Iwatani 35FW Single-Burner Butane Portable Cooktop Indoor & Outdoor Cooking Stove Medium

I have wanted one of these butane powered cooktops for a while. I don't know about you, but sometimes I don't like messing up the big cooktop after I spent 20 minutes cleaning it. Sometimes I get a little wild with Italian cooking and my pan tossing skills don't always work out well. What I'm saying is, cooking can be messy and I wanted a non-induction portable cooktop that I could use on the kitchen island with a silicone mat, outdoors on a table, or if I needed to tailgate, I could take it with me. There are plenty of these available and if you watch any folks cooking on YouTube, you've probably noticed over the last couple of years that these have become much more prevalent than they used to be. I tend to avoid buying the bottom end of things but admittedly, this was more spendy than I was targeting. However, I liked the design, and I have never had a bad experience with a Japanese made cooking applicance or utensil in the kitchen, so I pulled the trigger. What you get for the money is a very solid cooktop that is well made, looks good, and most importantly, it delivers low to high heat. You should manage your expectations that using a super large pan on this burner is not recommended since the heat can transfer into the butane canister, but it does have an overheating safeguard built in that I hope I never need or approach. Turning the knob feels quality and it ignites perfectly, every single time. It allows for very good heat control, from flames rolling up the sides of a small skillet, to a very mild simmer. It includes a nice case to store the cooktop in when not in use. I typically cover mine with some foil when in use to make cleanup easier, but otherwise, it doesn't get much easier to use, and based on the fact my Iwatani torch is still going strong 10+ years later, I don't see this letting me down anytime soon. While it commands a higher price, I think the quality matches the price point in terms of what you can expect in 2025.

I assumed all of these portable butane burners were cheap Chinese products and were all the same. I was thoroughly embarrassed by my cheap burner during a picnic with friends when the meat I was cooking took 3x longer to cook and ended up a soggy mess with no sear. I had to transfer my meat to one of my friend’s burners to finish cooking after he had already finished 3 rounds of meat. I immediately searched butane burners when I got home and found this Iwatani burner, and was impressed that it was made in Japan. The difference in heat output is amazing, and blows my old burner away! It even boils water faster than a burner of similar size on my kitchen gas range. The build quality is very good, and the unit is light and easy to carry. It is expensive for a portable butane burner, but the price is well worth it to me for its excellent functionality and retribution for the embarrassment I suffered from my old burner. This burner finally earned me the respect I was desperately seeking from my friends, and you can’t put a price on that.

Excellent performance and quality out of this compact portable stove. A must for car camping and emergency home use. Very even flame and consistent temperature. Simple to use and transport. Japanese quality and engineering at its finest.

I've only used this stove a few times, and I like it a lot! This Iwatani stove is so much easier to use compared to my Coleman single burner stove. With this Iwatani stove, I simply open the lid, insert butane cannister, close the lid, press the dial to on position, and bam! Fire instantly comes on nice and hot! I can then lower the heat by turning the dial the other direction. When done cooking, I simply take the butane cannister and place the cap back on, then insert the cannister back into the compartment BACKWARDS for easy storage when not in use. I got this tip from other user comment (thanks by the way!). Contrast this with my Coleman single burner stove in terms of operation. With the Coleman stove, you need to first insert the pipe that screws into the stove (don't lose the pipe, by the way), then screw in the propane cannister into the pipe that screws into the stove, then need to get my long match/torch to light the darn stove while turning the dial to the on position. That's literally 4 separate items needed to make everything work (Stove, Pipe, Cannister, Match). The Iwatani stove is so much easier to use compared to my Coleman stove. I was able to boil a large kettle of water quickly and effortlessly. Because the Iwatani stove is well built, the unit didn't get too overly hot after using for only several minutes. A couple points further. As others have noted, the included plastic carry case is...well, cheap! The actual case is okay, but the 2 closing latches on top are poorly designed and constructed, and is a bit loose and wobbly when closed with the stove inside. When carrying the stove inside the carry case, you will need to make sure the latches don't come loose. Both of my Iwantani stoves have the same lousy carry case design. I also discovered that if you inadvertently open the carry case with the stove upside down, the top piece of the stove (the windbreaker part) will simply fall off, as it seems like there is nothing to hold it in place other than gravity when the stove is right side up. Lastly, DON'T buy the Iwatani brand of butane cannisters like I did. It's very expensive, and I doubt it's much better to justify the high cost. I ended up finding an Asian restaurant supply store nearby me that sold a 4 pack of butane cannisters for only $4.25, such a bargain! Better yet, they also had a small supply of this same Iwantani stove, so I bought a 2nd one directly from the same store! I now have 2 of these Iwatani stoves! I plan on using one to cook water, and the other one for cooking food or whatever. I don't know how these things will hold up over time, but I can say this stove looks well made and is worth the extra cost. I will be using this stove for camping. I highly recommend this product!

