USB-PD charged devices are getting a lot more common (Apple laptops from the last few years, larger power banks, Pixels, the upcoming iPad, etc)
USB-C charger clutter is real. The Anker 4-6 port USB-A chargers are great, but 10W/port only goes so far. Anker needs to offer a multi-port USB-PD charger.
My thoughts on specs:
2 ports - at least 45W Each (Macbook Pro, large power banks, etc)
2 ports - at least 18W each (Pixel, iPad, etc)
4+ 45W+ ports would be ideal, but 2x45W and 2x18W might be more realistic from a cost / size / heat POV.
