World's fastest external phone charger developed

Researchers have invented the world's 'fastest' external phone charger which ends the need to plug your smartphone into a wall electricity socket and can charge your device in just 15 minutes.

The Petalite Flux battery, created by Leigh Purnell, an Aston University graduate, can charge itself from empty to full in 15 minutes.

The device, small enough to fit in the pocket or bag, eradicates the need to plug your phone into a wall electricity socket or computer USB slot.

When the phone needs charging, users can simply connect it to the Flux battery and continue with their day.

In 2014, Purnell established Petalite Battery Systems with the intention of creating the world's fastest charging external battery.

The Flux battery will soon be launched on the Indiegogo crowdfunding website.
