Zippo - Hand Warmer, 12 Hours Heat, Refillable with Lighter Fuel, Reusable, Pocket Warmer, Highly Polished Chrome

After reading some mixed reviews I wanted to give a realistic view on this device. Firstly I was let down by another non amazon supplier on the Zippo Fluid so ended up buying Coleman fuel from Cotswold with a little trepidation! The good news is that Coleman fuel works a treat and for just £9 a litre its cheap. I followed the instructions precisely and on the first use carefully put 12 hours of fuel in and then importantly left it upright for 5 minutes for the vapour to spread. I then lit the top of the catalyser with a butane lighter for about 10 - 15 seconds. Now initially it was just lukewarm and I was worried that was as good as it might get..... but after about 20 minutes was getting hotter nicely while still in the sock, now what I didn't realise is that if you open the sock up it lets in more oxygen and gets hotter and if you pull the sock down a bit it gets really hot, in fact too hot to touch the metal. It seems to work really well in a pocket with the top of the sock cord not too tight.The effect of being in a coat or trouser pocket seems to insulate the heat nicely.I did a heat test using a baking thermometer on the outside of the metal case and it reached over 70 deg Celsius opened right up so all the vents showed with the sock just half covering and then with the sock completely over it and the cord loose went back to about 45 Deg. You can see the catalyst glowing orange in the dark and if you blow on it, its glows more brightly hence the heat being controlled via oxygen access. Its now nice and warm still after 11 hours of lighting. If you buy Coleman fuel it has a large neck on the bottle so I made a bigger hole with a modelling knife in the little small filler bottle that comes with the Handwarmer. It appears that the Zippo 125 ml fuel has a small spout which is probably easier. The Coleman fuel has a slight odor close up but isn't noticeable once the warmer is in a pocket and people say the same about Zippo fuel.Its a nice tactile feel with the curved edges and makes it feel very slim, it seems well made and for the price will be good value compared to the chemical hand warmers I also use which still have there uses in gloves and shoes (The 12 hour Zippo is just a little too large)This Zippo is going to be just great for Winter Cycling. Motorbiking, Skiing and Winter walks - Happy Days!!

Used it on frosty site mornings and late drives—stays warm for hours without needing constant attention. Metal build feels solid, not flimsy, and the refill system’s straightforward once you’ve done it once. 6 or 12-hour burn options give flexibility depending on the day, and the heat’s steady—not patchy or short-lived like some disposables. No flame, no smell—just clean warmth. Fits in a pocket or glove easily, and the pouch helps regulate temp. If you want reliable heat that doesn’t quit halfway through the shift, this Zippo’s a proper bit of kit.

I've only ever used the reusable chemical hand warmers in the past, and they don't come close to this.Filling is easy with the included plastic filler, and I filled it half way to test. Others have complained that it can be difficult to light for the first couple of uses but that wasn't my experience.It was easy to light with a tea light candle (using torch style burners isn't recommended) and it took a good hour to get up to full steam. Placing it into its pouch and then into a pocket has limited benefit, due to (what I could gather) limited oxygen supply to the burner and so placing it into the kangaroo pocket on a hoodie without the pouch worked best for me.It burned longer than advertised, and it does get hot to the touch if supplied with enough oxygen. Zippo claim that it's odourless, but in my test there was a very clear smell of the lighter fluid which doesn't bother me in the slightest, but is worth noting.Also worth noting, is that the burner part is a consumable and will require replacement after around 70 burns according to Zippo. I've bought two in anticipation of this and they can be had from Amazon for £5 or so.Overall, its definitely worth having if you spend time outdoors or indeed any cold environment and I found that placing it against the torso has a bigger benefit than against an extremity.

I have had this hand warmer for a couple of months. I use when I play winter golf. It gets quite warm when in its protective pouch . When out of its pouch it gets almost to warm to touch. Filling and lighting the hand warmer was done in less than 5 minutes and it lasted way longer than my round even when only half filled.Problems I have had were that the catalytic burner occasionally came loose during my round and so burner went “out “. About 5 weeks in the ‘ copper washer’ came out of the catalytic burner . I did push back in but the reliability didn’t seem to be there. So I had to purchase a replacement burner . Lately I have had a problem with warmer going out during my round. Not sure if this is to do with the fact that my rain gear is windproof and maybe burner not getting enough air when in my pocket.Despite all this I do like the Zippo hand warmer. It has a satisfying feel about it .
