OTC ZERO
Real espresso, anywhere.
The OTC ZERO is a portable espresso machine that fits in your bag. With a built-in battery, it handles everything from heating the water to brewing — all in one unit. Whether outdoors, at the office, or on the move, enjoy consistently high-quality coffee at the press of a button.
*Coffee capsules are not included.
Features
A full-fledged espresso machine in a portable size
Measuring φ69 mm × 224.5 mm and weighing approximately 763 g, its compact body slips neatly into a bag or backpack.
Built-in battery, 12V operation
The built-in battery powers everything from heating to brewing, so you can use it even where no outlet is available. (Charging requires a separately sold adapter.)
Simple one-button operation
Single click: Display battery level
Double click: Start brewing
Press and hold for 2 seconds: Start heating
Beeps and LED indicators keep you informed of the machine's status, making it intuitive to use even for first-timers.
Automatic heating to 92±3°C, plus cold brew support
The built-in heater automatically warms the water to approximately 92°C (a beep lets you know when it's ready).
In addition, brewing without heating when the water temperature is 50°C or below switches the machine to "Cold Brew Mode," slowly dripping a smooth, mellow iced coffee.
Ristretto, Espresso, Americano, and Latte
Adjust the water level to the "RIS" and "ESP" marks on the water tank to make a cup to suit any occasion:
Ristretto
Espresso
Americano (add hot or cold water afterward)
Latte (add milk)
Designed with safety in mind
Dry-boil detection: When the water tank is empty, the machine monitors the temperature rise; if an abnormality is detected, it alerts you with a beep and a red LED and shuts off automatically.
Pump blockage alarm: If no coffee comes out during brewing, the machine issues a warning and then stops automatically.
Heating timeout: If the set temperature is not reached, heating stops automatically after approximately 5 minutes 30 seconds.
Durable and splash-resistant for everyday use
The body is made from materials including PC, PA+GF, silicone, and SUS316 stainless steel.
With an IPX3 water-resistance rating (protection against everyday splashes), it's easy to handle in the kitchen or outdoors.
*Do not immerse the unit in water or wash it in a dishwasher.
