## About

Based in Lagos, Nigeria, and founded in 2018, Koolboks Limited manufacture solar refrigerators by combining the natural forces of the sun and water. In September 2025, Koolboks raised USD 11 million in Series A funding, co-led by returning investors KawiSafi Ventures and Aruwa Capital Management. The company offers a solar-powered freezer, with pay – as - you - go (PAYGO) device installed in it. Additionally, it comes with two led bulbs and two USB ports for mobile charging. Furthermore, the firm product offers refrigeration for up to 4 days even without light and solar power as it stores the energy in the form of ice batteries with integrated lithium-ion batteries. Apart from this, the product acts as a refrigerator, cold storage, or freezer for perishables and beverages depending upon the preference of its user. The company will use the funding to accelerate manufacturing, distribution, and adoption of its solar-powered cold storage technology across Africa and beyond.
