The Ohuhu stove

I bought one of these out of curiosity last week after seeing about a hundred reviews of the Ohuhu or it's clones on YouTube. I certainly don't need another stove and don't intend to cook on it but a lot of people do. At $16.99 it was worth a giggle if nothing else but I have fun with it and plan to keep it in the Casa since it is so tiny. At about 5.3'' in diameter and only about 4'' high collapsed it fits most anywhere but what is it good for? Well, for one thing it puts out an enormous amount of heat for it's size and the flame makes for a nice ambiance. Many people backpack and cook with it but I will be using it mostly on a picnic table on cool evening camping trips. Known as a stick stove as a result of the small twigs and wood chips it burns, mine will be used primarily with wood pellets which are cheap and easy to carry in the truck.

It's claim to fame is that it gasifies and the resulting combustion doesn't give off any smoke. It accomplishes this with a double wall construction with bottom vents and peripheral vents at the top that burn off the smoke. Whatever the magic, it just works! It would be fun for kids to roast marshmallows on, could be used to boil water, cook or fry and mine came with a grill that could be used to make toast or heat a cinnamon roll once the flame dies down. My test shows about an hours worth of burn time from a single load of fuel. Not a necessity but as a devout gadgeteer something I will enjoy playing around with.

But now it is getting hot and I needed to think about keeping cool in the Casa on summer camping trips, especially at night. I discovered a small and surprisingly versatile cooler on line that is basically a little swamp cooler or evaporative cooler. Having lived in the Mojave Desert for years I am quite familiar with swamp coolers and like them in a really dry climate. There are a number of these on the market and most are just junk that deliver far less than they promise. The one I bought seems to be a cut above and is a clever design. It can function as a 3 speed fan alone or as a 2 level evaporative cooler with all 3 speeds. In addition it has a built in night light that can be used as needed or kept off. A remote is provided that seems to work well and provides a redundant backup to the controls on the unit itself. A timer can be set at 1, 3, or 6 hours. Water capacity is almost 2 quarts, enough for at least 6 hours of cooling. It is USB-C powered and uses but 4 watts when on high cool. But as Professor Hobo would ask: "Is it any good?" It is my job to find out but I bought it to use inside the Casa on warm nights-a relatively small volume of area due to all the cabinets and storage areas inside. It definitely cools the air and does it very quietly providing some white noise to sleep with. I have some fancy fans in the Casa including an O2COOL model that I modified to run on 12v instead of the batteries it came with but those fans, although they help a lot, still just move ambient air around. This new unit has some actual cooling power. And it doesn't even have a name! It just says: "Multi Functional Air Cooler" on the box. With temps in the 90's next week I will be able to test it out and see if it delivers or not. Right now I get the impression that it is better than expected and at 4 watts will run damned near forever on an 1800 watt power supply.
 
Thanks Ive. I really enjoy your gear reviews. Do you have a link for the evaporative cooler you're using?
 
No link yet but I think I can find one. Bear in mind that I haven't field tested it yet but am impressed by the concept. I hope to spend a few days in Montana this month and give it a real workout.

Some of the new products I find are really amazing and represent some clear and forward thinking. The Anlook spotlight I bought is an example, it has a 10000 mAh battery that can charge other devices and is incredibly bright and last for hours instead of minutes. I used it to power the new evaporative cooler for 3 hours and the battery was only down 1 bar. It came with a belt hook, an adjustable stand and a tripod socket, newer models are even more capable. A far cry from the old tungsten bulb and 2 "D" batteries we used for decades.
 
More on the Ohuhu stove. I am doing some tests on it to determine if I am going to keep it and use it or give it away. Today I tried burning pellets in it instead of twigs and am impressed with the results. I started the stove at 3:55 today but had some issues getting the pellets to light. Pellets are made to ignite on the bottom but the Ohuhu type stoves require that the fire burns from the top down. Finally at 4:10 I got good flame and was in business. I used a few scraps of birch bark and the fire took right off but I am not fond of the black smoke the birch produces. I'll stick to clean burning fire starters in the future.

The fire burned with a perfect flame for 50 minutes on 3 cups of pellets, about 15 ounces and put out a lot of heat. After the flame burned down the pellets continued to glow so I put a little USB fan aimed at the base and by now-6:20-the embers are still glowing, the fan is moving hot air and the top of the stove is too hot to hold my hand over for more than a few seconds. At any point I could have added more pellets to continue the fire but I'll save that until fall. A 40# bag of pellets for $6.00 is going to make about 40 fires, keep the coffee hot, provide some heat and ambiance for a total outlay of about $23. I'm keepin' this thing, it's fun!

6:36 now and pellet embers still glowing and putting out a little heat....

Ive, if you want a faster start with pellets, consider adding this to one of your butane canisters. You will have your fire near instantly. Besides, everybody needs a blowtorch, right?

That's a good idea! I bought 2 cases of butane canisters when all of the tariff bullshit started up so I have about a 2 years supply by now. I cook with butane every day on an Iwatani stove so the torch would be a good compliment to the kitchen hardware.

Edit: I found a similar torch made by Iwatani that cost $35 but has a much higher rating and satisfaction quotient. Their products are top drawer and for anything using flame I am happy to spend a bit more. It will dovetail nicely with my sous vide cooker, not to mention that it will light pellets in a hurry!
 
