Review · Tabletop ceramic
A small heater that publishes the two features small heaters usually omit — which is most of the reason to consider it.

The Lasko Ellipse CD12950 is a 1,500 W tabletop ceramic heater with wide oscillation, a digital display and thermostat, an AutoECO mode, a remote, a tip-over switch and a child lock. It draws 12.5 A and covers about 150 sq ft at standard sizing assumptions.
Small and tabletop heaters are the segment where safety features go missing. They are cheap, they are high-volume, and the two mechanisms that cost money — a tip-over cutoff and a child lock — are frequently the ones dropped. This unit publishes both, and that is the substantive reason it appears in the nursery and small rooms roundups.
The child lock in particular is uncommon at any price and rare at this one. It freezes the control panel, which matters because a tabletop heater's controls sit at exactly the height a standing toddler explores.
Top pick · A desk, a nursery, a small bedroom
The short answer to “which small heater has a child lock”: a tabletop unit that publishes a tip-over switch, a child lock and an auto-eco mode rather than leaving you to guess.

Who it is for
A small room — a nursery, a home office, a bedroom under about 150 sq ft — where the controls need to be lockable.
What it is not for
An open-plan living room. A tabletop unit oscillating across a desk is not going to move 1,500 W of heat around 400 sq ft.
| Wattage | Per hour | 1 h | 4 h | 8 h |
|---|---|---|---|---|
| 1,500 W | 27.5¢ | $0.28 | $1.10 | $2.20 |
Computed at 18.34¢/kWh — the U.S. residential average for June 2026 (EIA, Electric Power Monthly, Table 5.6.A, released August 26, 2026). Your rate is on your own bill; substitute it and the arithmetic still holds. Figures assume full output for the whole period.
The AutoECO mode is relevant to those figures. An eco mode cycles the element rather than running it continuously, which is the only mechanism by which any heater genuinely reduces consumption — there is no efficiency difference between elements, only differences in how much they run.
Two things, and both are worth knowing. No coverage figure — Lasko does not state a square footage, so use the sizing rule: 1,500 W is about 150 sq ft in an average room. No listing mark in the listing text — check the rating plate on the unit for a UL or ETL mark when it arrives. How to verify one.
We are noting the absence rather than assuming the answer. A well-known brand very probably lists its products; “very probably” is not a specification, and this site does not print one as though it were.
It is a tabletop unit, which means it needs a hard, clear surface with three feet of clearance — and most desks and nightstands do not have that. It is also 1,500 W, so in an open-plan living room it is doing the same job as any other 1,500 W heater but oscillating from a table rather than the floor, which distributes less well. Large-room picks are a better shape for that job.
Yes. The listing publishes a child lock alongside a tip-over switch, a digital thermostat, an AutoECO mode and wide oscillation, which is why it appears in our nursery roundup.
Lasko does not publish a coverage figure. At 1,500 W and the standard 10 W per square foot, that is about 150 sq ft in an average room and about 120 sq ft in a drafty one.
The Amazon listing text does not state a listing mark. Check the rating plate on the unit itself for a UL or ETL mark and a file number, and verify it in the laboratory's online directory.
It cycles the heater rather than running it continuously, holding a temperature instead of producing full output. Cycling is the only mechanism by which any electric heater reduces consumption, since all of them are about 100% efficient.
For rooms under 150 sq ft, where 1,500 W is oversized and the thermostat is what actually matters.
Child lock, tip-over cutoff and cool-touch — the three published features a nursery heater must have.
How a PTC element self-limits its temperature, and which rooms ceramic heaters actually suit.
Both marks mean the same standard was met. Here is how to check that a listing is real.
1,500 W, a published 300 sq ft claim that survives the arithmetic, and a thermostat with numbers.
150 sq ft needs about 1,500 W — one heater exactly, with no margin. Here is what that means.
