No we don't.
I am aware of the niche needs of those with breathing difficulties, but in all other cases the need for AC 115V power is better met with changing the device.
So take a 10" tablet with USB needs, rather than laptop with 115V AC needs.
This week I travelled with my 26800 Powercore. If I were just with my phone, I'd get ~ week's power, if I were with a phone and tablet, say 3-4 days power. The 26800 is the maximum you carry on most flights no questions asked, I got the 26800 out to charge my phone and as the airline's in-seat power was not working the passenger next to me asked to use also. No problem.
Powerhouse 200, would likely be not used ever. At home, I have a UPS which is heavy but most cost effective than Powerhouse. When on the road and power constrained I take different devices altogether. The Chromebook with 115V AC input does not leave the house, the tablet with USB-C does.
