3.7V to 5V 7V 9V 12V Boost Board 4 Gear Adjustment Fan Motor Speed Controller USB Recharge Fan Circuit Governor Step Up Module Features: 1. Compact Design: The control board features a miniaturized design, making it suitable for installation in devices with limited space. 2. Boost Conversion Function: Built-in boost circuit can step up lower battery voltages (such as 3.7V lithium batteries) to meet the operating requirements of the fan motor. 3. Low Standby Current: In standby mode, the control board consumes extremely low current (e.g., 10uA), helping to extend the device's battery life. 4. Multiple Voltage Output Support: This boost board can step up the battery voltage to various output voltages such as 5V, 7V, 9V, and 12V. 5. Wide Range of Applications: This type of control board is widely used in small handheld fans powered by lithium batteries, suitable for the design requirements of portable devices.

Product Parameters: Product Name: Boost Board 9V Charging Fan Control Board Gear Positions: 1st gear 5V (red light on), 2nd gear 7V (green light on), 3rd gear 9V (blue light on) Input: Type-C 5V Output: Voltage - 1st gear 5V; 2nd gear 7V; 3rd gear 9V; 4th gear off (cycle), current should not exceed 0.6A Button Height: 6mm Hole Diameter: Approximately 2.5mm Product Size: 35.6mm*27mm Battery Terminal: With PH2.0 female connector, connects to 4.2V ternary lithium battery or polymer lithium battery, such as 18650 lithium battery. The battery terminal has reverse connection protection (wiring included; if using this wire to connect to the fan, you need to swap the red and black wires). Connects to a 3.7V lithium battery, charging power 5W, supports charging and discharging simultaneously. If not used with a battery, it can only operate at the lowest gear. Fan End: Equipped with a PH2.0 female connector, compatible with 5-8 inch brushless motors. Third gear provides 9V 600mA output. The fan end has reverse connection protection.

Product Name: 12V Charging Fan Control Board Gear Settings: 1st gear 5V, 2nd gear 7V, 3rd gear 9V, 4th gear 12V Input: 5V 1A, simultaneous charging and discharging requires using a 5V 3A or higher power supply. Charging Port: Type-C interface, supports 1000mA charging. Red light indicates charging, green light indicates fully charged and automatic shut-off. Supports simultaneous charging and discharging. Battery End: Equipped with a PH2.0 female connector, connects to 3.7/4.2V lithium battery. The battery end has reverse connection protection (forcibly charging with reverse battery connection will cause damage). Fan End: Equipped with a PH2.0 female connector, compatible with 5-8 inch brushless motors. Four gears with 12V 800mA output. The fan end has reverse connection protection (if the motor does not have reverse connection protection, the motor will be damaged). Package List: Control board *1 Cable *1 label:yes
