The BBC has been given an exclusive look at a new kind of battery charger that can recharge a modern smartphone in less time than it takes to boil a kettle.
The technology has been developed by Israeli start-up Storedot.
The company's chief executive, Doron Myersdorf, showed the BBC's Leo Kelion how a smartphone could be recharged from being nearly out-of-juice to full capacity in a short space of time.
