Gas One GS-3400P Dual Fuel Stove review

This assessment covers Gas One’s standalone US GS-3400P, SKU GS-3400P. It is a one-burner stove, not the similarly named GS-3400P-KIT, which adds a nonstick griddle. The review is based on model-specific pages and a model-specific instruction copy, not on owning, cooking with, timing, measuring or testing the stove.

Two fuel routes, but only one burner

Gas One describes the GS-3400P as an 8,000 BTU dual-fuel stove that takes an 8-ounce butane canister or a 16.4-ounce propane cylinder. The exact product page says fuel is not included and marks the stove for outdoor use only. The instruction copy reproduced under the GS-3400P model name identifies a Gas One GAS-1 non-refillable butane canister and shows a separate propane-cylinder setup. Those are alternate arrangements, not a promise that any cartridge, adapter, refillable bottle or bulk cylinder will connect. The current storefront page does not itemize every regulator or hose in the box, so check the exact package and the manual supplied with it before choosing the propane route.

There is one burner and one cooking position. The dial is described as adjustable, and Gas One claims control from high heat down to simmering. That makes the model a plausible fit for one-pan meals when an ordinary single burner suits the routine; it cannot boil a kettle while another pot cooks. The published output is a manufacturer claim rather than a timed boil or independent heat test. The available GS-3400P manual copy lists 8,367 BTU/h maximum, while the current product page says 8,000 BTU. Both figures remain visible as conflicting specifications rather than a basis for ranking this stove against another.

What the dimensions and weight can—and cannot—tell you

The product page lists a 13.5 by 11.2 by 4.4-inch footprint, a metal body with an enamel steel drip pan, piezo ignition and a ring-shaped windguard around the burner. The image shows the stove itself and does not establish its packed accessories. Although the page calls the windguard a way to protect the flame, no inspected source for this exact item approves adding a separate windscreen. Treat that permission as unknown; a built-in ring is not a license to wrap or shield an open-flame appliance.

The same page lists 3.3 pounds, its storefront variant data says 2,613 grams, and the model-specific instruction copy says 3.33 pounds. The sources do not give a consistent measurement basis, and none labels a manufacturer minimum stove weight. This review therefore does not treat any one number as a bare-stove carry weight or use it to pass a strict weight cap. The product and manual sources also do not establish a maximum pot diameter or cookware load. Check the exact manual and choose cookware that sits securely within its supports; a product image is not a fit or stability test.

Safety details belong to the exact unit and connection

Gas One marks the product for outdoor use only. The model-specific manual copy also warns against operation below 32°F, but the current storefront page does not link that revision; confirm the instructions supplied with the exact stove. In particular, do not treat an alternate fuel as permission to ignore the unit’s temperature limit. Use the stove outside in open air, never in a tent, vehicle, camper or home, and follow the manufacturer’s setup, leak-check, clearance and shutdown instructions. The page’s descriptions of cartridge ejection and automatic shutoff are design claims, not independent evidence that the stove is safe in a poorly ventilated location or with an incompatible fuel connection.

A separate CPSC notice, recall 21-197, covers specific Gas One propane adapter hoses identified as models 50140, 50140-08, 50140-012 and 50140-05GA from Pearl River 3Q20 and 4Q20 batches. That notice does not identify the GS-3400P stove itself, and the manufacturer page does not identify the model or batch of every hose a seller might supply. If using a separate Gas One propane hose, check its stamped model and batch against the notice rather than assuming that all adapter hoses are the same item.

When the standalone version makes sense

The GS-3400P is most relevant for a drive-up site, tailgate or outdoor backup plan where one adjustable burner and the choice between a compact butane canister and a small propane cylinder are worth carrying. Its appeal is the alternate fuel arrangements, piezo ignition and simple one-pan layout, not a verified cooking-speed advantage or a measured wind-performance claim. The option is useful only when the correct fuel and compatible connection are available, and the manual’s limits suit the trip.

Compare it with the GS-3400P-KIT only if the included griddle is useful: both packages describe the same GS-3400P burner, while the kit adds a flat-top surface intended for use instead of standard cookware. The kit does not add a second burner. If simultaneous pots, a confirmed large-pan limit, an approved separate windscreen or a dependable minimum carry-weight figure is essential, the current evidence does not establish those requirements for this stove. Choose another documented arrangement or obtain the exact manual and package specifications before buying.

Check the SKU and supplied equipment

Before treating a listing as the GS-3400P, confirm that the product title and stove marking say GS-3400P—not GS-3400P-KIT, GS-3600P or another similar Gas One model. Confirm which fuel connection is supplied, whether any regulator or hose is actually included, that fuel is separate, and that the manual covers the unit in the package. The manual copy and current page disagree on the maximum output, while page and variant weight fields also conflict. Those uncertainties affect numeric fit; they are not reasons to invent a value or assume a different model’s limits apply.
