Ok, this is VERY interesting and was bound to happen sooner or later...
Think of it - your out 'in the wild' and what are your TWO primary concerns? Being 'geeky/techie' you want to keep your portable electronics charged - an endless stream of 'power stations' with Li/LFP storage is available as well as simple Li power bricks.
However, what about your food and drinks? Inexpensive 12V powered compressor fridge/freezers ARE available however the user needs to provide a power source for them.
What if the two devices were somehow 'married' or combined? A portable cooler/freezer that had its OWN LFP power storage?
While the user MAY still need to carry TWO devices (solar panel array + cooler/freezer) however it MAY free up valuable packing space for other gear. There still might be the possibility that ONLY the cooler/freezer/power-station need to be brought. :)
IMHO: sadly the combined product they are offering here is horribly overpriced as users could simply source individual parts and create their own 'package' for a mere fraction of what they are asking here, it does seem to be a good idea.
