TrendGear 2 in 1 Heater Fan Combo, 1500W Portable Space Heater with Adjustable Thermostat, Electric Cooling Fan with Oscillating, Overheat & Tip-Over Protection, Ideal for Home & Office Use

Why I reached for a 2-in-1

Between a drafty home office and a bedroom that runs warm in summer, I’ve learned to value compact devices that earn their keep year-round. TrendGear’s MK-3 promised a portable heater and a tabletop fan in one unit, with oscillation, safety shutoffs, and a small footprint. I’ve lived with it through late-winter cold snaps and a few muggy evenings. It’s not trying to replace a central system, but for targeted comfort at your desk or bedside, it has a lot going for it—along with a few quirks you should know about.

Design, size, and build

The MK-3 is compact and easy to place: about 8.2 x 10.2 x 13.9 inches and 4.6 pounds. It’s light enough to move one-handed, and the center of gravity is low enough that it doesn’t feel tippy on a nightstand. The plastic shell won’t win design awards, but it looks clean and a bit more refined than many budget space heaters. The front grille is dense, which helps diffuse airflow but does get warm in heat mode; you’ll want to keep it out of reach of curious fingers.

Controls are straightforward. Buttons under an indicator light let you toggle between low heat (750W), high heat (1500W), and fan-only. There’s an adjustable thermostat to set a target, though there’s no digital temperature readout or app control. The included remote mirrors the basics, which is handy at bedtime or when you’re tucked into a work chair.

Heating performance

For its size, the MK-3 heats efficiently. On high (1500W), it took my 12 x 12-foot office from chilly to comfortable in roughly 25–30 minutes, starting at around 65°F. Once the room was up to temperature, the thermostat cycled the heating element predictably, avoiding the “blast then freeze” swings you sometimes get with cheaper space heaters. In a larger bedroom (around 180 square feet), it still made a noticeable difference but took longer; it’s best suited as a spot heater or for genuinely small rooms.

Low heat (750W) is useful for maintaining comfort without overcooking a space. I used it to take the edge off a cold morning in a 10 x 10 nursery with the door cracked; it kept things steady without waking anyone with excessive fan noise.

Oscillation is limited to 55 degrees, which sounds narrow but was surprisingly effective at evening out the air in front of a desk or across half a bedroom. The sweep is smooth and quiet. If you need wall-to-wall coverage in a large room, you’ll want a wider oscillation or a second heat source; if your target is your side of the bed or a defined work area, the MK-3’s swing feels appropriate.

Fan mode and summer use

As a fan, the MK-3 is more about personal comfort than whole-room circulation. Its airflow is focused and gentle, particularly at a few feet away. On a warm night, it provided a soft, steady breeze with the kind of low, consistent white noise I like beside the bed. It will not replace a high-output tower fan, but it does enough to move air around your immediate area, especially with oscillation enabled. If your main goal is cooling a medium-size room, this won’t be your only fan.

Noise and everyday ergonomics

Noise levels are pleasantly low. On heat low or fan mode, it’s a soft, consistent hum you can easily talk over or watch TV with. High heat adds some airflow noise, but not the rattly whine you sometimes get from compact units. I measured informally with a phone app and it sat in the “quiet office” range at a few feet away. There’s no annoying click from the thermostat, and oscillation is almost silent.

The remote is a convenience—but it’s clearly an infrared design with a short range and strict line-of-sight. It worked best within about 8–10 feet and pointed squarely at the front grille. If you expect to bounce commands from odd angles, you’ll be disappointed. I mostly used it from bed or from my chair, and it did the job.

Safety and power considerations

The MK-3’s safety features behave as advertised. Tip the unit and it cuts power immediately; block the outlet and it shuts down rather than cook itself. These are must-haves for any space heater, and they give some peace of mind.

Be aware of power draw. At 1500 watts, the MK-3 pulls up to 12.5 amps on a standard 120V circuit. If you share an outlet with other high-draw devices (space heaters, hair dryers, vacuums) or run it on a long, light-duty extension cord, you’re asking for warm cords and tripped breakers. In my testing, the cord warmed noticeably on high when sharing a circuit. The simple solution: use a dedicated wall outlet, avoid power strips and extension cords, and don’t daisy-chain other heavy loads. This is standard advice for any 1500W heater, and it applies here.

Give it clearance—at least a couple of feet in front and above—and keep it off plush surfaces that could block the intake. The chassis stayed cool on the sides, but the front grille gets hot in heat mode, as expected.

Energy use and cost

At 1500W, expect about 1.5 kWh per hour. At an electricity rate of $0.15/kWh, that’s roughly $0.23 per hour on high, half that on low. The thermostat helps by cycling the element off once the room reaches your set point. If you’re trying to save on whole-home heating, using the MK-3 to heat only the room you’re in can make economic sense, especially in smaller spaces.

Maintenance

There’s no removable filter. I found that a quick pass with a vacuum brush on the intake and a microfiber wipe of the grille kept dust buildup at bay. As with most heaters, there’s a faint “new electronics” smell during the first hour or two of use; it dissipated quickly.

What I like

• Compact and easy to move; stable on a desk or nightstand
• Effective spot heating with useful low/high modes and thermostat cycling
• Quiet operation and smooth 55° oscillation
• Safety shutoffs (tip-over and overheat) work quickly
• Simple, no-fuss controls with a basic remote

What could be better

• Fan mode is gentle; not a replacement for a strong room fan
• Remote needs close, direct line-of-sight and has limited range
• 55° oscillation is effective but not wide; coverage is localized
• High power draw requires a dedicated outlet; the cord can get warm on high

The bottom line

The MK-3 shines as a personal comfort appliance: a compact heater that can make a small office, bedroom corner, or reading nook comfortable without roaring like a jet engine, with a summer-friendly fan mode that adds gentle air movement when you don’t need heat. Its strengths are straightforward performance, quiet operation, and practical safety features. The trade-offs are equally clear: fan-only mode is modest, the remote is finicky beyond a few yards, and like any 1500W heater it demands respect for circuit limits.

Recommendation: I recommend the TrendGear MK-3 if you need a portable, quiet spot heater with a bonus fan mode for year-round use, especially in small rooms or at a workstation. It’s an easy fit for desks and bedside stands and does a reliable job warming your immediate area. If you want whole-room cooling, ultra-wide oscillation, or you can’t dedicate a wall outlet to a 1500W appliance, you’ll want to look elsewhere. For targeted comfort and simple, safe operation, though, the MK-3 earns a spot in the toolkit.
