Using this Biolite CampStove Kettlepot & Coffee Kit is easy. First, if you're using the KettlePot to cook a meal or boil water, place it on the BioLite CampStove. The 1.5 - liter capacity allows you to cook a decent amount of food or boil enough water for your needs. It boils 1 liter of water in just 4.5 minutes, so you won't have to wait long. When it's time to pour, the secure silicone seal and cool - touch handles make the process safe and easy. For coffee lovers, use the included CoffeePress to make French - press style coffee. When you're done using the kit, you can store the CampStove and CoffeePress inside the KettlePot to save space in your backpack. As for maintenance, after each use, clean the KettlePot and CoffeePress with warm soapy water. Make sure to dry them thoroughly to prevent rust, especially since the KettlePot has a stainless - steel body. Remember, the CampStove is sold separately, so take good care of it too.
