A hydrogen-powered calculator!? Amazing stuff. This product is eco-friendly, provides free energy, and has a replaceable H2O cell.

  • Environmentally friendly
  • Innovative
  • Long-lasting

The great thing about an H20 battery is that each component is recyclable, unlike conventional dry-cell batteries. Usually, the recycling of such dry cell batteries is not just expensive, it is incomplete which results in pollution and damage to our environment.
