Duxtop 9620LS Double Induction vs Duxtop 9100MC Induction Cooktop

The short answer

For most van kitchens, the single-zone Duxtop 9100MC is the better buy. Both cooktops are capped at 1,800 W, so both need the same inverter and battery. The 9100MC does it in about half the counter space, at about half the weight, with push buttons that cope with wet fingers, and it costs considerably less.

Buy the two-zone Duxtop 9620LS if you regularly cook two pans at once and have the counter for it. Its power sharing lets one pan sear on the left zone while the other simmers on the right, inside the same 1,800 W budget. It doesn't make anything boil faster, and it doesn't ask less of your electrical system.

Both are induction, so both cook without combustion gases. Neither is labelled outdoor-only, and both still need general cooking ventilation for steam and grease. Full details are in our Duxtop 9100MC review and Duxtop 9620LS review. For every cooktop type side by side, see the cooktops buying guide.

Quick comparison

Sources: Duxtop's 9620LS / BT-350DZ manual for the 9620LS, and the Amazon listing and Duxtop manual for the 9100MC, as cited in our reviews.

Power: identical at the top

This is the point most buyers miss. The 9620LS's two zones share one 1,800 W supply. Duxtop's manual says the left zone reaches 1,800 W on its own and the right zone 1,000 W, and with both running, their combined output never exceeds 1,800 W. Raise one zone and the other turns itself down if needed.

So at peak, the two cooktops draw the same: by our estimate, about 2,000–2,120 W from the battery through an 85–90% efficient inverter, or roughly 167–176 A at 12 V. Both need an inverter of about 2,000 W continuous or more, a battery and BMS that can deliver that current, and cables and fusing sized for the inverter. Duxtop asks for a dedicated 120 V, 15 A outlet for both.

Where they differ is how long you run near peak. With two pans going, the 9620LS is more likely to sit close to 1,800 W for most of a meal. Our rough estimate for a two-pan dinner, about 25 minutes at an average of 1,100 W combined, is around 43 Ah from a 12 V battery, against about 24 Ah for a single pan for 20 minutes at 750 W. Those are estimates with stated assumptions, not measurements. Model your system in the power calculator, and see whether a power station can do the job in our induction and power station guide.

Edge: tie on peak demand. The 9100MC is easier on daily energy simply because it cooks one pan at a time.

Cooking two things at once

This is the 9620LS's reason to exist. Rice on one side and a stir-fry on the other, pasta and sauce, eggs and a kettle for coffee: the two-zone unit lets you do these together, with each zone set independently in Power Mode or Temperature Mode.

The catch is the uneven zones. The right zone tops out at 1,000 W and has 10 settings, while the left has 1,800 W and 20 settings. Duxtop's power-sharing table shows the right zone dropping to zero when the left runs at its highest settings. So it's one strong zone and one gentle one, which suits how most two-pan meals work but isn't two full burners.

With the 9100MC, two-pan meals mean cooking in sequence: rice first, rested under a lid and a towel, then the stir-fry. For a lot of van cooking, that works fine.

Edge: Duxtop 9620LS, clearly, if you cook two pans together.

Size, weight and storage

Counter space in a van is usually the scarcest resource in the kitchen. The 9620LS's 23.9 x 14.2-inch top is roughly double the 9100MC's 11.4 x 14. Add Duxtop's 4 inches of clearance around each unit and the 9620LS needs roughly 32 x 22 inches while running, against about 19 x 22 for the 9100MC.

Weight follows: 12 lb 7.7 oz against about 6.2 lb. In storage, the 9100MC fits in a drawer or cabinet that the 9620LS won't.

Edge: Duxtop 9100MC.

Controls in a moving kitchen

The 9100MC has a panel of physical push buttons. The 9620LS uses a touch panel with LCD displays for each zone and a child lock per zone. Touch panels can misread through wet or greasy fingers or water on the glass, which happens in small kitchens. Physical buttons register anyway. That's a usability difference, not a reliability claim.

The 9620LS does have conveniences the 9100MC lacks: a Boil button that jumps to full power with a 10-minute timer, a Keep Warm button at 140°F, and independent timers for each zone.

Edge: Duxtop 9100MC for van practicality; 9620LS for features.

Low-heat cooking

Both cycle at low settings. Duxtop's 9620LS manual says Power Mode levels 0.5 to 4.5 switch on and off, with the listed wattage as an average, and run continuously from level 5.0. The 9100MC also cycles at low power, which owners say is short enough to hold a simmer with stirring. Neither is a precision tool for delicate sauces. For that, the NuWave PIC Gold offers temperature control in finer steps; see the Duxtop 9100MC vs NuWave PIC Gold comparison.

Edge: tie.

Value

The 9100MC is a budget cooktop. The 9620LS costs considerably more. Check current prices with the buttons on each review page.

What the extra buys is the ability to cook two pans at once from one outlet, with the power sharing handled for you. It doesn't buy any extra power. Both carry the same two-year Duxtop warranty in their manuals.

For most builds, the better use of the difference is the electrical system both cooktops need: battery capacity, an adequate inverter, or solar. If you already have that and cook two-pan meals daily, the 9620LS is worth it.

Which one should you buy?

Buy the Duxtop 9100MC if:

• You cook mostly one-pot or one-pan meals.
• Counter and storage space are tight.
• You want physical buttons.
• You'd rather put the money into battery and inverter capacity.

Buy the Duxtop 9620LS if:

• You regularly cook two pans at once and want both on induction.
• Your galley has about 24 inches of counter to give it while cooking.
• Your electrical system already handles 1,800 W comfortably.

FAQ

Does the Duxtop 9620LS need a bigger inverter than the 9100MC?

No. Duxtop's manual caps the 9620LS's two zones at 1,800 W combined, the same maximum as the 9100MC. Both need about 2,000 W continuous of inverter capacity by our estimate, and a dedicated 120 V, 15 A outlet per Duxtop.

Is the two-zone Duxtop faster than the single-zone one?

For one pot, no; both deliver up to 1,800 W to the main zone. For two pots, it's faster overall because they cook at the same time, but each pot gets part of the shared 1,800 W.

How much bigger is the Duxtop 9620LS?

Duxtop's manual lists it at 23.9 x 14.2 x 2.4 inches and 12 lb 7.7 oz. The 9100MC is about 11.4 x 14 x 2.5 inches and 6.2 lb.

Can both Duxtops be used inside a van?

Both are induction, so neither burns fuel or produces carbon monoxide, and neither is labelled outdoor-only. Both need about 4 inches of clearance for their cooling fans, general cooking ventilation for steam and grease, and an electrical system installed to the inverter maker's instructions.

Which Duxtop is easier to use in a van?

The 9100MC, for most people. Its push buttons work with wet fingers, it takes half the space, and it weighs half as much. The 9620LS adds a second zone, a Boil button, Keep Warm and per-zone timers.
