Computex: 3-in-1 Portable Power Device Wins Top Award

Designers have tapped into two fundamental concerns of the modern human—running out of power for your smartphone and lacking the right cable to charge it up.

An innovative power bank, slightly larger than a tube of lipstick, with an elegant 3-in-1 charge & sync cable, has won the 2012 Computex Best Choice Award, the highest honor presented at Computex Taipei, the largest ICT trade show in Asia.

The PocketCell rechargeable battery bank from Delta Electronics’ consumer brand Innergie can provide extended power to over 10 000 Portable USB-powered devices, such as iPads, iPhones, iPods, HTC, Samsung, and BlackBerry, Android smart phones, media players, and others. The battery bank comes in a stylish one-piece design with an elegant piano-lacquer finish.

According to P. S. Tang, a senior director of Innergie, the PocketCell packs a 3000 mAh rechargeable battery bank into its 72 gram frame, and can extend an iPhone’s talk time to more than 25 hours. It's chipset can figure out what kind of device its recharging power is coming from through the  2.1 amp fast-charging USB port and adjust how the power flows.

“To well protect precise components of mobile devices, there are built-in power protection systems, which offer over current protection, over voltage protection, overheating protection, over power protection, and short circuit protection,” Emilie Yeh of Delta Electronics’ spokesperson said.

Now that recorded sound has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it’s an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week.

Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison’s phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