This is an excellent burner. I used it to boil pasta in a 16-quart pot this evening, and it came to a rapid boil. The water boiled faster than it does on my stove top! Given its quality, it was well worth the higher price. The Japanese never disappoint when it comes to well-made, well-constructed products. As a matter of fact, I came back to this product because it performed so well, I am purchasing another. ~~ Update: 11/11/2025 - FIVE MORE STARS! My son took this to an outing at San Diego Bay with his friend and their little children. His friend liked the burner so much that I've come back again to purchase another for my son's friend for Christmas. It will make for a lot of fun memories when they go out and grill hot dogs and hamburgers while fishing with the kiddos. They used my Lodge cast iron grill to cook with and it worked great. ALSO, and very importantly, it was windy and didn't affect the flame; it still worked great. I'm telling ya... spend a few extra bucks for a better product, you won't regret it.

Just received it today and used it to make my dogs food for the week. It really oozes quality compared to burners that are usually a third or quarter of the price of this unit. Really excellent flame control and I swear this thing can really output some high heat! Finish is excellent. Give it a try!

I've had this for a few days, using it every day for stir fry, steaming rice in a pressure cooker, and boiling water to make tea. Prior to this, I used a Gas One 15K BTU stove for about 2 years for the same end. So this is coming from someone with quite a bit experience with portable stoves. Compared with the Gas One stove, the Iwatani unit clearly needs the dual flame setup. The dual flame refers to flames coming from both the inner and outer circles of the burner head. This is caused by ports/orifices built in both the inner and the outer circles of the burner head. Gas One has that setup, whereas Iwatani does not. Don't know if dual flame is patented technology. Otherwise, Iwatani could easily implement it in the next iteration of this stove. With wok cooking, the dual flame is almost a must, as the bottom of the wok needs to be SUPER hot. Some have even gone the extra step of buying a focusing ring to, duh, focus, the fire to the bottom of the wok. But one reviewer cautioned about this; he said that he experienced damage to the metal and plastic in the top part of the stove. Additionally, as many have pointed out, the case is too flimsy and shoddy. At $90, it should have come with a better/sturdier case. Some of the testing tools I use for my car come with very strong molded plastic cases. Maybe Iwatani could pick up a page from there? The pros of the Iwatani unit vis-a-vis the Gas One unit are very obvious: thicker metal and better build. The whole thing just looks more polished than Gas One. Another thing I should point out is that the wok actually sits LEVEL on the Iwatani stove, whereas on the Gas One unit, it has never been able to for the two years I've used it! I had thought that this was due to the uneven surface I had sit the stove! This is not the case with the Iwatani unit, however. Even on a slightly sloped surface, the wok still sits level on the stove. In short, this is a very good stove. A little on the expensive side, but you get what you pay for. If Iwatani could implement dual flame in the stove's next iteration and include a sturdier case, this would absolutely be the best stove in the market.

Great stove for normal everyday small cooking jobs, camping trips or emergency preparation for power outages. Unit arrived in perfect condition in the excellent case, was shipped very quickly. It may be a little more than most, but the quality is super! Get it..you won't regret the decision!
