Platinum Catalyst Pad
1.25 sq inch (1.25"x1", no springs, yield: 2 regular spring refills). Each price increment adds one one pad to your order, EG: $14.93 means you are ordering 3 pads. Catalyst: Do not breath dust from particles, wash hands after handling. How much catalyst you place in a spring is a subjective preference. In a large spring such as an S-Boston or Jon-e GI, one and one half pads can be used to fill the 135 spring, and two can be used to fill the 165 spring. In a Zippo a half pad is recommended to achieve temps around 135F, but some users will use 2/3 of a pad to get more heat. Recommendations made in previous videos may be superseded by newer video tutorials.

Large Catalyst
Platinum Catalyst, approx 16 sq in. (rebuild approx 24 catalyst heads). Catalyst: Do not breath dust from particles, wash hands after handling. How much catalyst you place in a spring is a subjective preference. In a large spring such as an S-Boston or Jon-e GI, pad size of 1.5x1.5" can be used to fill the 135 spring, and 1.5x2" the 165 spring. In a Zippo a pad size of 1.25x0.5" is recommended, but some users will use 1.25x.75" to get more heat. (Recommendations made in previous videos may be superseded by newer video tutorials made during S04.)

Empty Spring
Can be stuffed with catalyst to rebuild old handwarmer catalyst heads. This spring is Stainless, and just the right size to fit all standard size handwarmer heads with a 35mm length snug fit (to ensure it stays in place ) while the minimum amount of coil compression promotes the maximum amount of fumes to reach the catalyst: to promote optimum exothermic reaction. We finally bought a case of these from the factory, which has resulted in a significant price reduction as reflected below. Each price increment adds one spring, EG: $2.43 means you are ordering 3 springs. How much catalyst you place in a spring is a subjective preference. In a large spring such as an S-Boston or Jon-e GI, one pad can be used to fill the spring. In a Zippo a half pad is recommended, but some users will use 2/3 of a pad to get more heat. Recommendations made in previous videos may be superseded by newer video tutorials.

OUT OF STOCK: Catalyst Insertion Tweezers (Do Not Order)
Optimal design for inserting platinum catalyst pads into springs. These SS anti static tweezers have flat spade tips, and 30mm leads on them with shoulders that stop your insertion at the optimal length and prevents pushing the catalyst material out past the far side of the spring. They are wide enough to squeeze the entire pad and compress it to facilitate sliding the catalyst into the spring without fragmenting it.

Carbon Felt Strip kit:
1 strip per kit that can be cut into 2 pieces as shown below. Use: Place on top of cotton (at bottom of neck on handwarmer reservoir) to prevent charring of cotton packing. Yield: 1 strip will allow for modification to 2 handwarmers. Quantity Pricing below (if you need more than 2 kits then order the pad instead as it is better value for larger quantity). Note: we often will get an order for both a CF Pad, and some strips, which really does not make sense. The pad, and the strips are the same material, if you buy a pad, you can cut your strips from it. The strips are meant for users that just want to place a barrier strip on the top of their reservoir for one or two handwarmers, and therefore do not need a whole pad. Each price increment adds one strip kit, EG: $2.92 means you are ordering enough to modify 4 handwarmers.

Carbon Felt Pad.
Weight: 10g. 30 sq in pad (approx 5" x 6") can be cut into strips and used for repacking or rebuilding a complete handwarmer reservoir (generally done for odor mitigation or replacing old and contaminated cotton packing), or individual strips can be used to protect the top of the cotton in multiple existing handwarmers (Yield: single layer will protect approx 20 handwarmers, use double layer if you remove charred cotton before inserting the carbon felt). Each price increment adds one pad, EG: $8.92 means you are ordering 2 pads.

