I use these warmers all the time. To turn it off, simply disconnect the burner from the tank like you would if you were filling it with fluid.

you sound like you'd sell me timeshares

OK This is honestly one of the best reviews I've ever seen. Very clear, consise, and just great. And all in a single take too!

This thing made my life so much better when I was active duty. The only good thing I got from Wal-Mart

When it’s needed they’re nice to have . It’s like a blessing when I’m In the woods and it’s none chilling cold

Friggin' great review! To 'switch' the warmer off, simply hold it in your hands and block the air holes for a couple of minutes, or, put it in a plastic ziplock bag to starve it of oxygen (it doesn't get hot enough to melt the bag!) You can also tweak the catalyst burner and lid for a tighter fit just by pushing in the really soft metal sides.

Good review, one of the better ones...... You got more things in the review right then some of the messes out there, especially filling, capping with converter and then letting it sit for 2-3 minutes, this will build up the fuel vapor under the convert, in the small air chamber located there. I have seen so many reviews letting it sit with the converter off, this doesn’t do a thing. Also not turning it into a roaring flare when lightning, just the heat, not big flame needed to get the chemical oxidation process started, good advice. There is a review where the guy soaks the converter, to light it easier and sets it on fire with a 6-7 inch flame, roaring for several minutes, bad idea and dangerous. Ok, here are some thoughts, about that loose cap, you can squeeze the cap at the bottom, slightly, gently along the open edge to tighten the fit, I sometimes have to do this to the body of my Zippo lighter to get the insert to fit tighter, just don’t over do it, does not need much pressure. A USB lighter with light this very well and cleanly, no flame soot, there is a KZfaq guy who has started one with a broken, aka empty, lighter, just using the sparks of the flint. Sooting the catalytic converter should be avoided, i.e. too much flame, or getting lighter fuel on the converter, it will damage it with impurities, coating the platinum, and make it hard to start, less heat. I would advise rebuilding the converter, you can buy higher grade platinum impregnate materials then what comes with this. It will start easier, burns hotter, it’s also cheaper then buying a new head, about 1/2 the cost. You should let the hand warm heat up unbagged for 10 minutes upright. This will start to heat the tank, and the fuel inside, improving vaporization, increasing the heat drastically. Oil lanterns work the same way, when lighting, turn the lamp up to about 1/3 less then the light needed. In ten minutes the tank, the metal on top will heat up the oil making it flow more efficiently in the wick and increasing the size of the flame. Turing the wick up too high aka where you want it, while the oil is cold is the reason you seem to automagically get a soothed globe. I finally learned this lesson the hard way. If you can safely warm the metal tank with fuel in it, a bit, the converter will start up easier, the reason, vaporization. The bag is not only used to protect the hands from burning but also control the oxygen, it the hand warmer gets too hot, close the bag tighter, open it more for more heat. Fueling these things. I find a free syringe, no needle, from a pharmacy easier to use, even with my Zippo lighters. Just premeasured what you need from that plastic filler cup so you know the syringe numbers equivalent for the hours you need, get a small diameter leak proof bottle to hold the fuel. Personally I just loaded a few small bottles each with the exact amount of fuel needed from that filler cup, use the syringe to empty the bottle. That way I don’t have to measure it out, look at the numbers on the syringe, good for fishing or camping where the less fiddling the better, just one bottle per fillings. About the plastic filler cup, keeping up with it, the Japan, Korean made Peacock brand I believe can store the filler cup under the main cap when not in use, Peacocks are excellent hand warmer, very good fit, coming in 3 sizes baby/mini, standard and a giant that runs 24 hours. Also Whitby from the UK is a very good warmer, every thing snaps on, best of all, it has a rubber filler port on the tank’s shoulder. You can fill it by just inserting the filler tube in the port, the port self seals, no removal of the converter. I own a Whitby, yes, the same UK sea port of Dracula fame. Why is this filler port good? Well, no worries of dropping the catalytic converter loosing it on a dark ground, high grass, bottom of boat or worse in the water.

