Duxtop 9620LS (BT-350DZ) Portable Double Induction Cooktop, 1800W

Overview: who is this for?

The Duxtop 9620LS is a two-zone portable induction cooktop that plugs into a standard 120 V outlet. Duxtop's newer model number for it is BT-350DZ, and both numbers appear in the manual and on the Amazon listing. It is for van and camper kitchens that already have the electrical system to run an 1,800 W appliance and want to cook two things at once without a second unit and a second outlet.

What the Amazon link sells: the listing this page links to is titled "Duxtop LCD Portable Double Induction Cooktop 1800W Countertop Burner 9620LS", with the model given as BT-350DZ and part number 9620LS. That's the unit described here: two induction zones in one housing, sharing one 1,800 W supply.

Operating location: induction burns no fuel, so it produces no carbon monoxide or other combustion gases and isn't labelled outdoor-only. Cooking still makes steam, grease and smell, so a roof fan or open window matters for general cooking ventilation. Duxtop's manual also says the unit is for household use, should sit on a dry, stable, non-metallic surface, and shouldn't be used in a wet outdoor environment.

Choose this if:

• You regularly cook two pans at once, for example rice and a stir-fry, or pasta and sauce, and want both on induction.
• Your inverter can already supply about 2,000 W continuous and your battery can deliver around 170 A at 12 V.
• You have about 24 inches of counter width for it, plus clearance, at least while cooking.

Skip this if:

• Your inverter is under about 2,000 W continuous. Both zones together still draw up to 1,800 W, the same peak as a single-zone unit.
• Counter space is tight. The single-zone Duxtop 9100MC is roughly half the footprint.
• You mostly cook one-pot meals. Then the second zone is weight and bulk you carry for nothing.

This is a research-based review. VanLifeKitchens doesn't test products hands-on. The specifications come from Duxtop's user manual for the 9620LS / BT-350DZ and from the Amazon listing we link to. Power and battery figures are our estimates from the rated draw, and the assumptions are stated where they're used.

Specifications and sources

Two things in that table matter more than the rest. The zones aren't equal: the left zone reaches 1,800 W and the right only 1,000 W. And the unit never draws more than 1,800 W in total, however you set the two zones.

How the power sharing works

Duxtop's manual explains this plainly. Used alone, the left zone can run at up to 1,800 W and the right at up to 1,000 W. With both running, their combined power is capped at 1,800 W. If you raise one zone, the other turns itself down if it needs to. Duxtop's own example: with the left zone set to 1,000 W, the right zone runs at no more than 800 W.

The manual's power-sharing table shows how this plays out at the top settings. Push the left zone to its highest levels and the right zone drops to zero. At the left zone's level 8.0 (1,400 W), the right zone can still run at its lower settings. In practice that suits how most people cook: one pan hard (searing, boiling) on the left, one pan gentle (simmering, keeping warm) on the right.

What it doesn't do is give you two full-power burners. Two big pots boiling at once will each get less power than a single 1,800 W unit gives one pot, so batch boiling isn't faster. The advantage is running a simmer next to a sear, not doubling your output.

Low settings and cycling

Duxtop's manual says Power Mode settings from 0.5 to 4.5 use power cycling: the element switches on and off, and the wattage shown for those levels (100 to 740 W on the left) is an average. Above level 5.0 the element runs continuously. That matters for gentle cooking. Cycling at low settings is normal for portable induction, but very delicate jobs such as melting chocolate or holding a thin sauce just below a simmer can still catch on the pulses. Stirring and a heavier pan smooth it out.

Temperature Mode holds a target from 100 to 460°F. Duxtop's manual is candid that the sensor sits under the glass, so the reading is an estimate of the pan's temperature and will vary with the cookware. It recommends Temperature Mode for frying and browning, and Power Mode for boiling.

Power: what it takes to run this in a van

All of the figures below are our estimates from Duxtop's rated draw. We didn't measure them. They assume an inverter running at 85–90% efficiency, a 12 V nominal battery, and a pure sine wave inverter, which is the general recommendation for induction cooktops. Duxtop's manual itself asks for a dedicated 120 V, 15 A outlet that no other appliance shares.

Inverter and battery current

At the full 1,800 W, an inverter draws roughly 2,000–2,120 W from the battery, about 167–176 A at 12 V. The inverter's continuous rating, not its surge rating, needs to be above that with some margin, so plan on about 2,000 W continuous as a minimum and more for comfort. Your battery's BMS needs to deliver that current continuously, and the cables and fuse between battery and inverter have to be sized for the inverter's rating.

That is identical to the single-zone Duxtop 9100MC, because both are capped at 1,800 W. Buying the two-zone unit doesn't make your electrical system's job harder at peak. It does make it more likely that you run near peak for longer, since two pans are cooking at once.

An inverter of this size is a serious DC installation. Follow the inverter maker's installation instructions, and use a qualified RV electrical technician where codes or your insurer require one. Our guide to running an induction cooktop from a power station covers which portable stations can run 1,800 W, such as the EcoFlow DELTA 3 and the Anker SOLIX C1000.

Battery energy per meal

Assumptions: the DC column adds inverter losses at about 88% efficiency, and the averages assume one zone running hard and the other at a simmer, which is how the power sharing is designed to be used. Lids on pots and turning the hard zone down once things boil reduce these numbers considerably.

