H2O's patented technology uses two electrodes made of special alloys which, when immersed in water, trigger a chemical reaction producing electricity.

To maintain a constant supply of energy, simply refill the battery as the water evaporates - typically every two to three months.

The battery has a minimum continuous life of two years.

If you return your old battery to Tango Group, replacement batteries may be bought for £5 per pack of two.

All Tango H2O water-powered products are energy saving, better for the environment and money saving.
