NeoChef Smart Inverter Microwave: What Inverter Actually Does in a Microwave

Standard microwaves work in pulses — full power on, then off, then on again. Inverter microwaves run continuously at variable power. The difference shows up in defrosting, reheating leftovers, and cooking foods that hate being blasted.

"Inverter" is a familiar word in aircond and washing machine marketing. In a microwave, it is more recent and more misunderstood. Here is what it actually does, and why it matters for the food you cook.

How a standard microwave works

A standard microwave has one power level: full. When you select 50% power, it does not run at half strength — it cycles on at full for a few seconds, then off, then on again, alternating until the timer expires.

That is fine for boiling water. It is bad for almost everything else.

Reheating rice at 50% power on a standard microwave means the rice surface gets blasted with full microwave energy for 3 seconds, then sits cold for 3 seconds, then gets blasted again. The outside hardens. The middle stays cold. The whole bowl gets unevenly hot pockets.

Defrosting chicken at 30% power has the same problem in a worse way: the edges start cooking while the centre is still frozen.

What a Smart Inverter does

An inverter microwave varies the power continuously. When you select 50%, it actually runs at 50% — the microwave field is steady, lower-intensity, with no on-off cycling.

The food sees consistent gentle heat instead of pulse-blasts. Three practical results:

1. Defrosting works. A chicken thigh thaws evenly instead of having cooked edges and frozen centres. The texture survives.

2. Reheating leftovers tastes like leftovers, not microwave food. Curry stays smooth. Rice stays fluffy. Bread does not get rubbery in the middle.

3. Cooking actual recipes is possible. Steaming fish, melting chocolate, softening butter, proofing dough — all things that fail in a standard microwave because the power swings too hard. An inverter handles them.

Concrete examples

**Reheating sambal:** at 70% on inverter, the sambal heats through in 90 seconds without scorching the edges of the bowl. On a standard microwave at 70%, the bowl edge browns while the centre stays cool.

**Defrosting chicken (500g):** 8 minutes on inverter defrost. The meat is fully thawed with no cooked patches. Standard microwave at "defrost" produces grey cooked corners.

**Melting dark chocolate:** 2 minutes at 30% on inverter, stirring once. On a standard microwave, the chocolate seizes at any setting because the pulse-bursts overcook small areas.

What the 39L NeoChef adds

Beyond inverter cooking, the LG NeoChef 39L Smart Inverter Microwave Oven (Objet Collection) brings three things worth flagging:

**Capacity** — 39 litres fits a 36 cm dinner plate or a small roasting tray. Most Malaysian apartments have microwaves at 20–25L. Upgrading capacity changes what you can reheat in one go.

**Easy-clean interior** — anti-bacterial enamel that wipes clean instead of staining. After a week of curry reheating, the difference is obvious.

**Sensor cook** — the unit detects steam levels to auto-adjust cook time. Useful for vegetables and fish. Less useful for rice.

The Objet Collection finish is design-led — beige or matte body — so the unit fits visible kitchens instead of being relegated to a cabinet.

What it costs to run

A 1000W microwave on a 5-minute reheating cycle uses about 0.08 kWh — that is RM0.04 per use at TNB 2026 rates. Even at 4 uses per day, monthly electricity cost is around RM5. Inverter does not save meaningful electricity on a microwave — the savings show up in food quality, not your TNB bill.

When inverter is worth the price gap

A standard 25L microwave costs RM350–500. An inverter 39L NeoChef costs more. The price gap is justified if:

You cook actual meals at home and reheat leftovers daily

You defrost meat regularly and care about texture

Your kitchen has space for a 39L unit

The microwave is visible and the design matters

It is not worth it if:

The microwave is used twice a week for instant noodles and Milo

Space is tight and 25L is plenty

You do not do any real cooking through the microwave

For most homes that cook, the inverter advantage is real. Once you have used one, going back to a standard microwave is noticeable — and not in a good way.

Subscription fit

Microwaves are usually a buy-once category. The LG Subscribe model is more relevant for households that want a bundle (microwave + dishwasher + fridge, for example) where the subscription covers the whole kitchen at one monthly rate, with maintenance and replacement bundled if anything breaks during the term.

For a single microwave purchase, buying outright may still make sense. For a kitchen refresh, the bundle math changes.
