The non-geeks in my home have Fusion 5000 as their bedside chargers so a power outage begins with 5000mAh of stored energy outside of their phone. They then have some Eufy stick-on lights to not stump their toes til they get to the LC40 / 90 / 130 dotted around. Then there is about 100Ah of Powercore to keep going for a few days, some solar panels to stretch that longer if its sunny. The laptops have fairly beefy batteries to begin using before we dip into phones then Fusion then Powercore then solar. If its sunny I can get about 100Wh per day from solar, that is enough for phones easily or tablets if its sustained sunny.
The biggest benefit of these Powerhouse is the AC port which implies a power hunger laptop which implies a 40Wh type battery which lasts a few hours and so 200Wh will last 4-5 days max.
The situation of camping, well if you're car-camping you'd run the car and a 12V DC/AC inverter. If you're not with a car, so carrying, you'd not be with a laptop but a phone or at most a tablet and then a Powercore 26800 typically.
So the decision tree here to go with a Powerhouse is baffling, I can only imagine either someone needing AC-only medical devices, or rich geeks who bafflingly cannot move to a 2018 USB laptop.
