Can you expand on that argument? I believe you are saying that because chargers are getting so good there is less need for portable charger?
I'm also not sure it is a deliberate change, the market dictates.
There is a huge section of the laptop market moving from proprietary chargers with 19V with 60W typically to shift to open USB-PD which in turn opens up both USB-PD chargers and USB-PD portable chargers. We're seeing this with Apple and Google.
There is also a gap in solar panels which output USB-PD, so take for example the 21W solar panel you just won it is two 2A port but one USB-PD would then recharge laptop.
The whole area of USB-PD in the 60W region is vastly under representative in Anker portfolio.
There is a generational shift from use of cars to bike, train, and living less in the home, leaving home with a kind of laptop and needing fast small chargers and portable charger.
Also we need USB-PD rechargeable skateboards.
