Q: Does the portable air cooler need to be refilled with water?
A: Yes. As an evaporative cooler, the Siboly XZ13-050 (5000 m³/h model) requires water to operate. It uses water evaporation to cool air (85% efficiency), unlike refrigerant-based ACs. Without water, it functions only as a fan.

Q: How long does a full tank last?
A: Approximately 7–14 hours, depending on:

• Tank Capacity: 69 liters (large-capacity design)

• Usage Conditions:

• Fan Speed: Higher speeds (3-speed settings) increase water consumption

• Climate: Hot/dry environments accelerate evaporation

• Room Size: Larger spaces (20–30 m² effective area) require more cooling

• Typical Runtime:

• Low speed: Up to 14 hours

• Medium speed: ~10 hours

• High speed: 7–8 hours

Pro Tips:

1. Monitor Remotely: Use the included controller to check water levels

2. Efficiency Hack: Add ice packs to reduce refill frequency in extreme heat

3. Maintenance: Refill daily during peak summer; use clean water to prevent mineral buildup

Why It Matters:
With only 0.25 kW power consumption (10% of traditional AC costs), water refills are a small trade-off for energy-efficient cooling in garages, hotels, or households.

Key product specs supporting this:

• Water Capacity: 69L

• Airflow: 5000 m³/h

• Evaporation Efficiency: 85%

• Power: 0.25 kW

• 3-speed settings + remote control
