Fast Charging: which charger ?

Question

Fast Charging: which charger ?

So in Technical Specs we find that fast charging to a full charge can be accomplished, (depending on factors) at 30 minutes. However in the fine print, we cannot decipher which charger is needed:

Testing conducted by Apple in August 2017 using preproduction iPhone X units and software and accessory Apple USB-C Power Adapters (29W Model A1540, 61W Model A1718, 87W Model A1719). Fast-charge testing conducted with drained iPhone units. Charge time varies with environmental factors; actual results will vary.

Have tests been done to confirm which charger, 29W-61W-87W, accomplishes this? It would appear that any/all of them would accomplish this fast charge. Don't know that I can make the purchase until I get the correct one.

iPhone X, iOS 11.1.1, null

Not at all. See the following from Fast charge your iPhone X, iPhone 8, or iPhone 8 Plus - Apple Support

Your iPhone fast charges up to 50 percent in 30 minutes when you use an Apple USB-C to Lightning cable and one of these adapters:

Apple 29W, 61W, or 87W USB-C Power Adapter

A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)

Obviously you are not very busy with extremely important things to do! 😉

Thanks FoxFifth, I hadn't seen that reference. So that leaves me guessing that devices that need more power, such as an iPad and a MacBook are more appropriate for the larger chargers. Thanks Again
