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 crowd-funding website.
Recently, a new battery pack (also commonly referred to as a power-bank) was claimed to charge-up sufficiently in 15 minutes to be able to recharge most smartphones completely. Made by UNU Electronics, the Ultrapak Portable Battery Pack Series is claimed to gain 2000mAh of power with just 15 minutes of charging.
UNU had introduced the new Ultrapak series last month. The Ultrapak Go and the Ultrapak Tour by the company uses the Ultra-X charging technology that supposedly recharges up to 8x faster than conventional batteries thus resulting in a 2000mAh recharge in about 15 minutes. Users can then connect the power-bank to normally charge their smartphones or tablets.
The Ultrapak Go comes with 3000mAh battery capacity which can be fully charged in about 30 minutes of time. The power-bank is priced at $59.99 (approximately Rs. 3,600) and is available on company's store. The 10000mAh large battery capacity power-bank Ultrapak Tour requires approximately 100 minutes to fully charge. The power-bank on its store is priced at $99.99 (approximately Rs. 6,000).
