Core Benefits
Benefit 1 — Patented 60-Second Centrifugal Extraction
A 1,000 RPM motor drives a sealed centrifugal chamber, agitating ground coffee and room-temperature water to achieve full extraction in 60 seconds. The extraction mechanism is protected under China Utility Model Patent No. ZL 2025 2 0937091.5. Adjustable by roast profile: 1–2 cycles for dark roasts, 2–3 for medium, 3–5 for light.
Benefit 2 — Naturally Low-Acidity, Full-Flavor Extraction
Cold-water centrifugal extraction preserves volatile aromatic compounds — chocolate, caramel, and red-fruit notes — while minimizing the bitter compounds and chlorogenic acids that contribute to acidity and stomach discomfort. The result is a clean, naturally sweet cup with a smooth finish.
Benefit 3 — Cordless Portability with All-Day Battery
Weighing only 260 g with a 205 mm footprint, the KS001 is designed for desk, travel, and outdoor use. A built-in lithium-ion cell delivers up to 10 extraction cycles per full charge (actual results vary by water volume, bean type, and extraction cycles). Universal Type-C charging supports pass-through operation with any 5V charger or power bank.
Benefit 4 — 500 ml Food-Grade Carafe with Calibrated Scale
The food-grade PC body is shock-proof, with a capacity of 500ml. It is equipped with clear 100–500ml scale lines to ensure a stable and consistent extraction ratio for each cup. The 300-mesh nylon filter effectively filters fine powder, resulting in clean output.
Benefit 5 — Independently Verified Food Safety
Cold brew coffee produced by the KS001 was tested by the Guangzhou Institute of Microbiology under GB 4789.2-2022. Aerobic bacterial count remained below 1 CFU/mL for up to 12 hours at both room temperature and 2–8°C refrigeration — confirming the extraction system produces microbiologically stable coffee. The device carries CE, FCC, and MSDS certifications.
How It Works
- Dose.Add ground coffee to the 300-mesh nylon filter (recommend a 1:10 to 1:13 coffee-to-water ratio — for example, 40 g coffee to 500 ml water; grind to fine-sugar consistency).
- Pre-Soak.Slowly pour cold water over the grounds to saturate evenly and release trapped air — this critical step ensures uniform extraction.
- Fill & Brew.Add water to your desired mark, attach the motor unit, and press once. The KS001 runs a 60-second extraction cycle and stops automatically.

Frequently Asked Questions
Q: How long does a full charge last?
A: Up to 10 extraction cycles under typical conditions. Actual performance varies by water volume, bean density, and number of repeated cycles per serving.
Q: Can I use a USB-C PD fast charger?
A: No. The KS001 requires a standard 5V USB-C charger. PD fast-charging adapters trigger the device’s over-current protection and will not charge the unit. Use a standard phone charger (5V) or a power bank.
Q: How much coffee should I use?
A: We recommend a 1:10 to 1:13 coffee-to-water ratio — for example, 40 g of ground coffee with 500 ml of water. Adjust to taste.
Q: Can I make hot coffee?
A: The KS001 is designed for cold extraction. The brewed coffee concentrate may be heated separately if desired.
Q: How do I clean it?
A: The carafe and filter rinse clean under tap water. The motor unit should be wiped with a damp cloth — do not submerge.
