Here are some of our most popular questions that people ask us about HotSnapZ hand warmers and heat packs
It happens all the time,. HotSnapZ have a WOW effect when you first use them that will cause you to share their warmth, comfort and happiness to all your family, friends and coworkers. It's okay, it happens to all of us. Who doesn't want a bit more warmth, comfort and happiness in their lives?
Besides that, their reusability and instant heat are features you won't find in using disposable hand warmers.
The chemistry inside HotSnapZ is a safe and self-regulating reaction. The maximum internal temperature reaches 128-130F and typically 115-120F at the surface during normal use.
The temperatures that HotSnapZ operate at are considered to be non-burning when used as directed.
HotSnapZ reusable hand warmers and heating pads contain water, a small metal disc and sodium acetate, a safe food grade salt ingredient.
When first boiled the mixture inside the pouch is heated to completely dissolve the sodium acetate in the water. This makes the contents clear and liquid.
After cooling, the sodium acetate remains dissolved producing a solution that is supersaturated.
This means that the heat energy that was required to dissolve the sodium acetate into the water still remains in the system even though the temperature has dropped. Almost like a Heat Battery!
The clicking of a disk within the pad triggers the precipitation of the sodium acetate crystals. When the crystals precipitate, it releases the energy that was required to initially dissolve it and stored in the pouch.
The release of energy raises the temperature to a maximum temperature of 130F (54C). The process is theoretically repeatable indefinitely. HotSnapZ are a sodium acetate hand warmer.
Really simple... HotSnapZ® like a heat battery. Once the heat has been exhausted, simply drop your HotSnapZ™ hand warmer or heat pad in gently boiling water for 5-10 minutes depending on the size of the product.
The heat from the boiling water reverses the chemical reaction inside your HotSnapZ. The crystals will return the liquid form, storing heat inside the product for later use.
Once cooled to room temperature, HotSnapZ™ are ready to used again.
In theory, the number of times that a HotSnapZ can reused is indefinite. However, the consequences of real life usually take their toll on HotSnapZ at some point via wear-n-tear, being torn, stepped on, forgotten in the boiling pan or having one of your friends walk off with them. So, we expect the average user to get 100-300+ uses.
For long-term storage, it is important to reactivate your HotSnapZ and store them in the liquid state.

Yes. The contents of each HotSnapZ are Safe, Non-Toxic and Non-Hazardous. (Water and Sodium Acetate)
'Hot-Snaps'. We get a lot of people that will say "HotSnap-Zee" which is okay fine with us. We only capitlized the Z years ago so we wouldn't confuse it for HotSnaps with the "S".
First, it is very import to think of HotSnapZ as a reusable heat battery. After activating your HotSnapZ, heat performance is dependant on how this energy is managed during use.
Second, keep cold air away from the hand warmer and heat pad. For hunters, fishermen, hikers and campers we recommend that you keep your HotSnapZ stored on an inside pocket of your jacket or coat until they are ready to be used. You will find this greatly improves the performance and use of your HotSnapZ for outdoor activity.
See...if the HotSnapZ starts at a cold temperature, a good amount of the released heat energy is reabsorbed back into the product to first warms itself up before giving off heat to you. Just as much you like the warmth, HotSnapZ do too!
Third, keep the pack insulated if possible. Use an insulated pouch, muff, covers, etc. This will make a big difference by preventing heat energy being lost to the cold air.
Heat duration depends on: Size, how it is used, & how well the product is insulated during use. HotSnapZ® hand warmers and heating pads will typically stay warm for 30 minutes to 2 hours, and then gradually cools down.
Yes. HotSnapZ come with a limited lifetime warranty. For detailed information on our warranty visit here.
To ensure longevity of your HotSnapz™ hand warmers and heating pads it is recommended to reactivate them as soon as feasible and to store them in the liquid clear state for long term storage.
This will sometimes happen and only means that the boiling time needs to be extended. To fix.....simply boil until all signs of crystals are gone and leave them in for one to two minutes longer. Longer boiling times will not affect the product or performance.
Yes they can! We have many customers who use HotSnapZ for scuba diving and snorkeling. Unlike the disposable kind that are typically sold in sporting good stores HotSnapZ™ will continue to work, even in the water!
