Our Verdict

This heater costs $4.95. That price is extraordinary for any working space heater.

At 500W, it covers about 50 sq ft. That fits a desk corner, small bathroom, or personal workstation.

The brushless DC motor runs below 45 dB. You can use it while sleeping or on a video call.

The thermostat cycles power on and off. This keeps temperature steady without wasting electricity.

Tip-over protection shuts the unit off if it falls. Overheat protection is not confirmed in the specs.

This heater works best as a personal spot heater. Do not expect it to warm a full bedroom or living room.

What We Like

  • Costs only $4.95, making it one of the most affordable PTC ceramic heaters you can buy.
  • Operates below 45 dB using a brushless DC motor, so it stays quiet during work or sleep.
  • Weighs just 500g and measures 15x12x18cm, fitting easily on any desk, shelf, or countertop.
  • Heats up in 2 seconds using PTC ceramic technology for fast personal warmth.
  • Built-in thermostat cycles the unit on and off to hold your set temperature and reduce energy waste.

What Could Be Better

  • Only 500W output warms roughly 50 sq ft, far below the 150 sq ft typical of competing compact heaters.
  • Overheat protection is not confirmed in the product specifications, leaving a key safety feature unverified.
  • No timer means you cannot schedule automatic on or off times.
  • No remote control requires you to press buttons directly on the unit.
  • No oscillation limits heat to one fixed direction, unlike many competing models that spread warmth across a room.
