The H2O 8 digit water powered calculator uses the latest long life H2O technology to power this compact 8-digit calculator.

Simply add water to the cell to activate, and enjoy free energy to run your calculator. Add water when required, typically every 3 to 6 months. At the end of the life of the cell – usually 2 to 3 years, the cell can be replaced, and you can start over again.

The calculator is made from biodegradable plastic, so is environmentally friendly and easily recycled.

Dimensions : 11 x 6.5 cm