Letterpost Combo Kits
Letterpost Combo Kits
One of the things we see happen often when filling an order is the order contains one or two items that take the order from qualify from the cheapest postal rate (Letterpost), and bumps it up to the next level (Small Packet Air for USA, and Expedited Parcel for Canada). This is reasonable for larger orders, where an additional $6.00 is a small percentage of the total, but may not be what the buyer intended when they added 2 extra springs, etc. The following combo kits are meant to make ordering easier by combining some of the most popular items into a single discounted order that receives free shipping for USA and Canada (shipping will be reduced for International orders by $2.50). Like regular orders, Payal fees of $.30 cents plus 2.9% are added to payment request for USA/International orders. NOTE *Adding any other items to a kit will increase shipping cost and fulfillment time.
Kit #1:
Bulk kit, regular handwarmers: Large catalyst pad, carbon felt pad, 4 regular springs

Red Star Handwarmer
This Chinese made handwarmer caught our attention when we noticed the burner design that resembles the original Jon-e design. So we grabbed a sample, and tested it. Unfortunately it did not perform like a Jon-e, in fact it took quite awhile to light it, and when we did, it kept going out, and did not get very hot. So we took the rather strange looking catalyst screen out, and it seemed to be filled with some sort of powder (as seen in video). We then did a few mod's. We put a carbon felt strip at the top of the reservoir, and then placed an entire catalyst pad into a large diameter spring (the same diameter as a Jon-e Giant, but shorter to fit this burner head). This seemed to make a difference, and we were able to achieve temps around 160F. We have not tested the total burn time yet, but with the smaller reservoir size, and the higher temperatures with the high density of catalyst material, we anticipate burn times around 6 hours.Time will tell if this unit can function as a better Zippo replacement. This listing is for a value-added item: the handwarmer with carbon felt strip, and full catalyst pad (with spring), installed in the burner head. Also includes the pouch, and the original burner catalyst. There is a video about this unit in our Youtube channel.

Pre-Orders: 10,000MAh Modified Electronic Handwarmer
Electronic handwarmers a great if you only need a couple of hours of warmth. Compounding the problem is the fact the majority of those sold on Amazon and from China fall way short of their inflated capacity claims. Drawing at least 2.5A at 60C, you would expect to get almost 4 hours from the highest heat setting of 60C. However, the reality of these handwarmers is their capacity is around half of what they claim (as seen in the video below). The one that is commonly advertised as a 10,000MAh unit has a form factor that makes it capable of holding the Tesla 21700 cells after some modifications with a dremel and some spot welding. This brings that handwarmer up to the actual 10,000 MAh rating. This is a pre-order selection so we can get an idea if there is any interest in this and build them accordingly. If you select this item, you will not receive a payment request for it until they are available and ready to ship. In addition to the handwarmer function, this unit also features a USB power port that allows it to function as a Power Bank for charging phones (as shown by the capacity test in the picture below).

Handwarmers S04E11: Using Tesla Cells, test, review, and modify a 10 amp electronic handwarmer
5,000MAh Modified Electronic LED Handwarmer/flashlight
It stands to reason, the best device for warming your pocket from a battery, would be one that uses the same battery that Tesla now uses.The previous electronic handwarmers we tested were only half the stated capacity, and you could not swap the cells out when they died. They required an hour of labour, new batteries, and specialized tools and equipment (such as a spot welder) just to bring them up to their stated capacity. This one does not have either of those deficiencies, and it gets 10C hotter, reaching 165F, possibly due to using modern technology such as diodes mounted on direct thermal path copper, and the same batteries as the Tesla MK3. This items includes 1 pc of a 5,000 MAh 21700 Li-Ion cell. How does it work? You turn it on, and place it into your pocket. For flashlight buffs, the LED is a Luminous SST40 binned at 5000K (use I use 5000K instead of 6500K because I don't like the CRI index value of the high wavelength's, and I'd go even lower if I could). This LED can take more current than previous LED's such as the XML-2 (over 8 amps). The thermal path on the MCPCB is DTP Copper. It uses a smooth reflector, although OP can be special ordered. The switch selects three modes: low/medium/high. These modes are useful for controlling the heat of the light. It does not select strobe, or SOS, features which I deem unnecessary for a device that is primarily intended to warm your pocket, or find your way in the dark. This item does not include a charger, and ships with insulator tape over the terminals of the battery which must be removed, and the battery charged prior to use (21700 Li-Ion rechargeable battery included).

