Our take on the 400W Portable Desktop Electric Space Heater

A small 400W electric heater meant to sit on a desk, table or counter and warm a spot rather than a room. It uses a thermal wire element and a turbo fan, with a claimed 2-second heat-up and a 60dB noise level. It has overheat protection and a heat-resistant PP body, and at about 0.7 lbs it moves easily between rooms. Against full-size space heaters it trades room-wide output for portability and low power draw, so it suits close-range use in small spaces, not whole-room heating.

Best forDesk and tabletop use close to the bodySmall enclosed spots like a bathroom, kitchen or basement nookPeople who want to heat one area instead of the whole homeA low-power secondary heat source
Pros
  • Very light at about 0.7 lbs and small at 6.5 x 3.9 x 3.9 in
  • Fast warm-up claimed from the thermal wire and turbo fan
  • Overheat protection and heat-resistant body
  • Runs on 400W, low draw for a plug-in heater
  • Quiet design claimed not to disturb sleep or work
Cons
  • 400W output is modest; it warms a person or a small spot, not a room
  • Claimed 107.6 sq ft heating area overstates what 400W can do
  • 60dB is audible in a quiet room, not silent
  • Single power switch, no thermostat or timer shown
  • Short 39.4 in cord limits where it can sit

About the 400W Portable Desktop Electric Space Heater

This is a 400W portable desktop electric space heater for small spaces. It uses a thermal wire and a high-speed turbo fan to heat quickly, and its low-noise design is meant not to disturb sleep or work.

The housing is made of heat-resistant PP. Overheat protection shuts the unit off at 90°C (194°F). It has a rounded top, a vertical slatted grille at the front for air output, a horizontal slatted grille at the back for air intake, and a power switch on the back.

The heater is a compact single unit that can be carried from room to room and often fits on a table top. It suits small areas such as bathrooms, kitchens, basements and garages. Heating only the rooms in use lets you turn down a central thermostat.

Questions and answers

How much space will a 400W heater actually warm?
Expect spot warmth within a few feet, not full-room heating. The claimed 107.6 sq ft area is optimistic for 400W; treat it as a personal heater for a desk, counter or small enclosed nook.
Is it safe to leave on?
It has overheat protection and a heat-resistant PP body, and it shuts off at a stated 194°F. Still keep it clear of curtains, bedding and paper, and unplug it when you leave.
How loud is it?
The fan is rated at about 60dB, roughly the level of normal conversation. That is noticeable in a bedroom or office but not drowning out a TV.
Does it have a thermostat or remote?
No. The unit has a single power switch on the back and no adjustable thermostat, timer or remote, so you switch it on and off by hand.
What comes in the box?
One mini heater with its attached 39.4 in power cord and two-prong US plug. Nothing else is included.
Can I use it in a bathroom?
Only if it sits well away from water and splashes, since it is not described as water-resistant. A dry counter away from the sink or tub is the safer spot.
Where is the 400W Portable Desktop Electric Space Heater cheapest?
At Deal.ai, for $29.43, as of our latest check.
