Candle-powered phone charger

The Stower Candle Charger, in addition to being a basic emergency stove, powers USB gadgets with fire: put a fuel canister under it and it'll transmute heatrons into juicetrons as described in the Codex Ifritanimus. One canister will charge a smartphone twice; actual wax candles will presumably not stretch so far.

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.
