Designed by Zheming Zhou, the 'Double E' power bank works by incorporating an internal unit that can be shaken to create a charge that will power your phone. It's also chargeable via Micro USB, which means you can charge it through a traditional USB port and only use the kinetic charging capabilities if you find yourself without access to power outlets. The 'Double E' kinetic energy power banks feature [two USB ports](https://www.trendhunter.com/trends/kuxiu-k1-ultra) and even an [LED matrix display](https://www.trendhunter.com/trends/magink) that will let you know how much percentage is left on the unit's charge. ## Trend Insights (Trend Hunter) - Score: 6.2/10 - Popularity: 86% | Activity: 93% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Why This Trend Is Growing - **Kinetic Energy Power Banks:** Opportunity for disruptive innovation in the portable power bank industry by incorporating kinetic energy charging capabilities. - **Micro USB Charging:** Disruptive innovation opportunity in the charging technology industry by providing a convenient alternative to traditional power outlets. - **LED Matrix Displays:** Opportunity for disruptive innovation in the display technology industry by incorporating LED matrix displays into power banks. ### Industries Being Reshaped - **Portable Power Banks:** Opportunity for disruptive innovation in the portable power bank industry by incorporating kinetic energy charging capabilities. - **Charging Technology:** Disruptive innovation opportunity in the charging technology industry by providing a convenient alternative to traditional power outlets. - **Display Technology:** Opportunity for disruptive innovation in the display technology industry by incorporating LED matrix displays into power banks. ## Related on Trend Hunter - [Power-Providing Smartphone Stands](https://www.trendhunter.com/trends/solove-power-bank.md) - [Outdoor Lifestyle Power Banks](https://www.trendhunter.com/trends/sharge-power-bank.md) - [Magnetic Display-Equipped Power Banks](https://www.trendhunter.com/trends/supermini-go.md) - [Display-Equipped Power Banks](https://www.trendhunter.com/trends/pdgo-power-bank.md) - [Stand-Equipped Smartphone Batteries](https://www.trendhunter.com/trends/strickers-magsafe-power-bank.md) - [Solid-Liquid Power Banks](https://www.trendhunter.com/trends/kuxiu-s3.md) - [Wearable Triangular Power Banks](https://www.trendhunter.com/trends/mchaos-power-bank.md) - [Frozen Treat Power Banks](https://www.trendhunter.com/trends/popsic-charger.md) - [Literally Designed Power Banks](https://www.trendhunter.com/trends/duracell-power-bank.md)
