This fantastic design comes from great designer. The designer explains that a normal fridge consumes over 21% of the total energy in an apartment, which is an impressive figure. These small fridges can be connected to a power supply, get fully charged and the cool off your food for hours to come without consuming anymore energy. Also, if you happen to have small quantities of food or groceries, it is not necessary to power-up all the cooling cases, but just one or two. This would not be possible with a normal fridge. Portability is also a strong feature. You can just place the items anywhere you like, without worrying about occupying a lot of space.
And just look at their amazing shape!
