Which capsules does it work with?
It brews small Original-line size capsules (with the small-capsule adapter) and larger pod-style capsules (with the large-capsule holder). Check that your capsule matches one of these two sizes before ordering.
Can I use my own ground coffee?
Yes. Fill the included basket with fine, espresso-grind coffee, press the lid on, and brew. Coarser grinds give a weaker shot.
Does it heat the water itself?
Yes. Add cold or room-temperature water and double-click the button. The light flashes orange while it heats, then it brews automatically. Heating takes about 4–6 minutes depending on how cold the water is (manufacturer figure).
Can I use hot water to brew faster?
Yes. Add hot water and press and hold the button for 2 seconds. The light flashes green and extraction starts right away.
How many coffees per charge?
The manufacturer rates it at up to about 4 brews when heating cold water, or about 50 brews when you add water that is already hot. Real-world numbers vary with water temperature.