Thank you for the great video. Like you, I have had one of these for 2 or 3 years and I love it. Yes, it takes a little prep work to get going but it is worth it. I have tried a few hand warmers in the past and this is the most reliable by far and it has a decent heat output. I put mine in a small ziplock bag to put it out and it takes about 10 minutes for it to cool down.

What Landon says is true, you can pull the burner. My brothers both decided they could not deal with the smell but hated the waste as well. So they went with an electronic option, the Celestron Firecel. It only needs to be charged by micro USB, is easily turned off and back on, provides decent heat, and can in a pinch give you extra phone battery life.

I bought two of these and I have found that they are amazing for use while fishing

I recently purchased a bunch of these to use at work and I put one in every pocket . And man these work great . I found a cheaper fuel alternative here in Australia called shellite . Oh and I rebuilt the burner in one of my old zippo handwarmer with a piece of catalyst material I got from Ebay. I just took out the metal retainer took out the old one and slipped in the new then installed the metallic clip back on . Better than spending $15 for a new replacement burner.

Yep leave it in the soft bag, then put that in a plastic bag. It goes out in just a few minutes. And it's still full just needs to be re-lit. Like you say, it's not super hot, and less so in it's soft bag, it's not going to melt the plastic.

-3 below in Albany, NY this morning, could use this to walk my dog. Actually, I just need to put in a fence.

Will it fit inside a saxophone on a cold Philly New Year's morning?

its -10 real feel here in northern Massachusetts today. yesterday was -25 real feel. its brutal. I have one of these and love it. I got it for Christmas last year. I use it a lot.

Just bought one as uk gets cold this time of year,was easy to start up and I thought it would be just luke warm but I'm amazed how hot it gets really need the pouch as holding the warmer on it's own is impossible.had to take it out of my Jean's pocket as leg was getting too hot.will update on how long it lasts as I filled it to the max.thanks for the videos

I bought three of these for camping. I like it a lot.

Love these things, I have two of these larger black ones and one smaller one in white. The way I turn them off is popping out the catalytic burner with a knife and let it cool off for a few minutes, unfortunately your lighter fluid will still evaporate of course. Also a little tip is to use a butane lighter to heat up the burner, I just use a cheap Ronson flip lighter and it works great. (Nice Fahrenheit reference by the way)

*WOW THIS HAND WARMER IS LIT*

Old school! I'm a carpenter in New England and these things are clutch in the winters up here working outside

Great review! This is how a Zippo functions....Zippo hand warmers do not run on lighter fluid..in fact lighter fluid should NEVER touch the catalytic burner ot it will be ruined. ..but instead run on the "fumes of the lighter fluid" as it evaporates up from below and into the little burner head. As the fumes fill the catalytic burner material, a grey fuzzy stuff coated with a very light coating of platinum found it the head that pops off when filling.....the burner begins to glow like an ember when a match is put to it. The ember...which looks almost like the tip of a cigar in a dark room will then continues to glow with heat, as it consumes the fumes which constantly rise up from the bottom fuel holder which you fill. When all the fuel has evaporated, often 12 to 20 hours..the burner simply goes out. Your cars converter has heat from the engine flow over tiny platinum balls found in your card converter..this burns off engine odors. The hand warmer operates almost the same way.

Thank you very much Moe Sizlak 😉👍

i live in ontario canada.. it gets as low as -35 celsius on the rough days of winter. i do collect zippos, i have a few 8 and 16 hour hand warmers. i dont usually carry them to walk but they are handy in the truck if it wont start or something like that. i rather the 8 hour ones because unless you are ice fishing or hunting its rare to need it for a full 16 hours. i got a mini 5oz jerry can i carry spare fluid in, if you have one buy a small flask for extra fuel

I haven’t tried putting it in a zip lock bag but I could see where you could conserve fuel that way. Another method to stop the heat is to quickly remove the small catalytic/burner part and place it on a plate or saucer to cool.

