Your needs, this model
Does it fit your priorities?
Does the GS-4000P support boiling and adjustable cooking?
Gas One's exact page claims 12,000 BTU and describes adjustable heat for boiling and simmering. That is a manufacturer capability claim, not an independent boil time or a low-flame stability test; the one-burner layout still allows only one pan position at a time.
Explore this need in the finder →Which fuel packages and connections should I confirm?
The page lists an 8 oz butane canister or a 16.4 oz propane tank and says fuel is not included. It does not itemize the propane adapter/regulator or say that a carry case is in the current package. Confirm the exact supplied hardware and manual rather than assuming a threaded backpacking canister connection.
Explore this need in the finder →Can it meet a strict carry-weight, pan-size or separate-screen rule?
Not from the reviewed record. The product page says 4.22 lb while the unlabelled store variant metadata says 3,039 g; neither is a manufacturer minimum-stove figure. The page also gives no maximum pan diameter and no approval for a separate windscreen.
Explore this need in the finder →The Gas One GS-4000P is a single-burner dual-fuel camp stove built in a visibly raised frame. Gas One's current US page claims 12,000 BTU, lists an 8-ounce butane canister or 16.4-ounce propane tank, and describes adjustable heat for boiling and simmering. The product photo shows one burner assembly. This is a tabletop cooking layout, not a two-position stove, and the page's cooking claims remain manufacturer claims rather than independent measurements.
Raised layout and fuel choices
The GS-4000P's raised body is its most visible distinction from the flatter GS-3100P. Gas One says the elevation is intended to improve airflow and cooking comfort, but the page does not supply a comparative test or establish how much clearance the user should leave. Its listed body dimensions are 13 by 11.5 by 3.6 inches. Those dimensions describe the stove, not the full footprint needed for a fuel cylinder, cookware handles, nearby combustibles or airflow. Use the exact manual and a stable outdoor surface; do not infer a minimum safe table size from a product rendering. The manufacturer lists two alternate fuel containers: an 8-ounce butane canister and a 16.4-ounce propane tank. Fuel is not included. The exact page does not itemize a regulator, adapter hose or carrying case in its current package copy, so check the exact box contents if propane or a storage case is part of the plan. The listed butane/propane arrangements should not be confused with a threaded MSR or Jetboil backpacking canister. A fuel-size statement is not proof that an arbitrary canister or adapter will fit.Cooking intent and what is not documented
Gas One describes adjustable heat for boiling and simmering, and publishes a 12,000 BTU rating. That supports a feature-level match for someone who wants a single burner capable of changing heat, but it does not establish a measured boil time or stable low flame. One burner means one pan at a time; choose another layout if two pots must cook concurrently. The current page does not publish a maximum cookware diameter, cookware load, or a permission to add a separate windscreen. A separate screen is a safety question for the manual, not an accessory decision to make from the raised frame or a photograph. There are safety features listed for the butane route: a cartridge ejection system, automatic shutoff and a safety lever. These are manufacturer statements, not independent tests and not a substitute for checking the exact instructions. The product page identifies the stove for outdoor use and says fuel is excluded. Do not use a fuel-burning camp stove inside a tent, vehicle or home. Any propane adapter should be identified and checked by its own model and production markings; a hose recall naming particular hose batches should not be expanded into an unqualified claim about the stove itself.Weigh the published figure carefully
Gas One lists the product at 4.22 pounds. Its Shopify variant record separately carries 3,039 grams, or about 6.7 pounds, without explaining whether that is product, packaging or fulfillment mass. Neither figure is labeled as the manufacturer's minimum bare-stove weight, so this review does not use either to satisfy a hard packing cap. The distinction is consequential: the GS-3900PB page lists 6 pounds but its variant metadata also disagrees, while the GS-3100P page exposes a variant mass with no bare-stove basis and does not publish a regular product-weight figure. None should be ranked as a verified min-weight comparison. The product page says the GS-4000P is aluminum and puts the 12,000 BTU claim alongside adjustable flame control. Its stated 13 by 11.5 by 3.6 inch dimensions and one-burner layout are useful for initial planning; pan clearance, case contents, adapter contents and exact travel mass still need a package-specific check. If those unknowns are hard requirements, keep the model in the research list rather than treating an attractive photo or a nominal output number as proof of fit. Compared with the GS-3100P, the GS-4000P page makes the flame-adjustment and simmer claim more explicit and features an elevated frame, while the GS-3100P page specifically describes a ring windguard and carrying case. The GS-3900PB has a higher published output and an exact manual with more detailed fuel setup, but a different weight conflict and package questions. All remain one-burner stoves. No hands-on use, flame test, boil test, scale measurement or comparison trial is claimed for this review.Key specifications
