Our Verdict
This heater plugs into your wall outlet and takes up zero floor space. It costs $26.40 and includes a remote, timer, and precise thermostat. That feature set at that price point is uncommon.
The 500W output warms spaces up to 100 sq ft. Use it at your desk or in a small personal office. It cannot heat a bedroom, living room, or any room larger than a small dorm space.
The missing overheat protection is worth noting. Most heaters at this price still include that safety feature. Plug this into a dedicated outlet and keep the vents clear.
This heater costs about $62 per year to run at typical use. A standard 1500W heater costs about $187 per year. For a personal desk heater, the low wattage works in your favor.
What We Like
- Wall-mount design plugs into your outlet and frees up all floor space with no cord to trip over
- Remote control lets you adjust the heat setting from across the room
- Thermostat shows exact degrees from 60°F to 90°F, not just low, medium, or high
- Timer lets you set auto on or auto off in 1-hour steps up to 12 hours
- At $26.40 and 500W, annual running costs are roughly $62, about one-third the cost of a 1500W heater
What Could Be Better
- No overheat protection listed, a standard safety feature found on most competing heaters
- Covers only 100 sq ft, well below the 150 to 300 sq ft range typical of heaters in this price class
- 500W output produces only about 1,700 BTU per hour, too low to raise temperature quickly in most rooms
- No oscillation means warm air stays concentrated in one fixed direction
- Wall-outlet mounting locks placement to wherever outlets are in your space, with no flexibility to reposition

Frequently Asked Questions
Common questions about 450W Mini Space Heater With Temperature Detection, Remote Wall Outlet Electric Space Heater as Seen on TV with Adjustable Thermostat and Timer and Led Display, Compact for Office Room RV (Smart-White)
How big of a room can this heater warm?
This heater covers up to 100 sq ft. That is about the size of a small home office or dorm room. It is not built for bedrooms, living rooms, or any space larger than 100 sq ft.
How much does it cost to run each month?
At 500W running 8 hours a day, it uses about 4 kWh per day. At the US average electricity rate of around $0.15 per kWh, that comes to roughly $18 per month during winter.
Does this heater turn off automatically?
The timer lets you set an auto shut-off from 1 to 12 hours. The thermostat also cycles the heater on and off to hold your target temperature. There is no listed automatic safety shutoff for overheating.
Can it plug into any standard wall outlet?
Yes. It works on any standard 110V US household outlet. The plug rotates 180 degrees to fit different outlet positions. Avoid using it on an outlet already loaded with other high-draw devices.
Is this safe to use in a bathroom?
The specifications list this for indoor dry use only. There is no water-resistance or GFCI rating listed. Use it in dry spaces like offices or dorm rooms, not in bathrooms or areas near moisture.
