The QC 3.0 18W power adapter itself is worth nearly 1/2 the cost.
Hard to find detailed info on this thing but it seems that it does support 7.5W with iPhones on the latest iOS 11.2/12.x
More info I found but this may be dated:
"7.5W wireless charging for newest iPhone X / 8 Plus / 8 is enabled in the latest iOS 11.2 update faster than traditional 3.5W-5W slower wireless chargers. Compatible with All Qi-Enabled Phones: Includes iPhone X, iPhone 8, 8 Plus, Samsung Galaxy S8, S8 Plus; non-Qi enabled phones are still compatible but will require a Qi wireless charging cover to power up. Fast & Free 24W QC 3.0 Adapter: Includes a powerful Quick Charge 3. 0 adapter that boosts the max output to 10W so selected Samsung Galaxy, Google Nexus, or Microsoft Lumia phones can charge even faster.
