My link to source and pertinent quotes from Anker CEO Steven Yang.
"This year, we announced that the dual-port product would increase to 65 watt or up to 90 watt. We feel that is enough for now, but looking forward to the future, we feel the multi-port product will probably have to be 150-watt or 200-watt or even 250-watt — because the multi-port product will have to support, for example, a 60-watt phone or a 120-watt laptop and a few other things that will quickly add up to 200 watts. At this power rating, it really needs gallium nitride to reduce the size of that charger.
Those huge brick adapters that come with gaming laptops were 200 watts, right? Users don’t want to carry that 200-watt brick everywhere. With gallium nitride, we can make a 200-watt charger in a very small fraction of that size."
So I would expect two phases:
- per-port max of 140W, across all ports 100W-140W-150W type initially as very few need more than that (per port)
- going to 200W later.
This is based purely on two things - Mr Yang’s own words and if you read what others are doing similar things around similar timescale. I won’t link to the latter.
Please bear in mind what going above 100W per port actually means. Your existing cables won’t work. 100W is 20V 5A. But to drive a port above 100W needs a different cable to USB PD 3.1.
So expect new cables to support > 100W as without those cables you cannot then take the next step to >100W per port
So again I am thinking initially a per-port 100W-140W, and new cables to support higher Voltage (to then support higher Wattage) in a multi-port package (say a 100W port but multi-port total higher) and then 2nd phase where per-port is above 140W and total raises even higher.
Personally I am still hanging back. I recently got a new laptop, takes 45W but it has decent DC buck-boost converter within and is happy ingesting 10W, it runs average 4W, consistent with it’s 11 hours battery life, so I actually bought in the last Prime sale the 12W output Powercore 26800 for £40, which is a 6 year old design, and the 4-port desk 65W charger, which is a 2 year old design, which has a 45W port for £30
I bought those with a reasonable insight of what is next, and their prices…
