Kovea Hand Warmer

To activate the device, you simply fill the reservoir with standard lighter fluid and use a lighter or match to heat the platinum catalyst head for a few seconds. Once the catalyst begins to glow, the flameless heating process starts and will continue until the fuel is consumed.

Yes, the hand warmer is designed to be carried in a pocket, but it should always be used with the included fabric pouch. The pouch regulates airflow and prevents direct skin contact with the hot metal surface, ensuring you stay warm without the risk of burns.

When filled to its maximum capacity, the Kovea Hand Warmer provides a steady, consistent heat output for up to 12 hours. The duration can vary slightly depending on the ambient temperature and how much fuel you choose to add.

Because it uses a platinum catalyst for flameless combustion, it does not produce smoke. You may notice a very faint scent of lighter fluid during the initial ignition phase, but it should be odorless once the heating process is fully established.

It is difficult to turn off the device once the catalytic reaction has started. The most effective way to stop it is to remove the burner head to cut off the oxygen supply, but this should be done carefully with gloves or tools, as the unit will be very hot.
