A 48oz Removable Reservoir for Five-Plus Cups
Keurig fits the K-Classic with a large 48-ounce water reservoir, enough to brew five-plus cups before refilling, and it lifts off so you can fill it at the sink rather than pouring water in awkwardly while it's mounted. The water level sensor can trigger a little early, so the brewer asks for a top-up before the tank is truly empty and you may get about three servings between fills, though it is a minor quirk. There also appears to be an auto-off that switches the brewer off after two hours of inactivity, a small energy saver for busy mornings.
