Want to fast-charge your iPhone 8 on the cheap? Here are 5 compatible USB-PD adapters

Not really. Most of tgose fast chargers are less than 30W/3-5A and in many cases are 15W/2.1-3A. The bricks that ship with Motorola Z Force phones are 30W @ 5.7A and cost $30-40usd if purchased separately. The regular Moto Z ships with a 15W charger and costs less if purchased separately. So USB-PD chargers aren't that expensive.

15watt charger should already charge the phone about 3 times as fast the puny 5watt charger iPhones ship with..... Apple could have at least redesign the charger they have been selling for like what, 6 years now?

The point is that the Apple fast charger is 29W which means the price isn't all that bad considering and those chargers that cost less than $20 are 10-15W @ 2.4-3A charging. Yeah the 15W/ 3A charger would charge the iPhone very quickly especially since the capacity of the battery is less than 2800mAH. A 29W should charge the new iPhones quicker than the quick charge on my Moto Z Force... or at least it should.

Only in theory. The software and the hardware controls how fast it would actually charge. Samsung chargers aren't even 15W and yet charge a 3300 battery in 1:40 mins. The S7 edge in 88 mins and the Note 7 on 108 mins.

I doubt the phone uses the full 29W think sheep. Apple already had those for the 12" macbook. They were too lazy to introduce a lower wattage brick or maybe for consistency and the higher margins. Most phones use like 15-20W so an iPhone with tiny battery and 29w should charge instantly.

Because they are standard and don't need Apple proprietary lightning connector on the end; which raises the cost of an Apple charger.

How does this compare to Samsung's inbox fast chargers?

Android smartphones aren't regular phones... If that's what you're implying here.

Nobody cares because of Android phone are reliable and do have affordable choices to mobile computing. While everyone is on to Apple because it's such an outrageously expensive and poorly made product that makes it a ultimate whipping boy, their fans the fool.

And how fast those things get to 90 % ? That is like 40 minutes less than 100 on the iPhone. And how fast those charge with the screen on ?

It is claimed the Galaxy doesn't fast charge when the screen is on, but simply says it does. It is a lie. Yes it takes longer to charge while the screen is on, because the screen is draining power as the phone is charging, as does any product. But it still charges faster than it would vs using a standard charger. The Note 8 with a 30% larger battery charges full in 1:40 or 100 mins. The iPhone 8+ too 200 mins with a smaller battery. What APple did, is they chose not to license Qualcomm's fast charge tech and made their own or found some cheap chinese company with inferior hardware to use.

Even when using the 30W charger? Damn that's pretty pathetic as my Moto Z Force takes a little over an hour to go from close to 0 to 100% and the battery is much larger than that of the iPhone 8.

Your claim is false. Fast charging batteries don't ruin them because they are designed to be fast charged. This has been repeated over and over again. You're being evil because you don't know what you are talking about. https://www.qualcomm.com/products/features/quick-charge/faq Q4: Can Quick Charge hurt my smartphone's battery? A: Quick Charge operates within the design parameters of batteries found in most smartphones. It is just charging the battery the way it is designed to be charged. Device manufacturers build smartphones with a specific battery that can accept a specific level of charge. The battery size and maximum current of each battery are design decisions made by the manufacturer and can vary from smartphone to smartphone, tablet to tablet and so on. However, traditional battery charging technology does not come close to the full power requirements of today's large batteries. Quick Charge is designed to allow device manufacturers to achieve the full rated capability of the batteries they choose while still meeting the performance and safety standards set by the battery manufacturer. Please explain why a manufacturer would include a feature that would break the device? Can you explain that? Would Ferrari put tires rated for speeds up too 80MPH for a car that goes 200MPH knowing you likely will do more than 80? Does that make sense to you?

Has been using that for years - no, batteries have not imploded in capacity. If Apple allows for higher power than 5W no problem, why not use up to 15 now with much newer batteries ? Does not see a problem there.

Why then I have to switch to 'fast charging' mode on my phone ? Use logic. BTW I guess even the battery a special for fast charging use.
