H2O Power Water Calculator 12 Digits Ecological

Calculate conveniently and in harmony with nature! The H2O desktop calculator is a revolutionary device that requires only... clean water to work! Forget about purchasing and disposing of batteries or lighting restrictions for solar calculators.

Designed by Tango Group, this 12-digit calculator uses patented H2O water-activated battery technology. This is a breakthrough, ecological solution for an everyday product at home and in the office, offering reliable operation in all conditions.

Main Benefits of the H2O Calculator:

• Ecological Power Supply: Runs on water, eliminating the need to use traditional batteries containing harmful substances. H2O battery components are recyclable.
• Saving Money: No need to buy and replace batteries regularly.
• Reliability in All Conditions: Unlike solar calculators, it works without problems in any lighting, even poor - no more dimming display.
• Long-lasting operation: One filling with water is enough for about 2-3 months of continuous operation. The minimum service life of the H2O cell itself is at least 2 years.
• Convenient Storage: The H2O cell can be stored dry indefinitely, extending its potential lifespan.
• Full Functionality: A large, 12-digit display and ergonomic keyboard ensure comfort of use and access to the necessary functions.
• Easy Cell Replacement: When the H2O cell reaches the end of its lifespan (display dimming), it can be easily replaced with a new one.

Revolutionary Water Power (H2O Battery):

The secret lies in the patented H2O cell technology. It uses an electrochemical reaction between specially developed metal alloys and ordinary water, thus generating safe electricity needed to power the calculator. This process is completely clean and environmentally friendly.

Desk Calculator functionality:

• Large, clear 12-digit LCD display.
• Ergonomically designed keyboard for easy data entry.
• Provides all the standard features required for home and professional use, including:
  • Basic arithmetic operations (+, -, x, /)
  • Memory functions (M+, M-, MRC)
  • Calculating percentages (%)
  • Square root (√)
  • Change sign (+/-)
  • Erase functions (C/CE)

Easy Activation and Use:

To ensure constant power supply, it is enough to periodically (approximately every 2-3 months or when the display starts to dim) top up a small amount of water in the H2O cell, according to the attached instructions (usually through a dedicated hole). The calculator is ready for use almost immediately after activation with water.

Technical Specification:
