Yes. The 20-inch fan already includes one 18.5V 5.2Ah battery pack inside the package.

At the moment, replacement battery packs are not sold separately.

However, the fan is compatible with select DeWalt-style 18.5V battery packs if an alternative power source is needed.

The fan uses a BLDC (Brushless DC) motor model BL521W-035 running at DC24V.

Compared with traditional brushed motors, a brushless motor offers several practical advantages:

• quieter operation
  
• longer motor lifespan
  
• lower internal friction
  
• reduced heat generation
  
• improved efficiency for battery-powered use
  
• more stable high-speed airflow

In cordless portable fans, battery efficiency matters just as much as airflow.

A BLDC motor helps:

• reduce unnecessary power loss
  
• improve runtime efficiency
  
• maintain consistent airflow output
  
• reduce vibration and noise
  

This makes the fan more suitable for:

• overnight camping
  
• garages
  
• workshops
  
• RV use
  
• emergency backup cooling
  

Brushless motors are commonly used in professional power tools for durability and efficiency, and those same advantages apply to cordless cooling equipment.

These two measurements describe different aspects of performance.

Wind speed measures how fast the air travels. Higher wind speed helps airflow travel farther.

This fan reaches:

• over 22.96 ft/s
  
• approximately 7 m/s on high speed
  

Airflow (CFM) stands for cubic feet per minute and measures total air volume moved. Higher CFM helps circulate air across larger spaces like garages, patios, workshops, or campsites.

Fan airflow levels:

• Speed 1: 1000 CFM
  
• Speed 2: 1500 CFM
  
• Speed 3: 1900 CFM
  
• Speed 4: 2400 CFM
  
• Speed 5: 2600 CFM
  
• Speed 6: 2900–4000 CFM

Battery runtime depends on fan speed.

Lower speeds consume significantly less power, while maximum airflow settings require more energy.

Approximate runtime with the included 5.2Ah battery:

• Low speed: over 36 hours
  
• High speed: approximately 3 hours
  

The fan uses a 50W rated power system optimized for balancing airflow and battery efficiency.

The included 18.5V 5.2Ah battery can fully charge in under 2 hours under standard charging conditions.

No. The battery system does not currently support reverse charging or USB power output.

The battery is dedicated to powering the fan only.

Most portable fans prioritize compact size over airflow.

This 20-inch cordless fan is designed to provide:

• stronger air circulation
  
• longer airflow distance
  
• better cooling coverage
  
• higher airflow volume
  

while still remaining portable and battery-powered.

It’s intended more as a portable air circulator than a small personal desk fan.

Ice may be smaller when the water level is low.

All buttons are temporarily disabled during defrosting and return to normal afterward.

The ice maker is equipped with a low-voltage protection system that automatically stops operation when the battery level is too low. In some cases, the battery indicator may still show remaining power.

If the control panel appears as shown in the image (with both the “Small” and “Large” indicators off), it means the battery needs to be recharged. Please recharge the battery pack before using the machine again.

The first ice-making cycle after powering on typically takes about 10 minutes (for both small and large ice sizes). After that, the cycle time is automatically adjusted based on the ambient temperature. Higher temperatures may result in longer ice-making times, while cooler environments can speed up the process.

The machine doesn't refrigerate ice. Keeping the lid closed can slow the melting of ice cubes or transfer ice to a fridge for storage. The melted water will flow back into the water reservoir and then be recirculated to start the ice-making process again.
