There was a multi port PD thing at Anker booth at CES but details scsnt.
Where you're at now is my next logical step, my laptop has been repaired twice but is next due for retirement and then I'd get something like the Flip. Then that would cause me to want a PD Powercore and then a Powerport which can recharge the Laptop and the Powercore PD at the same time from one socket.
What I want is a 60W dual port PD which gives 60W to one port or if two ports used they share 60W. I'd want one or two TypeA Potts for legacy devices such as Soundbuds.
