"Induction cooktop Kmart" is one of the most searched terms in this category — for good reason. Kmart's portable induction cooktops are cheap, easy to find in-store across Australia, and cover the basics well. Here's when that's genuinely enough, and when it isn't.
The short answer
A department-store portable induction unit is genuinely fine as a second burner, an occasional-use unit or a way to try induction — it uses the same technology and boils water at a similar rate, because every plug-in unit is capped by the same 10A power point ceiling. Step up to a branded unit if it will be your main cooktop: what you are buying is finer low-end control, a quieter fan and a longer working life, not more power.
What a budget portable unit does well
- Single-zone cooking for under $50–$80
- Good enough for boiling, simmering, and basic frying — the bulk of everyday cooking
- Zero installation — plug into any power point and go
- Ideal as a spare burner, for students, or occasional/backup use
Where budget portable units fall short
- Lower maximum wattage — searing and wok-level heat can feel noticeably underpowered against gas or a dedicated wok burner
- Fewer, coarser temperature increments than premium models, making fine simmer control harder to dial in
- Shorter typical lifespan under daily heavy use, particularly the touch controls and internal fan
- More basic pan-detection and safety cut-off behaviour compared to branded units built to a higher spec
When to upgrade to a branded portable or built-in unit
If you cook daily, want precise temperature control for things like candy-making, sous-vide-style searing, or delicate sauces, or plan to use it as your primary cooktop rather than a backup, a branded portable option like Tefal or Breville — or a proper built-in cooktop — will noticeably outperform a budget single burner in day-to-day use, not just on a spec sheet.
Our take
A budget portable unit is a genuinely good buy for occasional or backup use, and there's no shame in starting there. For daily cooking, the jump to a branded model or a budget built-in cooktop pays for itself in reliability and control within a year or two of regular use — the cost difference is small relative to how much time you'll spend using the appliance.
Everything plug-in shares the same ceiling
This is the key to the whole comparison. An Australian power point is rated at 10 amps, which caps any plug-in appliance at roughly 2,400W, and manufacturers leave headroom — so most portable units, cheap or expensive, top out around 1,800–2,100W.
That means a $70 unit and a $220 unit have broadly similar maximum power. Neither will boil water dramatically faster than the other. Brand does not buy you speed at this end of the market, and any comparison that implies otherwise is measuring the wrong thing.
What the extra money actually buys
| Department-store unit | Branded unit | |
|---|---|---|
| Price | $50–$90 | $120–$250 |
| Max power | Similar — both capped by the 10A power point | |
| Power levels | Few, coarse steps | More, finer steps |
| Low-heat behaviour | Often cycles full power on/off | Modulates more smoothly |
| Fan noise | Louder, more intrusive | Generally quieter |
| Build & lifespan | Shorter under daily use | Longer |
| Controls | Basic, sometimes poorly placed | Better laid out, more presets |
| Service & parts | Replace rather than repair | Sometimes serviceable |
The cycling problem, explained
The most consistent complaint about very cheap induction units is not power — it is what happens at low settings. Rather than genuinely reducing output, budget controllers often hold a low average temperature by switching full power on and off in a cycle. You can hear it and, more importantly, you can taste the result: sauces that alternate between still and boiling, chocolate that seizes, rice that catches.
At high heat this is invisible, which is why budget units review well for boiling and searing and poorly for anything delicate. If most of your cooking is "get it hot", the cheap unit is fine. If you simmer, melt or hold temperatures, this is the specific thing you are paying to avoid.
When a cheap unit is the right answer
- As a second burner for Christmas, entertaining or batch cooking — capacity you need a few times a year.
- To test induction before committing to a built-in and its electrical work. For under $100 you learn whether you like how it cooks and whether your pans are magnetic.
- For occasional or seasonal use — a holiday house, a caravan annexe, an outdoor setup.
- In a share house where it may not survive long regardless of what it cost.
When to spend more
- It is your only cooktop. Daily use exposes every weakness — the noise, the coarse control, the shorter life — and replacing a cheap unit every couple of years erases the saving.
- You cook precisely. Sauces, chocolate, custards, anything held at a steady low temperature.
- The kitchen is small or open-plan. Fan noise you would ignore in a large kitchen becomes a daily irritation in a studio.
If it is your only cooktop long-term, also weigh a built-in seriously — see our portable vs built-in comparison, and our portable brand guide for how the brands differ.
Safety and your rights, whatever you pay
Plug a portable induction cooktop directly into a wall socket — not an extension lead, not a power board shared with other appliances. A sustained 2,000W load is not what light-duty leads are built for, and this applies equally to cheap and expensive units.
And regardless of price or printed warranty, Australian Consumer Law statutory guarantees apply: goods must be of acceptable quality and last a reasonable time given their price and description. A $70 cooktop that dies in three months is not "you get what you pay for" — it is a faulty product, and the retailer owes you a remedy. Keep the receipt.
Frequently asked questions
Does Kmart sell built-in induction cooktops?
Kmart's induction range is portable countertop units — for a built-in cooktop you'll be looking at the branded manufacturers covered in our brand ranking.
Is a $50 induction cooktop safe to use?
Products sold in Australia must meet relevant electrical safety standards regardless of price point — the difference between budget and premium is mostly in durability, control precision and features, not baseline electrical safety.
How long does a budget portable induction cooktop last?
With occasional use, several years is realistic; with daily heavy use, expect a shorter service life than a mid-range or premium unit built for sustained daily cooking.
Are cheap portable induction cooktops safe?
Units sold through established Australian retailers must meet local electrical safety requirements, so a department-store unit from a mainstream retailer is safe when used correctly. Plug it directly into a wall socket rather than an extension lead or shared power board, and give it clear airflow around the cooling vents.
Will a cheap induction cooktop boil water as fast as an expensive one?
Broadly, yes. Every plug-in unit is capped at roughly the same maximum power by the 10A power point, so boiling times are similar. The differences show up at low heat, in fan noise and in how long the unit lasts, not in how fast it gets hot.
How long does a budget portable induction cooktop last?
Under daily use as a primary cooktop, often a few years rather than a decade — the cooling fan runs hard and the units get moved and knocked. Under occasional use as a second burner they can last considerably longer. Factor periodic replacement into the cost if it is your only cooktop.
