Weird, I see a lot of comparison of Anker Power IQ vs Quacomm QC… and also USB Power Delivery vs Qualcomm QC… but have not been able to find any real world comparison of Anker PowerIQ vs USB Power Delivery on iPhone.
On Android phones there seems to be very little to no difference between Anker PowerIQ vs USB Power Delivery since most phones are limited to 18W (Anker Power IQ max)… but have not found any real world testing. From Anker’s literature it would seem, like on Android there would be little difference, but no one seems to test this… not sure why.
Thanks for all the replies guys… PowerIQ 1.0 maxes out at 12W… PowerIQ 2.0 maxes out at 18W
Did a little experiment… really wanted to see if I really needed to by a USB-C to lighting to get fast charging and it seems like you don’t… it kinda seems like it’s more about what the phone can do + max wattage of charger and if it has a mode (Volts and Amp) that matches up to phone…
I tested a RavPower with 18W 5V/3A “QC” USB Type A Port (don’t think this is Qualcomm QC) Beats USB-A to lightning cable… and performed pretty much like description of USB-C PD charge speeds… haven’t actually tried… could be marginally faster with USB-C PD, but really seems like there is nothing particularly magical about USB-C and/or PD… no need necessarily to buy a USB-C to lighting cable like everyone says… ymmv…

There are a lot of fast charging standards out there, as you’re seeing. Most phones only support one officially, but by its nature could work with others. How much your charger’s output is doesn’t matter so much as it supporting a compatible fast charging standard.
Anker PowerIQ (aka PowerIQ 1.0) has a max output of 12W. It was made with the old Apple 2.4A standard in mind. It’ll fast charge iPhone 4 through today’s models. But newer iPhones can charge a bit faster using USB Power Delivery.
Anker PowerIQ 2.0 mimics Quick Charge 3.0, supporting the same power profiles. As such it fast charges Samsung phones. As well as Android phones that support Quick Charge. It also tends to support the old Apple 2.4A, so it can fast charge iPhones with their older standard.
Qualcomm Quick Charge 3.0 is connected to Qualcomm’s mobile processor chips. As such only Android phones will support the standard. Samsung and Motorola use their own standard which mimics QC, so they tend to be compatible. iPhone will never use QC, as Apple won’t give up making their own processor.
USB Power Delivery is an open standard that works through USB-C connections. It ranges from 15-100W. Though most phones hang out around 18W. iPhone 8 and newer models support PD. As do Google Pixels. It is uncommon on Android phones in general, due to Qualcomm’s grip on the device makers. PowerIQ 2.0 is completely incompatible with PD.
Fast charging in general works from 0-50%, then drops off. By 70% it stops altogether, with normal charge rates taking over. The point is to get your phone some power (~50%) in as short an amount of time as possible (under an hour). Doing so produces heat, which over long term can impact battery life. So fast charging cuts off between 50-70% (depending on phone model) to save the battery’s lifespan.
So just to be clear… you are saying that PowerIQ 2.0 will not support 5V/3A necessary to fast charge, fast charge compatible iPhone?
have a bit of a mystery with that “QC” labelled, USB-A, port the RAVPOWER… does appear to fast charge my iPhone 8 Plus with a 0-50% in 29mins… other of their charges do have Qualcomm logo… this one doesn’t… I’ve posted a question to them what protocol this port supports… waiting on baited breath for their response
If the USB-A port that supports Quick Charge 3.0 also supports Apple 2.4A, then it can fast charge an iPhone. That is likely what is going on with the product you’re using. It isn’t the Quick Charge tech that is doing the fast charging. It is the Apple 2.4A tech. They just both use the same port.
From a marketing stand point it is common to advertise QC but not Apple 2.4A. I have to test for Apple 2.4A when doing my product reviews, because it is rarely mentioned in the user manual or marketing materials. When I post reviews I make a point to list all fast charging standards my tester detects.
So another update… got an Apple USB-C to Lightning cable and tested…
Bottom line… no difference in charge time between the 18W USB-C PD vs 18W USB-A QC - 5V/2.4A. Time for each incremental 10% charge was within 1min except last 90-100% where the PD port took 14mins more than 5V/2.4A port.
Anecdotally the phone seemed warmer during 5V/2.4A charge so PD might be doing something fancy under the covers to persevere battery better…?
