Candle Power — Charge a phone (or other device) with a candle? It can be done with this product, the Candle Charger from FlameStower, which uses heat from a candle or lighted Sterno can and converts it into power. You plug into the device with a USB cord.
On top, a tiny pot of water heats up and boils with the extra heat, making for a multiuse product perfect in emergency situations, in a camp, or off-grid. The company claims this unit can fully charge a smartphone twice from a single Sterno canister. ($75; May 2015)
