[Zune55]

How do i know if the charger is pushing the full power to iPhone 8? Because there are 2 options on the output on the charger as you can see from my description & the box picture.

Don’t feel like spending $80 for officials fast charging apple accessories.

EDIT: Or do i need to i buy different cheap adapter with USB ports and use apple’s usb-c to lightning cable?

You keep on using the word "cheap." I'd stop spending money on cheap stuff that may or may not work.

Personally I'd just get a $19 12W iPad power adapter and use the cord the came with the phone. Been doing it for years ever since I noticed how much faster it charged versus the included 5W adapter.

It's almost as fast as Fast Charging and less headache.

44$ more and you could be headache free as well

You need to use Apple’s USB C to Lightning cable. It’s the only one certified and thus won’t be rejected. So that means you need a different adapter that Apple’s USB C to Lightning cable plugs directly into. (You we’re right to grab one that works for Nintendo Switch in a way though, as both iPhone and Switch require the adapter to be USB C Power Delivery 3.0 capable).

That’s true but when i see $49 price tag on the 29W wall charger my heart says no.

12W iPad charger for $19. 90% of the performance for 38% of the cost.

Wow that’s really good to know that its only the apple branded cable so far which can be used as fast charging i have another wall charger which has 2.1A output and has a USB port. Do you think this will charge fast if i use Apple’s USB-C to Lightning cable?

I have the 12W one but really like to see how fast iphone 8 will charge. I am also using 12W for almost most of my devices but that itch in me.

Or an Anker ($11 currently on Amazon) or similar 2-port 24W charger (12W @ 2.4A each port). You get the performance, two ports, and can charge just about anything without special cables. I have one in my travel kit and has worked like a champ with my iPhones and iPad.
