Most propane heaters do one thing: burn fuel and release heat. The BlazOn EMBER does something fundamentally different — it turns that heat into electricity, then uses that electricity to power its own fan and keep a USB port live for device charging. No batteries. No cords. Just heat doing double duty.
What Is Thermoelectric Generation?
Thermoelectric generation converts a temperature difference directly into electrical energy — a phenomenon known as the Seebeck effect, discovered in 1821. When two conductive materials are joined at two points, one hot and one cool, a voltage is produced that drives an electric current. The greater the temperature difference, the more electricity is generated.
In a thermoelectric generator (TEG), semiconductor materials are sandwiched between two ceramic plates. One plate faces the heat source; the other stays cool by exposure to ambient air. That temperature gradient produces a continuous electrical output with no moving parts, no combustion, and no battery — just physics.
How the EMBER Puts Thermoelectric Generation to Work
The EMBER integrates a TEG module positioned to capture heat from the propane burner. As the flame runs, the hot side heats up while the cool side dissipates to the surrounding air. That steady gradient generates continuous low-voltage DC electricity, routed into two functions:
1. Powering the forced-air fan. Unlike radiant heaters that only warm what's directly in front of them, the EMBER's fan actively pushes warm air throughout the space. That fan runs entirely on thermoelectrically generated power — no batteries, no wall outlet. The hotter the flame, the stronger the airflow.
2. Keeping a USB port live for device charging. The EMBER's built-in USB port draws from the same thermoelectric output. In a power outage, when your phone is your only connection to emergency services and weather alerts, that USB port matters. The EMBER doesn't just heat the room — it keeps you connected.
Why This Matters in Real-World Situations
Off-grid use: RVing, boating, or cabin camping with no shore power? The EMBER needs only a propane tank. Fan, USB, heat — all running without any external electricity.
Power outages: The EMBER provides continuous heat and USB charging for as long as propane lasts — hours from a 1 lb canister, much longer from a larger tank.
Zero maintenance: Thermoelectric modules have no moving parts and are rated for tens of thousands of hours. Once the EMBER is running, power generation is completely automatic.

The Science in Seven Steps
1. The propane burner ignites and produces a steady flame.
2. Heat conducts into the hot side of the thermoelectric module.
3. The cool side releases heat to the surrounding air.
4. The temperature difference drives electron movement through the semiconductor.
5. That electron movement is electricity — routed to the fan motor and USB port.
6. The fan pushes warm air through the unit and distributes heat evenly.
7. The USB port delivers continuous power for phones and small devices.
More Than Just Heat
Most portable heaters are single-purpose devices. The EMBER is built on a different premise: in the moments you need portable heat most — power outages, off-grid living, cold-weather emergencies — you also need power. Thermoelectric generation makes both possible from a single propane tank, with no batteries, no cords, and no additional fuel source.
That's not a feature. It's physics — engineered into a product built for the moments that matter most.
