I have the 30W PD charger with 4 ports sharing 30W. I read it off the label.
1st phase is accept the reduction in recharge from the official supplied 45W charger. If that experience is good then get the 45W version when it is shipping. Cable consolidation matters a little more than charger consolidation, when you put it all together in a bag, the cables really add most of the bulk.
My preference is no more than 60W total power to keep the charger down in size and it prioritizes the sharing across ports, so e.g. can do 45W PD and shares 15W over other ports, or as my laptop gets near to fully charged, it's draw drops to say 30W then the other ports share 30W. I don't want to see huge chargers.
We'll be underwater by time Anker releases PD stuff, icecaps melted. I hope Anker moves further inland by then.
