From the Manufacturer

Instant charging power anytime, anywhere

The Candle Charger is a safe, miniature power plant that provides on-demand electricity when the grid can't. It's power we control, anywhere we need it - indoors or out, day or night, grid or no grid.

Indoor charging anytime

When power outages hit, staying connected to family, friends, and emergency services is critical. But how to keep charged? - Batteries store power - they don't make it - We love solar, but it doesn't work at night or indoors - Hand cranks produce minimal power. 10 hours cranking to charge a phone? That's tough. We want a reliable solution, and the Candle Charger is the first indoor generator designed to charge smartphones and keep them charged.

Smartphones are amazing machines: Stower chargers keep these powered when the grid can't. Whether it is someone a US National Park, or in their home during a blackout, or far from the power grid where energy is not available, we want to bring sustainable energy to everyone in any situations. Energy empowers people and Stower believes that sustainable power should be a right for everyone.
