How to use

Fill the cup with ingredients without exceeding the 300 ml capacity, attach the blending lid and secure the unit. Charge the battery via the included USB‑C cable until fully charged (approximately 3 hours). To start blending, press the power button twice (double-click) to unlock and then press once to run; the blending cycle typically finishes in about 40 seconds and the device will shut off automatically. For drinking, switch to the drinking lid, which preserves temperature during transport. Clean removable parts according to the user manual and avoid immersing the main motor unit in water.

Recommendations

Use fresh fruits and vegetables cut into small pieces for best blending results. Do not exceed the maximum capacity and allow the blender to rest between repeated uses to avoid motor overheating. Charge the device with the supplied USB‑C cable and follow the safety instructions in the manual.
