PRODUCT DETAILS
One compact box fan, more ways to use it.

The built-in 18650 lithium battery supports cordless use, with reference runtime of approximately 3 hours on high, 4.5 hours on medium and up to 8 hours on low.
1/4-20 Quick-Release Mount
A standard 1/4-20 threaded mount on the bottom supports compatible tripods, straps and selected mounting accessories, expanding the product beyond normal tabletop use.

FAQ
Answers procurement teams usually need before sampling.
What makes EF2002C different from a standard table fan?
EF2002C combines a foldable box-style body, rechargeable battery, 110° manual airflow adjustment and a 1/4-20 mounting point. This gives users more placement options than a conventional fixed-base desk fan.
Can the fan be mounted on a tripod?
Yes. The bottom includes a 1/4-20 quick-release threaded mount that can be used with compatible tripods and selected accessories. Confirm load stability and the final accessory specification before launch.
How long can the 4000mAh battery operate?
Reference runtime is approximately 3 hours on high, 4.5 hours on medium and 8 hours on low. Actual runtime can vary with battery condition, ambient temperature and the approved production configuration.
Why does the charging-time data need confirmation?
The supplied specification contains two different charging-time references. The primary data lists approximately 7.5 hours plus tolerance, while a separate engineering note lists approximately 2 hours ±0.5 hour. The final webpage should use the value from the approved production specification and test condition.
Does the fan include electrical protection?
Yes. The supplied design information includes battery and circuit-board overcharge / over-discharge protection plus motor stall protection.
Can you support OEM or private-label projects?
The product page is designed for B2B sourcing. Typical project items may include color, logo, packaging, manual and market-specific documentation, subject to engineering and commercial evaluation.
