12 Hour Refillable Hand Warmer

This thing rocks. Stays hot for 12 hours. Very happy. It seems like magic. I can't even see or feel a flame.

Great little hand warmers. I have some of the other well known brand, which work well, but the Zippo, although somewhat slimmer, burns longer on a fill. I even tried adding 50% more fuel to the other brand and the zippo still burned longer. The heat is not as intense as the other brand but adequate to keep your hands warm. The first time you use the zippo it won't last quite as long. After the first burn you'll get a whole workday of heat.

I really didn't expect it to work so well. I work in construction driving a small opened excavator. And this has helped me alot really warms up and lasts a pretty long time. Definitely will be keeping this close by.

I bought two of these hand warmers. I am impressed at the versatility of this unit. I use it in my jacket pocket, on my neck, hip, and abdomen. The felt pouch is super comfortable and the temperature is excellent. If you want it hot, just take it out of the pouch and put it where you need it. Even outside the pouch it won't get too hot to burn you or anything. I live in Montana where it gets -40 F in some places. I like to use it on my shoulder or hip when I'm at work, On a full tank, this has lasted me easily 18 hours and Im using the big yellow bottle of Ronsonal lighter fluid that is easily 10 years old. The down side. After 10 or so uses, I have found the catalytic burner to become temperamental. I have to use a butane lighter to activate. You know the warmer is on when it has a nice amber glow coming from it. The burner on mine came with only a little platinum (active ingredient) and so it does go out. after activating. I found the trick was to keep the lid off for a few minutes so the burner gets enough oxygen to be self sustaining, then Im ready to go for the whole day. I prefer non battery warmers because I don't like lithium batteries so close to me and they only last a couple hours. So there are hacks to make this warmer better. One you can just buy another burner for like 10 bucks or be crafty. I choose crafty. There are YouTube videos on how to improve this warmer. It involves buying the "platinum bright embers." and refilling" your burner. It's crazy easy. you just need tweezers and maybe some scissors. I got a good amount of the platinum embers off a fireplace website for a much better price than amazon. This orange unit has 25 stamped on the burner. That means that it made in 2025. The silver one says 2022 on it and it works better. Pattern? Unknown. I would buy these again. I can't wait till the Platinum embers come in so I can upgrade my warmer So my advice to you is GET IT. But order 2. If one has a bad burner, return it. It's worth keeping both if they have good burners. Oh don't forget you need lighter fluid. Grab a bottle at Wally World. a 12oz bottle was 4 bucks. You will need a zippo or a butane lighter. I recommend a butane torch. It lights the burner quickly and effectively. Just know that butane lighters are also a science. They don't work in cold temps and high altitude. So a good old fashioned zippo might be called for if you are in an extreme area.

Works well. Lasted all day.

I love this unit. Heats up quickly and Stays warm for a lot more than 12 hrs. I use the fill container to fill it. I’ll use it for 5-10 hours then put it and its cloth bag in a ziploc bag to cut off the oxygen and place it in a safe place and it quickly gets cool and goes out. I do not refill it unless it runs out. The bead came off of the string but I just tie it like a shoe lace. Love this unit. Ordered a second one. This way when my wife steals one I still have one.

So it’s always tough for me to shop for anything heat related living in one of the coldest states in the country. I always try to look for reviews from other cold states as frequently I’ll be reading a review and they will mention that it’s good for cold nights in Texas. Sorry but that doesn’t help us Minnesotans! So currently it’s -15 below air temperature and -35 with wind chill and this thing is staying warm. I left it outside for about an hour to see if the cold would put it out or frost it up but it stayed warm to the touch and didn’t get cold to the touch which was impressive. Brought it back inside and it warmed up again within minutes. I can’t say it gets really hot when it’s inside the pouch because the pouch insulated the heat a lot but if you touch the metal directly then it can get pretty hot, especially when it’s outside the pouch and has easy access to oxygen. The problems I’ve noticed is that when I touch the metal to get heat it will cool down fairly quickly then I’d have to wait until it heats up again. Another problem is that this functions by a chemical reaction that requires oxygen for it to work and also gives off carbon monoxide. So I wouldn’t recommend this for staying inside closed pockets or gloves because it needs that access to oxygen and using it inside enclosed areas could also be harmful due to the carbon monoxide. So it needs ventilation in order to function both to get the heat and also for your potential health. Next is the cover that goes over the burner comes off really easily. I feel like it should be more secure but it comes off super easily and could certainly be inconvient during active use or trying to use it upside down. The final problem I’ve noticed is from what I understand it has to remain upright so the lighter fluid won’t leak onto the burner part. I haven’t tried using it upside down however so I can’t confirm that it works or doesn’t. Overall it does what it claims so far but there could be better options out there for you that don’t require the ventilation and can be used a little more actively. It is a good heat source but it doesn’t blow away the other options out there such as the hand warmer pouches or battery powered hand warmers. I would say it can be a lot warmer but it comes with other drawbacks, if all you care about is the heat part then it’s worth a shot.

Love it, works great. Nice, comfortable heat for hours.
