I just got a 2018 iPad Pro 10.5" and am adjusting to USB-C. The problem is that everything I have is setup to charge Lightning to USB-A, as in I have 3 different Anker multiport chargers on my desk, none of which seems to be able to charge my new iPad. There are a lot of chargers out there, even just from Anker, my go-to brand.
What do you all use for a portable multi-port charger that can charge at least 4 devices (more is better), including your power-hungry iPad Pro?
I have this for travel and it works very well: https://satechi.net/collections/usb-type-c/products/75w-dual-type-c-pd-travel-charger
Do you want a wall charger or desktop charger? Or you want a power bank for travelling?
I have this for desktop and this for travel. Both will charge my 11" iPad Pro - the latter rather slowly, of course, but OK
I was looking for something that could go on my desktop. I think I gave up on my current Anker multiport too quickly. When I was plugging it in, nothing was happening, but I tried again and after about 4 seconds it started charging. It must be the charger negotiating the correct wattage/amperage/? I hope it means my other chargers will continue working as well.
I am using Anker as well and never had any issues. Since the iPad Pro can charge only up to 30W (it is slightly more, but only slightly), you don’t need the stronger chargers. So just pick once with enough ports and get some cables 
Looks like @ThatGuy & I both got the same Anker mains charger (https://www.amazon.co.uk/gp/product/B072K5SFHG). I’ve not got a iPad, I’ve been using mine to occasionally charge my MBP but mainly charge the battery pack I got: https://www.amazon.co.uk/gp/product/B06XQ19LWL which also has enough clout to charge the MBP.
Been very pleased with both devices.
