The TEG12VDC -AIR has a peak rating of 30 watt . The forced air TEG Generator works up to a hot surface temperature of 400°C (750°F). A pipe vent should be used to allow cooler air to enter the of intake fan to maintain DT (Not Supplied).  The OUTPUT from the TEG is regulated with a Boost/Buck constant voltage/constant current DC to DC converter that can be adjusted from ~5V to 16V. This is ideal for trickle charge a 5v to 12VDC battery when set at 5V to ~14.2V based on charging specifications found on the battery label.  (OUTPUT BASED ON MAXIMUM HOT SIDE TEMPERATURE and DT).


  • If used for charging BATTERIES a diode is incorporated to prevent reverse voltage to TEG.
  • GENERATOR REQUIRES cold air on the fan side for best performance!
  • We STRONGLY advise a 2″or 3” tube air duct from outside that will draw cold air threw
  • The fan onto the heat sinks which provides two critical requirements!
    1. Creates critical DT that will increase and maintain optimum power generation.
    2. Protects the fan from overheating. The fan is rated for 160°F or 70°C maximum.
  • Do not exceed 750°F hot side temperature on the hot side or you will damage the TEG modules.
  • The controller is a boost /buck constant voltage/constant current charge controller.
  • It is set from the factory at 13.8V to 14.2V although you can set to any voltage with the screws on the side
  • marked CV (Constant Voltage) or CC (Constant Current) as well to meet you charging requirements.
  • The second smaller board is a buck board which controls fan speed. The pot in blue with brass screw
  • will control the fan speed which can be set with a screw driver.
  • We also recommend charging a battery and drawing loads (lights, motors, etc…) from the battery NOT
  • from the TEG output directly.
  • FAN: 5 inch (120mm) IP55 protection. 3 watt consumption at ideal tested speed
