A portable power bank that uses salt and water to recharge smartphones is on show at the Mobile World Congress tech show in Barcelona.

The Jaq charger never needs plugging in because it uses disposable cartridges to generate power.

The BBC”s Chris Foxx asked the company”s chief executive Bjorn Westerholm whether this was any better for the environment than using normal battery-based power banks.
