Solar box cookers typically cook food at temperatures in the 100 - 175 °C (212 - 347 °F) range. Depending on their size, this type of solar cooker can accommodate multiple pots simultaneously. The sides and bottom are insulated to retain cooking heat. Worldwide, they are the most widespread. There are several hundred thousand in India alone.
