Clarification from Apple, you can use an third-party USB-C power adapter that supports USB Power Delivery (USB-PD) (plus the official USB-C to lightning Cable of course)
https://support.apple.com/en-us/HT208137


Not from Apple you don’t, any third party will work..

What Apple fails to mention, is that (for fastest) charging you'd need a USB-C charger that supports 2 amps @ 14.5 watts, which is very rare, outside of Apple's own 29w MacBook charger.
 
Well...
Not sure what kind of “fast charhing” is this but my iPhone 7 Plus which does not support fast charge just charged up from 0-100 in exactly 100 minutes using Apple 29w/USB-C/Lightning cable.

0-50% in 35 minutes. That’s something close to the promissed 50% in 30 minutes.

The phone was connected to the Wi-Fi, LTE, and I was using notes time to time. iOS11.

P.S. That’s 20 minutes faster than it took for somebody to charge the 8 Plus using the same method:

What do you mean "fastest". Like the fastest that will be supported with the phone? So we wont see the speeds as if it was lower than 2amps @14.5 W?

If a 3rd party charger really supports USB-C with Power Delivery of 2A + 14.5w, then you'll get the fastest charging.

BUT... you can't confirm this via "timing" the charge, you need a Kill-A-Watt, to verifying the draw of ~30w to the device.

So the one i just showed you that i ordered is good right? And my CAR CHARGER HAS 20v-2a but that will dim down to 14.5 right?

Anyone recommend a good third-party usb-c power adapter with UK plug?

search, does anker make them. i am not to famliar with UK ones.

My 8+ took 3h15min from 0 to 100% with the standard Apple charger.
Got the Apple USB-C 29W charger + lightning cable today and will let you know how long fast charging takes.

But u said it has to have an output 14.5-2a and that’s what it has.

Third party chargers “say” lots of things. This is one case where someone will need to measure/test before I feel confident about buying one. 2A/14.5W is technically out of compliance with USB-C Power Delivery specs, although Apple’s 29W charger might be grandfathered.


Right, but it doesn’t go into the level of detail I provided.
 
Seems very detailed to me. If you're going to buy a 3rd party charger, it has to support USB Power Delivery
  • A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)

Your details are uncorrect, Its not matter of amps and Watts but Power Delivery Profiles. The Macbook Pro retina 86W adapter for example has 3 power delivery profiles (5.2V @ Max 2.4A, 9V @ Max 3A and 20V @ Max 4.3A), the iPhone 8 will certainly use the second profil (9V at max 18W) https://en.wikipedia.org/wiki/USB#PD
 
The famous software update is required to use fast charging as we all know yet.
Am just "fast"-charging with Apples 29W USB-C + USB-C lightning cable and those are the figures starting at 85% (I know I should have started at 0% but will do that at a later point in time).

Right now fast charging is not working with this setup on the iPhone 8+: 85%-97% in 30minutes

Yes, but there's many different flavors of USB PD. Which Apple does not go into, via that support article, i.e. no mention of the different Power Delivery from the 61/87W (18W delivered) vis 29W delivered from their 29W MacBook charger.

^^^ These are nuances that we've already measured/tested, with the newest iPad Pros.

As I've stated, you can't use "time to charge" as an accurate indicator of power delivery. Apple's hardware slows down charging as the battery nears full capacity.

Full wattage is delivered when the battery is <50%, then things start to slow and taper off. So, try it again with your battery drained, and I'm confident it will meet Apple's guidance on time.

But time to charge is all us “users” care about. When it comes down to it, that’s all that matters in the end, You know. I think fast charging is only a term for the first 50% if the battery. After that not sure what we call it, not-fast-charge. Lol

Yeah, users care about "fast charging" when their phone is near-dead. That's when you need the fastest top-off, not when it's already at 88%.

Notice Apple explicitly states Fast charge "recharge(s) iPhone up to 50 percent battery", not "Fast charge works from 88% to 100%". https://support.apple.com/en-us/HT208137

I think a lot of people think “fast charge” means how long it takes to get to 100% creating all this confusion. But the same cords and chargers for fast charging should charge the same speed for ip7+ and 8+. They just didn’t advertise it. I mean we are talking 50% in 30 min with ip8+ compared to 50% in 34 min with ip7+. Regardless the Oneplus 5 can go from 0-100% in 83 min while being 38% more efficient with INOV and still be blazing fast! So just makes IP look pathetic...

Incorrect. Only the 8/8Plus/X/10.5 and 12.9 iPads have the internal USB-C chip that support the 18w/29w delivery.
 
That’s not what I am saying. Regardless of what it says it supports, the 7+ still charges at a faster rate with the usb c cords. Correct it’s not suppose to but it does...

The max a 7 Plus will support is 2A @ 5V (i.e. 10W), regardless if you're using the USB-C charger + Lightning to USB-C cable, or the old 10w/12w "iPad" brick plus standard Lightning to USB-A cable.

If you can show a pic of a 7 Plus pulling more than ~10w (e.g. 18w or 29w a la 8/8Plus), please share!

I have personally tested this (and other scenarios) myself with an actual meter and applicable cables/bricks. And posted results to this forum. 7/7 Plus don't support any "fast charging" beyond 10watts, just like all other previous iPhones, going back to the 5.

We have done more testing in this thread, and here is an informative video in this post: https://forums.macrumors.com/thread...-party-adapters.2052414/page-10#post-24820433

 
As I told previously in this thread: My 7 Plus charged from 0-100% in 100min (0-50% in 35min) using Apple 29w/USB-C. I don’t care whether you call it fast charging or something else, but it seems to charge faster than some iPhones 8 here so far... ;)
