PRODUCT DETAILS
One desktop footprint. Two everyday functions.
EF1903 combines a rechargeable table fan with a wireless charging area, helping importers and private-label buyers build a cleaner multi-function desk product instead of adding another single-purpose appliance.
10W Wireless Charging
The integrated charging area supports up to 10W wireless charging. When a 9V / 2.6A adapter is connected, the wireless charger enters fast-charge mode.
Battery or External Power
The wireless charging function can operate from the internal battery system or an external USB power source. Battery-powered charging runs in standard charging mode.
60° Touch Oscillation
A touch oscillation key controls the 5V stepper motor. Press once to start the 60° swing function and press again to stop it.
2 / 4 Hour Timer
The touch timer offers two simple settings—2 hours or 4 hours—and powers the product off automatically when the selected period ends.
Protected Rechargeable System
The battery and control board include overcharge and over-discharge protection to support stable rechargeable use across daily desk scenarios.
Motor Stall Protection
Motor stall protection adds another layer of operational protection, supporting a more complete safety story for OEM and distributor evaluation.
