Capacities vary widely — from single‑serve or 1–2 cup machines up through mid‑size brewers and large urns that hold around 40 cups. Many models are available in several pot or serving sizes between these extremes.

Power draw depends on the type and model: smaller brewers commonly use about 850 watts, while higher‑power espresso and automatic machines can draw up to roughly 1,600 watts.

Many models use thermal carafes or hot‑holding urn designs to retain heat; some also include ready‑to‑serve indicator lights. Select thermal carafes are specified to keep coffee hot for 2+ hours, depending on model and ambient conditions.

Pump pressures vary by model and design. Several units report pump pressures around 15 bars, while at least one model specifies a 9‑bar extraction — so pressure can differ depending on the machine’s intended extraction profile.

Some automatic and semi‑automatic machines include built‑in grinders (often burr grinders) and are designed to grind, dose, and brew whole beans in a single workflow rather than relying on pods or separate grinders.
