Our Verdict

This is a 12V DC component heater, not a plug-in home appliance. You need a car battery or a separate DC power supply to run it.

At 100W, it puts out about 341 BTU per hour. Most home space heaters produce 5,000 BTU or more. This product heats roughly 50 to 75 square feet.

The thermostat reduces power as the space warms. That saves energy but does not replace missing safety features. There is no tip-over shutoff and no overheat protection.

At $20.02, it works as a heating module for cars or DIY builds. It is not a standalone room heater. Buy it only for a specific 12V project.

What We Like

  • Costs only $20.02, making it one of the most affordable PTC ceramic heaters available
  • Runs on 12V DC power, so it connects directly to a car battery or DC power adapter
  • Built-in thermostat reduces power draw as temperature rises, cutting energy use automatically
  • Tiny 2.4 x 1.7 x 2.4 inch body fits in very tight spaces and small enclosures
  • Heat-resistant silicone wire handles high temperatures for reliable electrical connections

What Could Be Better

  • Only 100W output, far below the 1,500W standard for home space heaters
  • No tip-over protection shutoff, a basic safety feature found on most space heaters
  • No overheat protection, a safety shutoff included on nearly all consumer space heaters
  • Requires 12V DC power and cannot plug into a standard 120V household wall outlet
  • No timer, oscillation, or remote control, all features common in comparable heaters