Handwarmers S04E12: 2020's best electronic handwarmer
Instead of just stating that the above model is currently the best choice for an electronic device to warm your pockets, this demonstration examines and explains each factor that led to giving substance to our hypothesis that this is the best option available to you for heating your pockets with a battery powered electronic device.
Handwarmer/flashlight 6A version
This is an S12 host, and what is unique about it is, it can 'host' the same 21700 cells that Tesla uses, and has 3 LED's at the bottom of the reflector. This affords us the opportunity to use three LED's with impressive CRI (Color Rendition Index) values that I've always wanted to try: the Nichia 219C, and the Luminus SST20. We can take advantage of the increased current draw of 3 of them, which will result in more heat. In fact the current draw of this unit which uses a high current driver, can reach 6 amps (think of having a 25W heater in your pocket)! And while this driver is supposed to have built in temperature protection management, we did not see that in the last video, nor is it apparent here as evidenced by achievable temps in excess of 90C. Wavelength is 4000K, and CRI value of approx 95. Includes a 5A 21700 rechargeable Li-Ion battery. Battery charger not included. Beam pattern is Flood. Temperature can be adjusted by changing the light intensity settings (4 modes: moonlight, Low, Med, High).

Handwarmers S04E14 Coronavirus safety and new technology for electronic handwarmers.
Before I get started on the discussion of this new model, a word about what's on everyone's minds these days, the spillover event related to the Coronavirus and Covid-19 (COVID-19 is the illness caused by the novel coronavirus). COVID-19 can also live on surfaces up to a few days, so we are going to look at what you can do for handwarmer safety. I know most of you are self isolating, and working from home. (Of course, as a guy with no friends, I'm used to being at home all day talking to my goldfish 'Wheeler', who is a great listener.) You may be concerned about the safety of your handwarmer, and the possibility of it to host shedded viral progeny. We'll first explore the questions around that as they pertain to the various handwarmers, both liquid fuel such as the zippo, and the newer battery operated devices. This will give you some guidelines for keeping yourself, and others, protected as best as possible while you recreate outdoors.

Deodorizer 30ml
(treats 2-3l of Naptha, requires oversize shipment postage, best to order with other items that are >2cm) Note: Plastic is not suitable for long term storage of Terpenes. If you plan to store this over the 'off-season', transfer the bottle contents to a glass or metal vessel with the smallest air cavity possible. Also, if you have any cans of 'Computer Dust Off', give your storage container a small squirt before you close the lid, as this purges the oxygen which otherwise will oxidize the aromatic hydrocarbons in the terpenes over time.

Video: Winter Cycling, Using handwarmers and pogies on your bike.
First episode in our liquid fuel handwarmer series for the 2020 season. With the advent of bike racks on every corner, overpriced bike locks with GPS, Bluetooth, and WiFi, and studded tires, it's remarkable how many bikes are now on the road all winter. This is true of fat bikes, mountain bikes, city commuter bikes, and road bikes. And showing up on all these bikes are various styles of "bar mitts" (also commonly referred to as "Pogies"). They work great unto themselves, allowing the user to cycle comfortably with thin cycling gloves. They also lend themselves to being taken to the next level with the addition of either liquid fuel handwarmers, or, for eBike riders with a convenient USB outlet on their battery pack, USB heating pads.
Glove liners for Bar Mitts
Originally developed for neuropathy and rheumatoid arthritis, they provide mild compression to support your joints. They are very comfortable, and provide warmth and functionality when you extract your hands from the mitts when cycling or skiing. As seen in our video on Handlebar Mitts for winter cycling. Half-finger style, fleece fabric made from cotton and spandex.
