Setup
Before first use, fully charge the machine and clean all removable parts.
- Initial Charge: Connect the machine to a 5V/2A or 5V/3A USB-C power adapter using the provided Type C cable. The LED indicators will show charging progress. A full charge takes approximately 3-3.5 hours.
- Cleaning: Disassemble the filter basket and locking chamber. Wash these parts with warm water and mild soap. Rinse thoroughly and allow to air dry completely. Do not immerse the main body in water.
- First Cycle (Cleaning): Before brewing coffee, perform a cleaning cycle. Fill the water tank with clean water (without coffee grounds). Press and hold the power button until it beeps to start heating. Once heated, double-press the button to run the extraction cycle. This flushes the internal system.

Operating Instructions
Preparing Coffee Grounds
- Grind Coffee: For optimal results, use freshly ground coffee beans. The grind size should be fine, similar to table salt or slightly finer, suitable for espresso.
- Fill Filter Basket: Unscrew the locking chamber and remove the filter basket. Place the funnel on top of the filter basket. Use the spoon to add up to 20g of ground coffee into the filter basket.
- Distribute and Tamp: Use the distribution needle to evenly distribute the coffee grounds in the basket. Then, use the tamper to press the coffee grounds firmly and evenly. Ensure the surface is level.
- Assemble: Place the water diversion filter on top of the tamped coffee grounds. Screw the locking chamber with the filled filter basket back onto the main body of the machine. Ensure it is securely tightened to prevent leaks.

Brewing Espresso
- Add Water: Unscrew the top cap of the machine. Pour up to 70ml of cold water into the stainless steel water tank. For faster brewing and to conserve battery, you can use pre-heated hot water. Securely replace the top cap.
- Check Battery/Start Heating:
- Press the power button once to check the battery level (4 LEDs indicate 25% increments).
- Press and hold the power button until you hear a beep to start the self-heating process. The LED indicators will show the water temperature (e.g., 1 LED for 40°C, 4 LEDs for 92-96°C). Heating 70ml of cold water takes approximately 4-5 minutes. The machine will beep when the target temperature is reached.
- Start Extraction: Once the water is heated (or if using pre-heated water, skip heating and proceed), double-press the power button to begin the extraction. The machine will pre-infuse for a few seconds, pause for 10 seconds, then complete the extraction. The entire brewing process takes about 30 seconds.
- Stop Extraction: You can stop the extraction at any time by pressing the power button once. The machine will automatically stop once all water has been extracted or the maximum time is reached.
- Enjoy: Position your cup directly under the machine's outlet during extraction. Enjoy your freshly brewed espresso.

Maintenance
Regular cleaning and maintenance ensure the longevity and optimal performance of your espresso machine.
- After Each Use:
- Unscrew the locking chamber and remove the filter basket. Discard used coffee grounds.
- Rinse the filter basket, water diversion filter, and locking chamber under running water. Use the provided brush to remove any stubborn coffee residues.
- Perform a quick rinse cycle: Fill the water tank with clean water and run an extraction cycle without coffee grounds to flush the internal system.
- Wipe the exterior of the main body with a damp cloth. Do not use abrasive cleaners.
- Ensure all parts are dry before reassembling or storing.
- Descaling: Depending on water hardness and frequency of use, descaling may be required every 3-6 months or after approximately 500 uses. Use a descaling solution specifically designed for coffee machines. Follow the descaling solution manufacturer's instructions carefully.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Charge the machine regularly, especially if it will not be used for an extended period.
