I’d like to start by saying the warmer itself is literally the most amazing thing ever and I’m obsessed with it. I know a lot of the reviewers have had some issues and I’ve had some as well, but after doing some research on Reddit, I have came across some things I think would be great advice on “hacks” and getting the most out of your hand warmer. First things first, your hand warmer should NEVER catch on fire like I’ve seen some of your reviews do. If it does this, this means you are either over filling your warmer or you still have a decent amount of residual fuel left over from your last use and adding more fuel will cause it to combust. If you’re not sure if your warmer still has fluid, always try lighting it and check for warmth from the burner before adding fuel. Next, you can put your warmer out by removing the burner from the device and placing it on a safe spot, like I use my granite countertop! If you still have fuel left over, you can save it from evaporating by purchasing or cutting a latex tube, bike tube, latex glove, whatever snug tube shaped device to wrap around the hole that you dispense fuel into. This will create an airtight seal and prevent your fuel from evaporating when not in use! The next part is my favorite. So in one of the threads I found on Reddit, someone advised the issue that is the zippo burner itself. You can buy zippo burner replacements in stores or on Amazon for $7 usually. Zippo claims you can get 80 burns before getting a replacement but as many of you already know or are finding out, the thin little strip of catalytic burning platinum starts to loose it’s strength after a couple lights or so. I’ve seen this vary from person to person. I’ve seen people suggest to fluff it up inside, but don’t do that, this can cause the platinum particles to loosen up and dispense around the air you are breathing in and I’m sure that’s not healthy… LOL. The best thing I have seen, that not only saves money and works amazingly, but will last you probably the rest of your life and eliminate the need to buy replacement burners EVER! There is a product on Amazon called “Platinum Bright Embers” and is the same material used in the burners zippo sells. These are used mainly for people who own gas fireplaces and want to create the aesthetic of burning embers falling off the wood in their fireplace. But if you own a zippo hand warmer… you can take your old cr*ppy zippo burner off of your hand warmer, take it outside and use a toothpick, skewer, whatever you can use, to push out the old platinum. Then you open your new bag of platinum bright embers and pull out one of the little swabs and stuff it tightly in place on your old burner, bam, good as new! In fact better than new! If you see in my photos, this thing GLOWS bright as hell only after a few licks from your lighter’s flame! Don’t be alarmed though, once you place the top back on your hand warmer, the holes will cut a lot of the oxygen off and it will not be as bright anymore, and then obviously I really recommend you place your hand warmer in the fabric bag it comes with, because your hand warmer is gonna get HOT. I also forgot to mention, the embers are on sale on Amazon for like $25-30 depending on who you buy it from, but all you have to do is search Platinum Bright Embers. This has been the best discovery for my hand warmer and it’s been keeping my cold *ss warm so far! Typically, I do not fill my tank to the 12 hour mark, I usually only fill it halfway and because of this and keeping it in the bag and the strong thick layer of platinum I put in the burner, my hand warmer has been lasting way over 12 hours with only half the tank filled. Sometimes I get 20 hours and I’m honestly surprised! Lastly, you can attach a lanyard to your hand Warner bag and wear it to warm your torso up, in doing this, your torso will help warm up your limbs. I really really hope this helps anyone! Best decision I’ve made!
