The new H2O desktop calculator runs on a revolutionary water-powered battery, offering an ecological alternative to conventional batteries. To maintain a constant supply of energy, the water battery simply needs to be refilled every two to three months as the water evaporates.

Every year, billions of conventional dry cell batteries are used and discarded, resulting in environmental pollution and costly disposal or recycling costs.
The H2O water battery has a life of at least 2 years, and unlike normal batteries can be left out to dry and then stored indefinitely. All components of the H2O battery are recyclable. The H2O calculator is suitable for use in all light conditions and has a large 12-digit display. The product measures 104 x 170 x 25mm and weighs 110g.
