Mobile phone charger that runs on water invented for 'people who spend time away from the electricity grid'

The invention works with any device that has a USB port and with almost any type of water, including salt water. It can even run on puddle water providing it isn’t thickened with mud or any other sediment.

The product was first glimpsed last year at the Mobile World Congress in Barcelona, but a modified version of the technology has been on show at Consumer Electronics Show (CES) in Las Vegas.

It is scheduled to hit the European market in May or June with a recommended price of 199 euros (£165), with replacement sodium cells costing around two euros (£1.60).

A Swedish company has invented a charger for mobile phones, cameras and GPS devices that can power-up your electronic gadgets with little more than water.

The charger needs just a tablespoon of water to produce around 10 hours of phone battery life.

It works via a chemical reaction. The water reacts with PowerTrekk’s special ingredient, sodium silicide, to produce hydrogen gas.
