the standardization process have always been and always will be an issue, as is the case involving anything to do with getting people in different organizations (engineering, political or what have you) to negotiate - but that is not a good reason to dismiss standardization altogether.
 
Yes, I thought of doing the tests at differing starting percentages but instead opted for a balanced mid-range test ~ hence 60 to 70%.

I have though used both chargers (29W & 60W) from low to high charge and found it difficult to set them apart. I don't think the iPad Pro draws much more than the 29W charger.
However, as it stands the Ineteck 60W is cheaper to purchase than both the old 29W and newer 30W charger AND the Ineteck comes with a free 6ft USB-C cable which you would have to purchase as an additional extra from Apple.

It does draw more than 29W but not at all time.
>30W mainly when you are fast charging it and using it at the same time.

Just tested with the new iPad Pro from no battery (off) and charging it:

no battery (I can't say it's 0%) to 60% = 50 minutes
to 75% = 70 minutes
to 80% = 76 minutes
98% to 100% took a long long time...
to 100% = 140 minutes...
