Uniross has launched a battery charger that can completely recharge AA and AAA batteries in just 15 minutes, apparently making it officially the world's fastest battery charger.

A charger with its own "computerised brain", it has a safety feature to cut the charger out if batteries are left in for over 20 minutes, whilst still keeping them topped up with power.

There's also a built-in fan that keeps the batteries cool, and it comes complete with an adapter which allows it to be used from a car cigarette lighter.

The new high speed Uniross charger will be available from October for £34.99.
