Whether out camping in the wilderness or simply in a pinch for time, the Shangrao Hukang HK-JRB001 food warming pads are a quick and foolproof way to heat both food and beverages. The non-woven fabric inserts make use of chemical qualities in order to boil water in a matter of seconds, and each pad can further keep water at a boil for as long as 25 minutes at a time.
The Shangrao Hukang HK-JRB001 pads are filled with a proprietary combination of calcium oxide and various metal powders. Those chemicals naturally create a reaction with water that sets it to boil far quicker than even putting the water over a controlled flame. Best of all, since the chemicals are in a non-permeable fabric housing (reacting to moisture when it contacts the fabric rather than leaking into the water itself), the boiled water is completely safe and free of toxins.
