Benson's list of leads is here
Having purchased a Lumia 950XL, which has "fast charging" rather than "quick charging", I have been looking for suitable chargers. I guess I am gonna have to stump up £20 for a USB-C charger. I would have preferred a 3 AMP charger with both USB-A and USB-C ports but thus far they look a tad iffy.
(BTW you cant "fast charge" using USB-A to USB-C)