I have warmers that are a vinyl bag with a liquid inside that I believe is a super saturated salt solution. There is a metal disc inside that you snap and the solution begins to crystallize which gives off heat. To reuse it, you just need to boil it

It's a hand warmer not a hand hotter... HA I love it. I agree this is probably one of the best solutions out there. I've seen people put a line on it and wear it like a necklace and that makes sense to have it lay on your chest to warm you. Great review Nick!

Best and most thorough review for zippo portable hand warmer! ❤️👍🏼🙏 I use without the plastic pitcher by putting the tip of zippo into the opening, give it three or four squeezes. This provides an easier lighting (also mine came without the pitcher🤷‍♀️😅)

so leisure suit larry does youtube vids now?

Nick- i love these reviews on gear that I have no experience with. I have seen these hand warmers on MD many times. Seems like the best improvement would be a filler tube on the hand warmer itself that you can see. Thanks for the info.

Zippo has a new 6 hr rechargeable battery hand warmer and it works as a small power bank.

So much confusion here - 1) you can easily turn it off - 1) place it in a ziplock inside its cover and it will go out it < 10 min or 2) on your way inside place the bottom of it in a snow bank / or next to a piece of ice and it will cold shock and “turn off” 2) you definitely don’t need, (and should NOT apply “a lot of flame” kiss the sides of the catalyst for ~ 5 sec each and your done, doing more will wear out your catalyst and decrease function. Try instead filling it with fluid, completely closing it, catalyst and cap, in bag for ~ 3-4 minutes keeping it warm to start evaporation and it will light quickly. I use a USB lighter only with mine. 3) If you get a better version, (not a zippo) with a few tweaks it will definitely! get so warm that you cannot hold it in you bare hands 4) Use camp fuel/ white gas/Naptha and save your money. Add 30ml of essential oil of your choice to 1 L of fuel and the odor is much improved. 5) squeeze the cap tightly and it will fit better 6) Try an s-Boston and you will be far happier -

Hi Nick. I went to Dollar Tree and got a container that has a rubber seal. When I get to work I put it in the container and close up the lid. It takes about 20ish minutes and then it goes out. I too didn't trust the plastic bag thing but the container is perfectly safe. And I went and got the smaller one. I myself like the small one for work and the big one for camping. Just me though. Hope this helps . Cheers

“Combustable Oompft” perfect review 😂

Thought about getting one of those for my car, let it burning overnight so the inside of my windshield isn't covered in frost when I get to it in the morning (yes, the inside of my windshield is covered in ice most mornings for a few months per year. And I still love being Canadian) Wondering if it would be effective, and about the fumes... having this thing lit in a closed container for 12+ hours, would I need to "air out" the car before sitting in? Does anyone have experience with it in this sort of situation?

You CAN turn it off by simply removing the burner and letting the heater cool down. Pop the burner back on and relight when you want to use it again. Simple and effective and saves fuel.

I like the rechargeable zippo hand warmer power bank much better.

Thank you mayor Quimby of Springfield for this awesome review

Gotta love that Fahrenheit 451 reference!

I have a couple of these! They were my grandpas and they are old. The sucky part is I have never had that pouring spout so it’s always a guessing game when I’m filling it up.

This guys voice is hilarious xD

These are great ! Had s vintage one as a kid (Not sure if it was a zippo) Have a zippo now .i work outside heavy construction keep it in a chest pocket plus chem foot warmers. Makes temps tolerable Great review nick !!

I got one of these guys. And I do not use it nearly as often as I should. They really are amazing. Cool review! Side note it's been anywhere from 0°F to 10°F for about a week an a half now where I live. I'd definitely recommend this. The chemical ones are nice for the high temps they reach but I fully agree that the reusability of the zippo warmer is where it's at.

i bought one of these . i opened it up to use and they forgot to install the damn catalyst burner .

