Our Verdict
This heater is a personal spot warmer, not a room heater. At 400W, it covers about 40 square feet. That fits a desk, bedside table, or small reading chair.
It heats up in 2 seconds. It runs at just 35dB. Those two features make it a strong pick for quiet, personal use.
Both tip-over and overheat protection are built in. You get those key safety features for only $19.99. That combination is rare at this price.
There are no controls beyond on and off. No thermostat, no timer, no remote. You trade convenience for simplicity and a very low cost.
This heater works when you need warmth for yourself, not for a room. It fits on any desk, moves easily, and stays quiet while it runs.
What We Like
- Heats up in 2 seconds at 400W output
- Weighs just 0.8 lb and fits in one hand for easy carrying
- Runs at only 35dB, quieter than most competing personal heaters
- Both tip-over and overheat protection are built in
- Costs only $19.99, one of the lowest prices for a safety-equipped personal heater
What Could Be Better
- Only 400W warms about 40 sq ft, far below the 150-300 sq ft range most competing heaters cover
- No thermostat means you cannot set or hold a target temperature
- No timer, so you must turn the heater on and off by hand
- No oscillation means heat travels only in one fixed direction
- The 37.4-inch power cord is shorter than the 5-6 foot cords found on most competing models

How big of a space can this heater warm?

Can I use this heater for camping?
The product specs list this for indoor use only. You can use it inside a tent or cabin that has a power outlet, but it is not rated for open outdoor conditions.
Does this heater have a timer or thermostat?
