About time something like this came to the market; the solar cooler does exactly what the name implies. It relies on energy from sun to keep it’s contents cool so you may very well term it as your portable refrigerator, one which runs on solar energy.
The gadget measures 41x36x43 cm and weighs about 25 kg. Despite the refrigeration system, the interior space still measures up to 40 liters and since you don’t need ice for this gadget; all the space is available for your contents that need to be kept cool. As expected, the design is pretty user friendly; it comes with handles which allow ease of carrying, has a rugged finish and design to make it more durable and able to survive parties. It also has the option of installing beach wheels which will make your life even easier. On the side, you will find two outlets; USB and 12 V and these can be used to either charge a phone or maybe use a blender. The inside lid comes with light so you need not worry about how to find something if its dark.
The design looks simple and quite easy to manufacture. However, that is not the case. To achieve this simplicity, the designers had to really put in some hard work and achieve this balance of size and power. The task was not easy and required some bulk of research and tests. The whole process of collecting solar energy, transferring it to batteries and then powering the refrigeration system had to be seamless and they have finally achieved the desired goal.