Quick info on this that has probably been said 100 times so I'll be brief. 1. Turn off by popping the part you light off (not with fingers) they are made to be disconnected and replaced as needed.However evaporation is still a thing so keep that in mind. 2. Squeeze lid and it will tighten to your liking. 3. Buy the small ones, one for both hands. More heat because less space and metal to heat using exactly the same mechanism.. Ie same heat out put as the big ones. 4.the small ones do get hot enough that you can't hold them without a lot of pain bagless but the option is there when your hands are already very cold like if you need to work but then can grab one when your hands are too cold. 5.the small ones can stand up like a Zippo lighter the big one is round top and bottom. 6. They do take continuous flame for much longer than he showed in my experience so a Zippo lighter is a good companion. Anyone with further questions feel free to ask and if I get the notification I'll answer I have a big and 2 small ones.

With the chemical hand warmers it's easy to just open the package and activate it, they get nice and hot and stay that way for hours. I had the zippo and you don't know if it's working half the time and doesn't give you the instant warmth you need. Plus if you need the chemical one every day cost will be a issue. Milwaukee tools has battery powered gloves and jackets that are awesome. Pricey but if you use them everyday for 4 months it will pay for it self in 1 winter

Our high this entire weekend is -6 in MN. Never explored hand warmers for EDC, only ever used them during deer season in the stand. I usually rock a nice pair of leather gloves and deal with cold hands sometimes. Might have to look into this a bit more.

I use two for snowboarding, when it gets real cold (-20c) i slip one between inner and outer gloves in the palm, leaves the hand surprisingly mobile, though they might be the 6 hour version

I don’t like hand warmers that use lighter fluid and can’t be turned off immediately. For safety reasons. I just got the Celestron ThermoTank. I have been loving it. A nice rechargeable hand warmer. Have you tried the Zippo rechargeable hand warmers? If you like lighter fluid based handler warmers than this Zippo is a great choice. Great review Nick!

Another great review Nick, I have a couple of these but more of the knives you’ve reviewed. Keep it up.

Small ones are good for hand pockets...the bigger one is great to tuck in an inside coat pocket

I like the fact that there's very little waste with this. Only thing you're throwing away is the can for the lighter fluid once you've used it all. Depending on how much you use it, 2 cans usually last me the whole winter.

love mine, the only peeve is that the lid would come loose when it got up to temperature and tend to fall off so i used HVAC tape to hold it the body, no residue and no melt.

To turn it off... Turn it upside down and tap it on something so that the catalyst comes off and you can hear it rattling around inside the case. Leave it in the bag and it will extinguish itself fairly quickly.

Great review Nick!!

Get a Zippo fuel canister or two for your keychain

6:55 about the upper lid, you can press it down do narrow it and recap it for provide more holding strength on to the body case :D

I just got one of these and I agree with what you said on your review. The smell is familiar to anyone who uses or has used a Zippo lighter. Invariably, I have fluid run out and it does evaporate quickly but be sure and read directions prior to use. I didn't think it was too warm either. I took the bag off and touched it to my cheek and it was uncomfy to a sensitive face. Hands no problem. They make a 6 hr. version and the 12 hr. one like yours (and mine). About 13 hogs at Wally World. Oh, and Zippo lighter fluid is not always available but they say Ronsonol is OK. Uh, Zippo now owns Ronsonol, so buy the least expensive.

I like that peanut lighter more than the warmer. Never seen one of those before. I have to get one.

Now we all know who was fighting the Z-Hunter in your pocket! 😉😜🤣🤣🤣🤣 I recommend it’s official title be changed to: “Pocket Pecker Wormer” in order to stay current! 🤯🤪

Got one in each car!!! Just smart....4 degrees, dang come to Alaska where it is -213 degrees, well -12....damn cold anyway.

Is it normal for the catalytic burner to rattle when you shake it?

How about fleece-lined mittens?

Great review! Loved the Fahrenheit 451 reference haha! I thought the same thing when I started carrying one of these

If i need a hand warmer, I tend to want the little disposable ones (I know, waste) due to being able to stick them in a glove. If it hits -30C, I'm not going to want to take my hand out of my glove to stick in a warm pocket. It's cool that there are reusable options out there though.

Just got one ..impressed...works well...

