Zippo hand warmers are rugged and reusable pocket-sized heaters that provide safe, gentle warmth through the combustion of Zippo fluid (light petroleum distillate). The amount of fuel required depends on the duration of warmth desired. The 12-hour hand warmer requires the plastic cup to be filled to the upper line, while the 6-hour hand warmer requires filling to the lower line. The amount of fuel translates to roughly 1/3 of an ounce or 0.34 ounces for the 6-hour warmer and 0.7 ounces for the 12-hour warmer. Zippo offers a 4-ounce bottle of hand warmer fuel, which can provide six refills for the 12-hour hand warmer.

What You'll Learn

Zippo hand warmers use light petroleum distillate as fuel
It is important to note that Zippo hand warmers consume oxygen and produce carbon monoxide during operation. Therefore, adequate ventilation is necessary when using these hand warmers. Additionally, the hand warmer should be placed in a protective fabric bag to prevent burns, as the metal surface can get very hot.
The amount of fuel required for Zippo hand warmers depends on the desired duration of warmth. Filling the hand warmer halfway will provide approximately 6 hours of heat, while filling it completely will provide 12 hours of warmth. The fuel volume for a 6-hour fill is around 0.34 ounces, and for a 12-hour fill, it is 0.7 ounces.
Zippo hand warmer fuel is available in 4-ounce bottles, ensuring multiple refills for extended use. The fuel is designed specifically for Zippo Refillable Hand Warmers, and it is important to follow the filling instructions carefully for optimal performance and safety.
Overall, Zippo hand warmers offer a convenient and effective way to stay warm during cold weather, utilizing light petroleum distillate as fuel to generate safe and gentle warmth.

They provide warmth for 6-12 hours
Zippo hand warmers are a great way to keep your hands warm for extended periods. The amount of warmth they provide depends on how much fuel you put in them. The small plastic filling cup that comes with the hand warmer has two markings: one for a half fill and one for a full fill. Filling the cup to the lower line will provide warmth for up to 6 hours, while filling it to the upper line will provide warmth for up to 12 hours. The amount of warmth may vary slightly depending on various factors, but you can expect it to last anywhere from 5 and a half hours to 12 hours.
The Zippo hand warmer works by combustion, igniting Zippo fluid (light petroleum distillate) to create a catalytic heater. This process breaks down molecules to generate heat. As the hand warmer burns fuel, it consumes oxygen and produces carbon monoxide. Therefore, it is important to always use the provided bag, as it regulates the amount of oxygen and, consequently, the temperature of the hand warmer. Without the bag, the hand warmer can get too hot and pose a safety risk.
To fill your Zippo hand warmer, first, remove the catalytic burner unit cover and pour the fuel into the cotton-like material at the top of the unit while keeping it upright. Ensure you do not mash down the material. Once you've filled it to your desired level, carefully wipe off any excess fuel and allow it to evaporate before igniting. Keep the hand warmer upright and let it rest for at least two minutes before lighting it to ensure the fuel is fully distributed.
Zippo recommends using their premium hand warmer fluid or lighter fluid to fill your hand warmer. A 4-ounce bottle of hand warmer fuel is available for purchase. With adequate ventilation, you can safely enjoy the warmth provided by the Zippo hand warmer for 6 to 12 hours.

The amount of fuel depends on how long you want the hand warmer to run
The amount of fuel you need for your Zippo hand warmer depends on how long you want it to run. The hand warmer will provide heat for 6 to 12 hours once turned on, depending on the amount of fuel you put in it. The small plastic filling cup has two markings—one for half full and one for full. Filling the cup to the lower line will provide around 6 hours of heat, while filling it to the upper line will provide 12 hours of heat.
The amount of fuel needed to fill the cup to the lower line is about 0.34 fluid ounces, and for the upper line, it is about 0.7 fluid ounces. This means that a 12-ounce flask of fuel will fill a 6-hour hand warmer up to 35 times or a 12-hour hand warmer up to 17 times.
If you only want to warm your hands, you can put about a third of an ounce of fuel into the hand warmer. However, it's important to remember that once the hand warmer is ignited, there is no safe way to stop the heating action. Therefore, it's recommended to place the hand warmer in its bag and on a fireproof surface if it is still warm.
The Zippo hand warmer relies on a catalyzed chemical reaction to break down molecules and create heat. This means that it consumes oxygen and creates carbon monoxide. Adequate ventilation is important to ensure safety.

The filling cup has two markings—one for 6 hours, and one for 12
The Zippo Hand Warmer is a refillable, pocket-sized heater that provides safe, gentle warmth through the combustion of Zippo fluid (light petroleum distillate). The Zippo Hand Warmer comes with a small plastic filling cup that has two markings—one for 6 hours, and one for 12 hours. The amount of fuel you need depends on how long you want the hand warmer to run. If you fill the cup to the lower line, it will provide heat for up to 6 hours. Filling the cup to the upper line will provide heat for up to 12 hours.
The filling cup helps to reduce spills, and should be filled with Zippo premium hand warmer fluid or lighter fluid. Once the cup is filled, the contents should be carefully and slowly poured into the filling hole on the hand warmer while maintaining the hand warmer in an upright position. It is important to remember to remove the burner before filling with lighter fluid. After filling, the burner should be replaced, and a flame applied to it. The hand warmer should then be placed in its warming pouch, and will provide heat for 6-12 hours.
The Zippo Hand Warmer is larger than expected, measuring roughly 4" tall x 2 3/4" wide. It is important to note that once ignited, there is no safe way to stop the heating action, and the hand warmer should be placed in its protective fabric bag and on a fireproof surface until the fuel is exhausted. The bag regulates the amount of oxygen and temperature of the hand warmer, and it should not be used without the bag as it may get too hot and cause injury or fire.
The Zippo Hand Warmer is a great option for those looking for a reusable and consistent heat source for outdoor activities.

The hand warmer should be upright when filling and igniting
When filling a Zippo hand warmer, it is important to keep it upright. This is because, when the hand warmer is upright, you can easily pour the contents of the filling cup into the filling hole without spilling. It is also important to keep the hand warmer upright after filling and before ignition. If the hand warmer is laid down, liquid fuel can get into the catalytic burner, which may cause a flame to occur upon ignition.
The hand warmer should be placed in the supplied protective fabric bag to prevent overheating. The bag regulates the amount of oxygen and, in doing so, regulates the temperature of the hand warmer. Without the bag, the hand warmer may get too hot and could cause injury or fire.
The Zippo hand warmer should be filled with Zippo premium hand warmer fluid. The small plastic filling cup has two markings: one for 1/2 full and one for full. Filling the cup to the lower line will provide around 6 hours of heat, while filling it to the upper line will provide 12 hours of heat. It is important not to overfill the cup, as this can cause a malfunction, risk of injury, and fire.
Once the hand warmer is filled, the catalytic burner unit should be replaced, ensuring it is fully seated. Any excess fuel should be wiped off, and the hand warmer should be allowed to rest in the upright position for at least two minutes before igniting. This allows the fuel to be fully distributed in the absorbent material and become available to the catalytic burner.
