Wait for Anker charger with Power IQ2?

I've recently got a new iPhone 7 and am now looking for another charger. At my parents I have an Anker PowerPort+ 5 USB-C with Power IQ. According to the technical data, it delivers per USB 2.4A at 5V. I have now charged the iPhone for the first time and am pleasantly surprised.
Anker has now introduced the PowerPort II, a first power supply with Power IQ2 and these specifications: 5V 3A, 9V 2A and 12V 1.5 A - Link
But I'm more interested in the PowerPort+ 1 with Power IQ (charging similar to the PowerPort+ 5).

Does it make sense now to wait for a single charger with Power IQ2 (successor for the PowerPort+ 1)?
Can the iPhone 7 use these other charging parameters with voltages above 5V at all?

iPhone 7 can't charge at anything other than 5V, and does not support PD or anything like that. 12W (which is 2.4A at 5V) is about the fastest it can charge. So the PowerPort+ you have is already the most it will take.

Right, only iPhone 8 and up charges faster with Apple's 30W USB-C charger.

Probably not. According to Apple's support page, USB Power Delivery was added on iPhone X and 8 series and it requires USB-C connection and USB-C charger. If you want your purchase to be future proof, by all means wait.

If you are in the waiting mode, there's also a rumor that Apple will be introducing a smaller 18W USB-C adapter with upcoming iPad Pro, which will support 9V 2A (9V x 2A = 18W) for faster charging.

I would also encourage caution here. In general, fast charging is generally bad for lithium batteries. Sure the iPhone 8, X, Xs batteries were designed to charge that fast, and they can be charged that fast if needed, but generally slower charging is better for battery longevity.

A regular 1A/5W charger will easily charge any iPhone to full overnight. For daily charging, that kind of slower charging is probably better.

Save the rapid charging for the situations where you actually need it.

I normally charge XS with a wireless charger, but switch to USB-C charger when I am in a hurry. Apple's fast charging curve tends to be far more conservative than Android phones, so I suspect using fast charging regularly would be fine for iPhone. But if you are charging overnight, it certainly wouldn't hurt to use slower chargers.

I second that. Just handed over an iPhone 7 always charged over night with the included 1A/5W and the battery capacity after more than 500 charging cycles was still in the 90s.