Temperature of the handwarmer is based on how much air it's getting. if you have it slightly out of the bag it will get much hotter. My method of turning it off, I put the heater and cover into a plastic bag and ziploc it shut. it goes out quickly

Take the burner cover off and put the fuel holder in a glass jar with lid to seal out oxygen. Can't catch on fire in a jar.

7:14 IT CAN BE TURNED OFF despite what the instructions say, just remove the burner. Try it and wait for 2 or 3 minutes and you'll notice the temperature drop.

Zippo makes an aluminum fule can ester that holds s refill ten bucks and Zippo fluid get some !

You should be in one of those old Gangster movies with Jimmy Cagney.

Just got mine and honestly I was surprised at how hot it gets. I left it out for a few minutes after lighting and then physically couldn't touch it to get it into the bag 😂

I didn't even know that existed. Excellent

It's a Zippo use a Zippo lighter to light it and pre heat it if it is cold on a car lets say ! Always carry a Zippo brass lighter !!! Armor !!!

3 hours i get out of it, used it 3 times now, what do i do wrong?

After reading all the below comments, I think there are a couple or three folks who would consider using gasoline. BTW, do not do that.

canadian here. try the electronic USB hand warmers. On off switch and you can charge your phone off it

Good gift for your mailman

Thanks, very informative. I have one ( Not zippo)that i bought at a garage sale, would it work the same? I've never owned or use one.

hey Nick, might wanna check out the Zippo website again! Saw a re-usable hand warmer that doesn't use fluid and flame, also acts as a power bank from what i understand.

Great honest review

I just bought some USB rechargeable handwarmers that work well. Plus they double as portable chargers. FourHeart brand on amazon.

i bought this warmer last week and only started to use couple time. The warmer can only last about 2 hours for the amount of fluid that recommended by the instructions? How can i slow it down ? Secondly the warmer must be put inside the pouch because it was very hot sometimes.

My wife has cold hands all the time and has been using one for over a year 24/7/365. My filler container is like a narrow bowl with a long neck. Care is needed so I don't knock it over. Lot of lighter fluid on the table. Don't ask how I know...

You did briefly mention the lighter fluid smell. Is that an issue in everyday use? Or only when refilling it?

I always wondered how these hand warmers worked. Stupid me didn't Google it though...well not stupid. I figured you'd do some sort of review one day Nick :)

If you overfill it, then it's a better product all around. It catches on fire when you start it, but it calms down.

Does it leak?

Zippo makes an electronic one now, if you are looking for one with an off switch.

You can smother it fairly easy with just your hands.

What's the build quality like.? I've heard they are now made in Taiwan not the USA..!

I think I'd like to see a huge version of this to heat a room

How long do your catalytic burners last you? They claim 70 tanks, but I've been reading that since they changed the style to what is in this video, they aren't lasting as long

When is the review of the mini tolk coming. Thinking of getting one.

I just got one for Xmas. Can you turn it off or let it run out of fuel ?

actually its way colder where i'm at and what i do is not good at all i just get used to the cold and after a couple of minutes you dont feel the cold any more nor your finger tip but how care no but seriously here up in canada its -25 degree c or - 13 f for week at the time so we just are used to it and put on gloves and really after couple of day you get to a point where you just are ok with it so all that to say nothing helpful

4 degrees. You poor warm Americans. -31c in Northern Canada today. About -42f with the wind chill factor. Good day to stay inside and watch Nick’s reviews.

10:02 Great reference!! 👏 😂😂😂😂😂😂

I got one of these, figured I should stop using the chemical heaters that only work half the time. The one I got keeps warm, unless it is out of the bag, then it becomes too hot to touch for more than a second or two. Must be all the extra oxygen or something. At first, I was a little disappointed that it cant be switched off after being lit, until I realized how cheap it is to operate. Let the thing burn itself out- it only costs pennies to run for 8 hours or so. I'm not too well off, but I can at least afford to let this thing heat the inside of a drawer for a few hours.

I’m not sure I understand what is going on with this device. The user lights the wick with a flame, but it’s not burning for twelve hours? If there is no flame, how is it creating heat?

❤ love it send us some to share