For a couple cooking two meals a day this way, 60–100 Ah a day on cooking alone is plausible, before the fridge, lights and devices. That usually points to 200 Ah or more of lithium with solar and alternator charging. Model your own setup in the power calculator, and see the van kitchen power budget guide for the full daily picture.

Size, weight and fit

The manual lists 23.9 x 14.2 x 2.4 inches and 12 lb 7.7 oz. That's about twice the footprint of the 9100MC and roughly double its weight. In a van galley, that much counter is often the whole working surface. Many owners of two-zone units store them and bring them out to cook, rather than leaving them on the counter.

Duxtop asks for at least 4 inches of space around the whole unit for ventilation and says not to block the rear and sides. The cooling fan draws air in and pushes it out through the housing, so a recessed cutout in a tight cabinet is a poor idea. Treat the operating footprint as about 32 x 22 inches including clearance. The manual also says not to place objects heavier than 25 pounds on the surface, which rules out very large, full stockpots and cast-iron Dutch ovens filled to the top.

For travel, pack it flat with something soft over the glass and secure it so it can't slide. Ceramic glass tops scratch when cast iron is dragged across them and can crack if something heavy lands on them.

Cookware

Induction only heats cookware with a magnetic base. Duxtop's rule of thumb: if a magnet sticks to the bottom, it will work. Its manual lists cast iron, iron, magnetic steel, enamelled iron and stainless steel with a magnetic base as suitable, and glass, ceramic, copper, aluminium and non-magnetic 18/10 or 18/8 stainless as unsuitable. Bases need to be flat and at least 5 inches across.

For a two-zone setup in a van, two pans that nest are the practical answer. The Magma Nesting 10-piece set is sold in an induction-ready version, and our nesting cookware for induction guide goes through what nests inside what. A cast-iron skillet such as the Lodge 10.25 inch is a good fit for the left zone's higher output. Avoid large pans on the right zone, which tops out at 1,000 W.

How it fits a van kitchen

The 9620LS makes most sense in a van with a large electrical system, a fixed galley and two people cooking proper meals. It replaces a two-burner propane stove without combustion gases inside, and it's the closest portable induction gets to a home cooktop.

It makes less sense in a small van, a solo build or anywhere the inverter is undersized. For those, a single-zone unit does nearly everything a two-zone unit does, because the total power is the same. A single-zone 1,800 W cooktop plus a second pan kept warm off the heat covers a lot of two-pan meals.

A fuel stove used outdoors is a common backup for induction vans in winter, when short days mean little solar. If you add one, cook with it outside the van according to its manual. See the induction vs butane vs propane guide for how the options compare and the van cooking safety guide for the location rules.

Limitations

• Unequal zones. The right zone tops out at 1,000 W. It suits simmering, not searing.
• Shared 1,800 W. Two zones never add up to more power than one 1,800 W unit.
• Bulk. At nearly 24 inches wide and over 12 pounds, it's a lot to stow.
• Household appliance. Duxtop's manual says household use only and not in a wet outdoor environment, so it isn't a rain-proof camp cooktop.
• Low-setting cycling. Settings below 5.0 pulse rather than run continuously.

Verdict

The Duxtop 9620LS is a sensible way to get two induction zones from one standard 120 V outlet, with a clear power-sharing system and a two-year warranty. Its real benefit is cooking a fast pan and a slow pan at the same time. It doesn't give you more power than a single-zone 1,800 W cooktop, so it won't help an undersized electrical system. If your van can already run the Duxtop 9100MC and you have the counter space, it's a worthwhile upgrade. If not, start with the single-zone unit. Our head-to-head comparison goes through the trade-offs, and the cooktops buying guide covers every option on the site.

FAQ

Can the Duxtop 9620LS run both burners at full power?

No. Duxtop's manual caps the combined output at 1,800 W. Used alone, the left zone reaches 1,800 W and the right zone 1,000 W. With both running, raising one zone makes the other turn itself down if needed.

What inverter does the Duxtop 9620LS need?

By our estimate, at least about 2,000 W continuous, pure sine wave. At 1,800 W the inverter draws roughly 167–176 A from a 12 V battery. That's the same peak as the single-zone Duxtop 9100MC. Duxtop's manual asks for a dedicated 120 V, 15 A outlet.

Is the Duxtop 9620LS safe to use inside a van?

It burns no fuel, so it produces no carbon monoxide and isn't labelled outdoor-only. You still need general cooking ventilation for steam and grease, the 4 inches of clearance Duxtop asks for around the unit, and an electrical system installed to the inverter maker's instructions.

How big is the Duxtop 9620LS?

Duxtop's manual lists 23.9 x 14.2 x 2.4 inches and 12 lb 7.7 oz. With the 4 inches of clearance it asks for, plan on roughly 32 x 22 inches while it's running.

What warranty does the Duxtop 9620LS have?

Duxtop's manual gives a two-year limited warranty from the date of purchase, for the original purchaser, covering defects in material and workmanship under normal household use.

What pans work on the Duxtop 9620LS?

Flat-bottomed pans with a magnetic base at least 5 inches across: cast iron, enamelled iron, carbon steel or magnetic stainless. Aluminium, copper, glass, ceramic and non-magnetic stainless won't heat.
