In a well-insulated, covered container—a cooler, say—Joule can heat up to 10 gallons (40 liters) of water. In a covered pot, it can heat about 5 gallons (20 liters). When you’re cooking without a cover, we generally recommend limiting water volume to about 2.5 gallons (10 liters).
However, you can always use the clip to attach Joule to the rim of your container and increase the maximum water level, as demonstrated in the photo below.
