Zippo Handwarmer - Chrome

I'm not kidding - this lasted a little over 48 hours on one fill (to the brim) of lighter fluid. I've tried both main types of fluid available in our area now, (Zippo's own black tin and Swan's yellow one), & I've not noticed the slightest difference - except the price of course!

When I first used the Zippo handwarmer, I couldn't get it to stay lit more than a few minutes, but the secret I've found is 3-fold:

1) Fill with the lighter fluid and leave it for a few minutes (with the catalyst burner-head in place) to allow the fumes to move around the product (so there are no air "gaps") which can cause it to go out;
2) Heat the burner-head properly on each of its flat surfaces with a lighter (not the top of the yellow flame or it will soot - use the top of the blue inner) when you're lighting it, even after it's obviously "lit" (about 15 seconds) - this helps to vapourise the gases and sustain the ignition (you should NOT apply lighter fluid to the burner-head itself - it will flame and damage the head);
3) Put the metal lid onto the lit burner and put it into its soft, draw-string case and into your pocket. Don't ask me how (I'm not a combustion expert) but this actually seems to encourage it to work. I DO know that it doesn't require additional oxygen to work - whatever is available in your pocket is clearly sufficient.

Obviously, if you don't want it to last for 2 days and 2 nights constantly, then don't fill it up to the brim. As mentioned by others, Zippo do supply a nifty little container clearly marked for showing what fill one needs for 6 or 12 hours of heat.

For instant heat I use the clicker-pads (and yes, you can recharge them very effectively with a microwave) but for long-term sustainability, the Zippo is surely hard to beat.

Unlike other hand warmers this one does last for a long time. Make sure you fill it up to the maximum level when lighting it up for the first time. It stays lukewarm in the cover so you can put it inside a jacket's inside pocket without any worries. And when you need it you can pull it out, it is toasty without the cover. I normally use it in my morning commute, once indoors, I put it back in its bag and tuck it inside my jacket.

Peacock makes the best hand warmers however they are a bit pricey. These are made in the same peacock factories however their finish is a bit inferior to the ones peacock sells by its own brand name but then these are also more affordable.

This was the last of 3 different types of hand warmers i have tried and in my opinion it provides the best value for money and does the best job.

I have tried the Charcoal hand warmers which burn a stick of charcoal they tend to last about 4-5 hours at best and they obviously have a very strong burning smell which is not ideal if you work around other people etc, they do get very hot maybe too hot at times.

next i tried the small Sodium Acetate hand warmers which is contained in a small plastic pouch which you snap a small metal disc and a chemical reaction generates heat, now these don't get much more than luke warm and last for less than an hour, and if you don't recharge them correctly they become useless.

then i purchased one of these Zippo hand warmers, i had high hopes from the start purely based on the reputation they have for their lighters, and they have not let the quality slip with the hand warmer, you can pick up 250ml of fuel for £3-£4 which should last you a good 2-3 weeks depending on how often you use the hand warmer, the warmer itself can get too hot to touch but with it in its pouch it is the ideal temperature, its easy to refill using the measuring jug that is provided, you simply remove the burner filament and pour the fuel in using the supplied measuring jug, now this listing says it last up to 12 hours, mine today lasted over 19 hours i lit it at 4:30 am before i left for work and it was still well alight at 2330 that evening, it burns with no flame virtually odourless just the usual smell of Zippo fluid, to stop the hand warmer simply use a tool the remove the hot filament and it will cool within 2-3 minutes.

Again in my opinion out of the 3 types i have tried this is by far the best i've used and i have no doubt it will last for years to come.
