PRODUCT DETAILS
One compact form, two practical heights.
EF1902 is designed around space efficiency and flexible placement. It can sit low as a compact table fan, then extend into a standing fan when broader room coverage is needed—useful for distributors seeking a differentiated rechargeable fan rather than another fixed-form desktop model.
Foldable & Telescopic Structure
The body folds down to only 103mm high for compact storage, then extends to 920mm for floor-standing use. One SKU supports both table and stand-fan scenarios.
7200mAh Rechargeable Battery
The built-in 3.7V 7200mAh battery supports portable use without keeping the fan connected to a wall outlet, helping buyers build a more flexible rechargeable fan program.
3-Speed Airflow Control
Three clearly defined levels—Low, Medium and High—cover a measured airflow range of approximately 3.1–4.0m/s, with fan speeds from 1350 to 1750r/min.
Flexible Air Direction
The fan supports horizontal oscillation up to 35° and manual vertical adjustment up to 180°, helping direct airflow in bedrooms, offices, living spaces and temporary setups.
Timer + Two-Level LED Ring
A 1 / 2 / 4-hour timer supports scheduled use, while the integrated two-level LED light ring adds practical ambient lighting without requiring a separate lamp.
Multi-Layer Protection
The battery and circuit board include overcharge and over-discharge protection, while the motor includes stall protection to support safer day-to-day operation.
