Although this power cube looks a bit like an extremely uncomfortable recliner it is actually a portable solar generator. I am assuming when they claim that it is portable they are using the term very loosely, because this isn't exactly something you toss in the car and go.
This portable cube weighs a whopping 2,000lbs so its not quite something you lift on your own. Perhaps when they say portable they mean store it in your garage then drag it out when needed. It is a bit more portable than a fixed solar panel.
The cube has 200 watt solar panels, 3500 watts of continuous inverter output and 2400 amp hours battery storage. So in the event of a power outage you'll be better off than your neighbors.
