FAQ

Acerpure COZY HF1

What is the noise level (in decibels) when the fan operates at maximum speed?

There is no specific decibel rating in the specifications since this product is intended mainly for outdoor activities. However, internal testing using a decibel meter showed the noise level does not exceed 50 dB at full speed.

How many fan speed levels can users choose from?

Acerpure Cozy HF1 offers 100 adjustable fan speed levels.
For quick access, it provides preset shortcuts:

Press the fan button 1–5 times to instantly jump to level 20, 40, 60, 80, and 100.

Pressing it a sixth time will turn off the fan.

If the fan button is long-pressed while the unit is on, the speed becomes freely adjustable from level 1 to 100. This feature allows users to fine-tune the airflow with greater precision based on their needs.

How long can the fan operate on a full charge?

The working time is approximately 2 to 6 hours, depending on the speed. If the Cooling Mode is activated, the battery lasts around 1 to 3 hours.

What is the estimated battery lifespan?

Battery life depends on usage. Typically, a 3600 mAh lithium battery may last 1 year or more with normal use. Avoid overcharging or deep discharging to preserve battery life.

Can the battery be replaced when its performance declines?

Acerpure Cozy HF1 comes with a 1-year warranty covering service and spare parts. Replacement battery availability is currently under internal review.

What type of charger is compatible with the device?

The fan uses a USB Type-C port and is compatible with any standard charger head.

Does the product support fast charging? How long does it take to fully charge?

Fast charging is not supported. It charges at 5V 2A and takes approximately 3-4 hours to fully charge.

Is the fan safe for children or allowed in airplane cabins?

While there are no specific studies confirming safety for children, it can be safely used in airplane cabins. The lithium battery complies with TSA safety limits.

Does the device have an auto shut off or overheat protection feature?

No. This fan does not include an automatic shut-off or heat sensor as it does not contain any heating elements.
