Gas ONE GS-3400P Camp Stove Review

Bottom Line

The Gas ONE GS-3400P camp stove is an excellent beginner’s stove that more advanced camp chefs will appreciate as well. It has easy-to-use features, packs down for travel, has amazing power, and can use either propane or butane. Our drawbacks to this stove are limited, and compromises are mostly made to ensure its lightness. 

As a single burner, this stove can limit the meals you might want to make on it. If you have a cookbook full of one-pot meals, this may not be a drawback for you. However, if you are the one to love bacon and pancakes with your eggs (and for them all to be hot at the same time), this stove may not be a great option. One thing we missed from this stove was a wind guard, but we know that this omission helps keep this stove light and easy to fit into its little case to transport. And boy, does this thing transport easily! 

We love that this stove is one of the most versatile of our favorite camp stoves, enhancing its already great value. It can be used with either propane or butane, giving first-time users a chance to try out both fuel types. This dual-fuel feature also allows this stove to work well in all temperatures (as butane doesn’t perform well below 31 degrees). There’s no reason to leave this one at home for your next adventure.

How We Tested

We put this stove through four tests to provide a comprehensive approach to our rating. First, we timed how long it takes this stove to boil one liter of water. Before and after this test, we weighed the propane canister we used to measure the fuel efficiency of this stove. We then cooked a pan full of bacon to test the evenness of the cook and a pot of rice to test how well it can maintain a low heat.

Power

This stove took 8 minutes and 29 seconds to boil one liter of water. To test how well this stove boils water, we put it head to head with the other 8 stoves in our round-up of favorites. We found that this stove performed in the middle against the others. 

To test, we set each stove in the same controlled environment. A pleasant, 64-degree, windless spot on a flat surface. We used the same pot for each test and filled it with room-temperature water. 

While certainly not the fastest, this was definitely not the slowest boiler on our list. It powers through in time to help you get to dinner quicker.

Efficiency

We found this stove to be relatively fuel efficient. In a controlled environment, it took only 0.6 oz of propane to boil one liter of water, placing it as our second most fuel-efficient camp stove on our list of the year’s best.

We tested this metric by boiling exactly one liter of water in a controlled environment with no wind and no freezing temperatures. We weighed the bottle of propane before and after the water boiled, ensuring to turn the stove off as soon as the boil started rolling. 

We also used propane to test this stove’s boil time. Expect the fuel efficiency to change if you use butane or in cook different conditions.

Cooking Ability

We tested the stove’s ability to cook by evaluating its ability to simmer (AKA maintain a consistent and low heat), its evenness of cooking, and additional features. The Gas ONE GS-3400P gave us mixed results. 

To test the stove’s simmering ability, we used our favorite packaged risotto mix (sorry to my Italian ancestors). The rice needed to be added to boiling water, and then simmered on low heat while covered for 18 minutes. 

We found that the stove extinguished sometime within the first few minutes of simmering. The stove was set up in mid-30-degree weather with little to no wind and we used propane fuel. Initially, we set the stove to low. We walked away from the stove as it was cooking and didn’t keep a steady eye on it, coming back to a major disappointment when our 18-minute timer went off. We reset the timer, and turned the heat up slightly –– a medium-low flame. We found that turning the flame up did help keep it burning consistently. After this second round of cooking, our rice was perfectly fluffy and delicious. 

To further prove our theory, when we cooked bacon and boiled water on this stove, we kept it at a high heat and had no problems with the flame extinguishing. 

The stove does have an adjustment knob with a temperature rating. We found there to be a shorter range of adjustment here than on other stoves. Still, the temperature settings it does have work fine for all of our cooking needs. 

Though we had to wait longer for our lunch, this stove won us back with its ability to cook evenly. We tested this by laying three strips of bacon out, covering the entirety of the pan. Not only did the bacon cook very quickly, but it cooked evenly from end to end and from the outer strips to the middle. We were especially pleased with this result because our table was uneven, and the grease was collected at one end of the pan. 

The only other downside to this stove is its lack of wind guard. Trading such a convenience for its lightness and packability (see next section) is a compromise you’ll have to consider.

Portability

The Gas ONE is a very portable stove. It is not only one of the lightest that we tested, but it also has a convenient carrying case and fits easily in a packed car. 

At 3.1 pounds, this stove is the second lightest of our favorite camp stoves. Once packed into its carrying case, it feels almost like there’s nothing inside. 

The case opens like a suitcase and locks next to the handle to keep it shut when traveling. Its slim design fits easily into even the tightest-packed cars. Its packed dimensions are 13.5″L x 11″W x 4.45″H. We love that the propane adapter stashes within the butane panel beside the stove. The only clunky thing about this stove is carrying the fuel that goes with it. 

When we tested this stove, we could easily grab it when it was packed in its case, even with an arm full of camp supplies, and that convenience just made us happy.

Ease of Use

The Gas ONE single-burner stove is incredibly user-friendly and versatile. It supports both propane and butane, making it compatible with the same fuel we use for our two-burner setup—double-checking this for consistency. The ability to use either fuel ensures flexibility in different situations. When using butane, be sure to engage the fuel lock for safety.

One of the standout features is its built-in self-ignition system, which is integrated into a single control knob. This makes operation intuitive and effortless. The temperature control is clearly marked with a scale, allowing for precise adjustments and easy visibility of the burner’s upper and lower limits. Ignition is quick and reliable—it consistently lit on the first click in our tests.

Should You Buy the Gas ONE GS-3400P Camp Stove?

We believe this stove is a no-brainer. Small criticisms are outweighed by the benefits this stove offers. It is a great option for someone’s first stove or an additional burner for smaller trips. It is easy to use, powerful, cooks evenly, and packs well. 

This stove is probably not best for those who camp in large groups and need more burners to cook larger, more complicated meals. It may make for a nice addition for this type of person, but would not be recommended as the primary stove. 

Those who regularly camp in very windy places may want to look at other options, as this stove lacks a wind guard.

Coleman Cascade 3-in-1 Camp Stove Review: This one also has the ability for a flat top grill, but also gives you a slatted grill, and a burner, making this a more versatile stove for those wanting to pull out all the camp cooking stops.  

Snow Peak Home & Camp butane stove Review: Another one-burner stove that is even lighter and packs down even smaller. This stove runs off butane, however, and may not be the best option for those who camp in weather below 31 degrees. 

Jetboil Genesis Basecamp System Review: This is a double-burner stove that packs down like a single-burner. This is the most portable double burner on our list of favorite stoves this year. It even includes a pot and pan within its packing system.
