Hi,
I was going to buy an Anker quick charge plug (it has Qualcomm quick charge 3.0 and Power IQ) but on the plug I’ve noticed it’s a USB connection so I’ll need a usb to lightning lead, but I’ve seen other plugs where it’s USB C so I’ll need USB C to lightning instead, is there any difference between the two plugs and also the two leads?

Many thanks

The absolute fastest way to charge it would be any USB-PD capable charger (Hint: it'll have a Type-C connection) with Apple's or any MFI certified USB-C to Lightning cable. The company Choetech sent me both an 18W charger and their own 6ft USB-C to Lightning cable that's MFI certified and it charges my iPhone Xs really fast. It can keep both the phone and smart battery case climbing really fast.

The Apple 12 watt iPad charger will charge it just as fast as any other super fast charger. The charging circuit is built into the iPhone and it can only accept a certain amount of current. A 65 watt charger (for example) won't charge an iPhone 8 any faster than the 12 watt iPad charger. And if it did, the difference in time would be unnoticeable.

I use both the tiny 5 watt cube that comes with the phone or the 12 watt iPad charger on my iPhone. Something to keep in mind is that a 12 watt charger or bigger will significantly heat up the battery during charging. It will get much hotter- which isn't good.
During the summer on hot days using a fast charger when the phone is already hot is a bad idea. Once the battery gets too hot, the charging circuit inside the phone starts cutting back the current going into the battery- so your fast charger isn't fast charging at all - just trickle charging

That's incorrect and there are plenty of tests online that show otherwise. The Apple 29W or 30W adapter will significantly speed up charging.

First of all, iPhone 8 charging peaks at 19.5W. It's not just about wattage either, it's about voltage too. The iPhone 8 adopts USB-PD which means the voltage goes up to 14.5V. The standard 12W iPad charging offers neither of these characteristics.

I use the 29w USB C Apple charger and a Apple USB C to Lightening cable for the fastest recharging experience. Both items are required (assuming you wish to use first party products).

Follow these links to the empirical tests that have been performed.

Cliffs Notes version -- a 12W iPad charger is fast, cheap, and doesn't require special cabling.

An 18W USB PD adapter, plus the required cable, will be slightly faster, but not by a large margin. Going above that would be a waste for an iPhone, which has a small battery and won't draw more than 18W. An iPhone with the battery case, or an iPad with its larger battery can take advantage of a higher wattage adapter.

Apple devices don't use or understand the QC protocol, so a QC adapter, or port, makes no difference.

QC4 will bring some cross-compatibility with USB PD, so things will get simpler then.
