# Roll-Out Solar Chargers The HeLi-on Compact Solar Charger Features a Windup Solar Cell Mat By Michael Hemsworth | Published 2015-11-18 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/compact-solar References: [gearhungry](http://gearhungry.com/2015/11/heli-on-solar-charger.html) & [kickstarter](https://www.kickstarter.com/projects/infinitypv/heli-on) When it comes to [solar panel cells](https://www.trendhunter.com/trends/portable-solar-tracker), the more space that you are capturing sunlight on, the more energy you'll get, so the HeLi-on Compact Solar Charger is designed with a roll-out solar panel to obtain the highest level of energy possible. Featuring a design aesthetic that's focused on portability, the HeLi-on Compact Solar Charger has several inches of solar cells that roll out and roll back in without fuss. Aside from [directly charging your device](https://www.trendhunter.com/trends/kuxiu-k1), the HeLi-on Compact Solar Charger features a [built-in backup battery](https://www.trendhunter.com/trends/charger-2) that will provide additional charging capabilities when you aren't outdoors. When exposed to sunlight for just a few hours, the HeLi-on Compact Solar Charger will charge your device and/or its internal battery to make capturing the power of the sun easier than ever. ## Trend Insights (Trend Hunter) - Score: 6.1/10 - Popularity: 87% | Activity: 89% | 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) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Key Themes Behind This Trend - **Roll-out Solar Panels:** The trend of creating solar panels that can be easily rolled out and rolled back in, offers opportunities to increase the amount of energy captured and its portability. - **Portable Solar Chargers:** The trend of designing solar chargers with a focus on portability and built-in backup batteries offers opportunities for those who require an off-grid power source. - **Hybrid Solar Chargers:** The trend of creating solar chargers with built-in backup batteries allows for energy to be captured and stored for later use when solar power is not available. ### Where This Applies - **Outdoor Gear Industry:** The outdoor gear industry may explore roll-out solar panels as a disruptive innovation opportunity, as it aligns with the industry's focus on environmentally friendly solutions. - **Travel Industry:** The travel industry may explore portable solar chargers as a disruptive innovation opportunity, providing a reliable, off-grid power source for travelers on the go. - **Construction Industry:** The construction industry may explore hybrid solar chargers as a disruptive innovation opportunity, providing a reliable off-grid power source for job sites where traditional power sources are not readily available. ## Related on Trend Hunter - [Origami Travel Solar Panels](https://www.trendhunter.com/trends/solar-panel-origami-technology.md) - [Origami-Inspired Solar Panels](https://www.trendhunter.com/trends/sego-innovations.md) - [Origami-Inspired Solar Panels](https://www.trendhunter.com/trends/levante-origami-solar-panel.md) - [Folding Solar Power Panels](https://www.trendhunter.com/trends/dexpole-solar-power-bank.md) - [Rolling Technology Chargers](https://www.trendhunter.com/trends/freestyle-wireless-charger.md) - [Flexible Solar Film Energy](https://www.trendhunter.com/trends/heliafilm.md) - [Expandable Solar Power Banks](https://www.trendhunter.com/trends/deepsolar-x20-solar-power-bank.md) - [Device-Charging Sun Hats](https://www.trendhunter.com/trends/ecoflow-power-hat.md) - [Hybrid Portable Battery Chargers](https://www.trendhunter.com/trends/charger-2.md)
