The Power Box Solar Oven is a box solar cooker invented by Matteo Magnani. It is made of laminated wood and has glass above and as the front wall of the cooking chamber. The cooker makes use of four mirrors (three above and one in front), which allows a great deal of light to be directed into the cooking chamber especially in the early morning hours and during the winter when the sun is low in the sky. Internally it uses a thermal mass of iron that has been painted black, which houses pots of different sizes.

Thanks to its wooden structure, internal insulation made of aluminum-coated cardboard, and its thermal mass, the Power Box Solar Oven is able to reach a temperature of 150 °C (302 °F) in 35-40 minutes and maintain this temperature during all phases of cooking. The system has also been designed to be very compact and easily transportable.

So far, cooking tests were carried out on cakes, bread and jams. With regard to the jams, more load quantities have been tied, up to a maximum of 2.6 kg (5.7 lbs) of fruit. Boiling temperatures have always reached, specifically 102 °C (216 °F), with temperature of the thermal mass of 121 °C (250 °F).
