The air activated packs can be turned off and on by sealing them in a layer or two of ziplock bags, with the air mostly squeezed out.
I used to do that for a half hour walking commute in the winter. I could get a week out of a package of handwarmers, instead of going though 5 pairs a week.
Also good for hiking when you start out on a cold morning and only need them for a bit of a start....and similar situations.

I have accidentally packed them up in my sleeping bag during over nighters and found they work the next night too!

I'll put a plug in for one of my favorite pieces of backpacking gear that you can use these hand warmers in.
https://www.outdoorresearch.com/en/mens-versaliner.html
Great set of fleece gloves and water proof shells that you can use separately depending on conditions. They have a zippered pocket for hand warmers. Total weight is under three ounces for a size large. Perfect for three season PNW use.

These are awesome!
I have used them for a couple of years now. Extremely versatile, and they work well with the handwarmers (or without). I bought a second pair just in case they stop making them, and I never do that.
The only down side is they are not "e-touch" compatible on the fingertips. A sad oversight. They must be removed to use your phone or touch GPS etc. Although I have altered my pair with conductive thread in one of the fingertips to work with touch screens.

Why not use a Zippo handwarmer? The large one will go all night in your sleeping bag.

Aren't those rather heavy? Especially if using them for handwarmers and foot warmers, which would require 4 of them. Maybe if you just used one to warm your sleeping bag, it would be a good choice?

Given that they are refillable - I don't see what the weight issue is. They are not flexible, so they're not a boot warmer.
Anyways, just wondering. I use them and like them.

The zippo's are great and will work with high quality white gas. They can be used to "pre-warm" boots -- which is very helpful in the morning -- but they can't be worn "in the boot"
The Zippo's and all oxygen consuming warmers contain all sorts of warnings about not using them while sleeping -- just like stoves and tents contain all sorts of warnings about never using a stove inside a tent -- which are routinely ignored by winter campers.

I have a couple Zippo handwarmers that I use for winter flyfishing.
I feel they work well enough with the "odorless" Zippo fuel, but are no warmer than the disposable type. I do not use the Ronsonol lighter fluid as that stuff has a pretty strong odor.
2 questions for the audience:
1) Do they work better (warmer) with white gas?
2) Does anyone know of a good inexpensive source for the "catalytic" burner elements on the top? I wouldn't mind buying a half dozen as they do wear out with use.

I see Amazon has the elements for $6- 7 each.
How long do the elements last? Between the intial cost, weight for packing a few of these, carrying extra "special" fuel, replacing elements, lack of flexibility in placement due to bulk and rigidity( I like to slip the chem rxn type in socks and hats and back of gloves at various times), I am not seeing a convincing argument to switch. What am I missing?

Here is a write up on Zippo warmers.
Yes they work really well with Coleman fuel. They also work with alcohol - but I think they smell funny.
They don't get hot enough to melt a sandwich bag.
Supposedly the catalytic element is good for ~80 burns - but I don't count and I've never had one wear out. You can buy replacements online.
Better than a pee bottle if you don't have to pee.
I'd have to put one in a box with a CO alarm to see if they create enough CO to be concerned about.

I put one in a 2 gallon ziplock bag along with a First Alert CO detector (400 ppm). After 14 minutes the CO alarm sounded. I removed the Zippo and found it still running. The Zippo was running on Coleman camp fuel.
So what did I learn? The Zippo will eventually deplete the Oxygen in the bag but continue to combust inefficiently - producing enough Carbon Monoxide to trip the detector. (I did this experiment with a votive candle, and the candle went out after 4 minutes without triggering the detector).
So the Zippo will produce CO if starved for O2. Lesson: don't sleep in a plastic bag with a running Zippo.
