How Kool Works
Koolboks freezers do more than just cool—they keep your devices powered, even during blackouts, reducing waste and boosting sales.
Take Iya Ibadan: Before her Koolboks, power outages meant spoiled food, low and lost sales. Now, her Koolboks freezer keeps everything fresh, sales up, and worries down!
Iya Ibadan bought a 538L maxi fridge for her frozen food business, Ijora Market, in Lagos, Nigeria. She no longer worries about food waste or power outages because of her Koolboks fridge
Light, Energy, Refrigeration
Koolboks created an affordable off-grid solution that can generate continuous refrigeration for up to 4 days, even in the absence of power and limited sunlight. This is due to our cutting-edge technology that lets us store energy in the form of ice as well as in batteries.
Our products can function as a refrigerator or as a freezer. It can also provide lighting for households and shops and electricity to power your electronics, all of which can work in off-grid areas.
It comes with 2 LED lighting bulbs and USB ports for charging mobile phones.
No one should be deprived of refrigeration because of cost.
Koolboks with its innovative embedded paygo technology is able to offer distributors the opportunity to be able to offer the Koolhome freezers on a lease to own to their customers.
Thanks to Koolboks, individuals and shop owners are able to pay in small monthly or weekly installments to own a solar refrigerator.
Koolboks is currently integrated with Aganza, Paygee and Solaris.

Energy Storage
We created Ice compartments in the refrigerator cabinets, so during the daytime, when the sun is available, which is often the case in Africa, Ice is made in these compartments, and at night, when the sun is no longer available, energy switches internally to the ice, maintaining the temperature of the cabinet till the next day when the sun is available again.
Thanks to this technology we've been able to bring down the cost of owning an offgrid solar refrigerator by close to 40%.
Koolboks compliment Ice batteries with integrated Lithium-ion batteries.
The lithium batteries are integrated in the freezer giving you a single compact system devoid of messy cables.
Lithium batteries provide an ideal solution for renewable energy storage. Their chemistry is often superior to its alternative chemistries, such as lead batteries.
Lithium-ion batteries have high energy density, low maintenance, performance and longevity, and versatility.