Thanks Ive! It’s sort of a much cheaper version of the table top Solo stove. I ordered one out of curiosity like you.
This interests me for car camping because I have had a Solo (Lite) backpacking stove since the early 20-teens.
At the time it was a $35 larger, heavier (Korean?) knockoff of the original handmade, ~$80, (now $110) Bushbuddy gasifyer stove.
I came up with a small stainless grill to do steaks. Its main disadvantages are weight, bulk, and an appetite for twigs and small branch pieces making it harder to multitask in camp. Sooty residue was-is a lesser irritant. (edited) Also it cannot be used during Stage 2, and possibly even Stage 1 burn bans in some jurisdictions. Advantages include the Solo and other gasifyer stoves retain all of the embers and ashes within the stove so are safer than most "twig stoves" that have fuel feed holes in the sides and/or open bottoms that might have a separate ash pan.

But I found out from the ONP Ranger patrolling Seven Lakes Basin that I couldn't use forest floor litter in the Park for fuel.
It also worked quite well as a (heavy, bulky) windshield for a Trangia and even a featherweight "popcan" alcohol stove to have the option for wood or (Everclear) alcohol as a fuel source, (edit) but still not a controllable stove using propane - butane.
The alcohol option also didn't require closely watching & feeding the stove while preparing a meal allowing more opportunity to do other camp tasks or just relax a little after a hike.

At first glance the Ohuhu looks like it's lighter but might be harder to feed.

I see where pellets would be a nice option for car camp use 🤔.

Not sure it is legal when fires are banned. On the Deschutes, the BLM restrictions is no open flame. Only propane camp stoves and grills are allowed. Ran into the same thing in the Wallowa Whitman National Forest.

I can't use my Biolite stove (or before that, my Sierra zip stove) when there's a burn ban. I do like the little burn chamber stoves, though!

It has been several years since I used it so Thanks for the heads up! I've edited my post above. Plus there can be some jurisdictional differences so I would have to check each jurisdiction where I plan to use it before a trip.

Some of you have known about gasifying stoves for years and have probably used a Solo all that time but I have only been aware of them for about 3 weeks and have owned one for about 2 weeks now. I have learned a lot in 2 weeks having read at least 50 tests or reviews of various models and can state without contradiction that many of those tests/reviews are pure bullshit! The stove couldn't be simpler and can be made in a garage out of three tin cans and a cordless drill. But they are so inexpensive and are made out of so much better material than tin cans, my 5.5" model cost about as much as a hamburger and fries at your local pub.

Many of the reviews are very informative and accurate but the bad ones are awful. Some have a hard time assembling such a simple mechanism and install the fire ring upside down which should be counter intuitive to almost anyone. Almost...

Using pellets and trying to burn them from the bottom up is another big mistake but some try it anyway then complain that the stove is hard to start and doesn't burn well. Another pellet mistake-and not so obvious is try to add pellets while the flame is dying down. This can be done if careful but adding too many at once will quickly snuff out the flame resulting in smoke but little fire.

One of the biggest mistakes made is loading up the stove with wood that sticks out the top which slows the burn process by blocking the upper vents that gasify the smoke. I have seen several examples of guys using 10 or 12 inch sticks in the little stoves like flowers in a vase then lighting them. The result is a lot of smoke and negative comments about how the stove isn't "smokeless" at all.

In my test of the tiny 5.5" model I have learned that 16 ounces of pellets is about the ideal amount to use and will fit in a standard zip lock sandwich bag. Once lit they burn at this elevation for about 50 minutes uninterrupted and the stove stays hot for over 2 hours. A 40# bag of pellets at about $6.50 should make about 40 fires at a cost of about 16 cents apiece. For all intents and purposes the stove is smoke free once it comes to temp and gasifys.

Using wood is a different story as the smoke is obvious but not near as bad as a regular campfire. Here I only have western softwoods, not the eastern hardwoods that would perhaps burn cleaner. I cut firewood into 2'' sections on the band saw then cut the sections into 2'' or 3'' blocks with a hatchet. Two pieces of firewood made a helluva lot of 2'' blocks, the wood being 3 years dry by now. It was easier to start than pellets but gave off a lot more smoke in the process. Like the pellets the wood burned almost completely leaving only a small amount of ash but unlike the pellets, went completely cool an hour sooner and the wood had to be fed every 12 to 15 minutes to keep going.

Armed with what I have learned in the past couple of weeks, having a fire on the deck every evening after sunset, I have ordered a 7'' model from another manufacturer that I think will be the optimum size for a picnic table. It will require a few more pellets but the cost is still negligible and the storage and convenience make up a considerable advantage.

I wish I had these last year when Freestone and I went on a 2,000+ mile road trip to Glacier, Yellowstone and the Tetons in the fall. We stayed in 14 different campgrounds, some on real cool evenings and it would have been nice to have a little heat and light after dark. Maybe this fall in Wyoming....
 
Dammit Ive . . . your reviews always get me. First it was an InstaPot, then an AirFryer, now a mini Solo Stove. I still use the first two regularly, and am already a Solo Stove fan. Didn't know these little baby versions were out there, but agree that you can't go wrong at that price. Can't wait to try it out when the Ohuhu lands on my doorstep -
