The tiny device easily fits on a keychain, and when attached to AA, C, or D batteries it can convert that into usable power for smartphones. Flintu's founders invented the clever little gadget after having their smartphones die while on a [backpacking trip](https://www.trendhunter.com/trends/snow-peak-gigapower-battery). In a pinch, they managed to rig together a charger using normal batteries, and that concept has transitioned into the productionized device currently on offer. The Flintu SideKick is currently taking funding on [Kickstarter](https://www.trendhunter.com/trends/k-smart-keychain), where it's already reached its more than doubled its goal of $30,000 at the time of writing. ## Trend Insights (Trend Hunter) - Score: 5.8/10 - Popularity: 83% | Activity: 84% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### Why This Trend Is Growing - **Rechargeable Batteries:** Disruptive innovation opportunity: Develop more efficient and longer-lasting rechargeable batteries for smartphones. - **Portable Charging Solutions:** Disruptive innovation opportunity: Create innovative portable chargers that are compact, lightweight, and versatile for on-the-go use. - **Alternative Power Sources:** Disruptive innovation opportunity: Explore alternative power sources, such as kinetic or solar energy, to provide sustainable and renewable charging options for smartphones. ### Industries Being Reshaped - **Consumer Electronics:** Disruptive innovation opportunity: Introduce new technologies and design concepts to enhance the functionality and convenience of consumer electronic devices. - **Battery Manufacturing:** Disruptive innovation opportunity: Improve battery manufacturing processes to increase energy efficiency and reduce waste. - **Crowdfunding Platforms:** Disruptive innovation opportunity: Develop user-friendly and secure crowdfunding platforms that empower entrepreneurs to bring their innovative product ideas to market. ## Related on Trend Hunter - [Feature-Packed Key Chain Chargers](https://www.trendhunter.com/trends/high-six.md) - [Grip-Enhancing Smartphone Batteries](https://www.trendhunter.com/trends/popsockets-popgrip-jumpstart-lightning.md) - [Card-Sized Powerbank Flashlights](https://www.trendhunter.com/trends/powerbank-flashlight.md) - [Micro-Sized Smartwatch Chargers](https://www.trendhunter.com/trends/keychain-apple-watch-charger.md) - [Compact Pill-Shaped Power Banks](https://www.trendhunter.com/trends/portable-capsule-power-bank.md) - [Illuminating Magnetic Smartphone Batteries](https://www.trendhunter.com/trends/moonside-maglight.md) - [Kinetic-Friendly Power Banks](https://www.trendhunter.com/trends/last-resort-power-bank.md) - [Ultra-Compact Tech Chargers](https://www.trendhunter.com/trends/nimble-champ-pro-portable-charger.md) - [Patch-Style Smartphone Power Packs](https://www.trendhunter.com/trends/battery-pods.md)
