Parameter: Shell material: ABS Input: 5V2A Maximum power: 5W Use: USB plug-in, data cable plug-in (shipping does not come with a free data cable) Output: 5-9V 1A Rated power: 3W Input jack: USB/Type-c Warm tips: row plug with USB port can also be used Package include: Speed controller *1 DC4-12V USBFeatures 1. Supports DC 4-12V input voltage to meet diverse application needs 2. Equipped with multi-speed adjustment module for flexible airflow control 3. Achieves low-noise operation for quiet and comfortable use 4. Compact mini design for easy portability 5. Low power consumption and high operational efficiency, energy-saving and eco-friendly for extended use Parameter Input Voltage: DC 4-12V Output Voltage: DC 2.5-7.5V Rated Power: 5W (Do not overload) Product Features: USB fan airflow adjustment with stepless speed control, freely adjustable from gentle to powerful breezes Speed Control Principle: Non-adjustable USB fans directly power the motor with 5V electricity. Two-speed fans incorporate an internal boost circuit board. When set to the second speed, this board elevates the USB's 5V voltage before connecting to the motor, increasing airflow. This stepless speed controller outputs a variable voltage range between 2.5V and 7.5V, allowing wide-range airflow customization. Turning the knob clockwise increases speed; counterclockwise decreases it. The knob also functions as a power switch. Note: 1. When adjusting the fan to two-speed mode, ensure the fan is set to single-speed mode first; otherwise, speed adjustment may fail. 2. Use within the specified voltage range. Package include Speed Controller*1 DC5V 4PIN Type-C AFeatures: 1. The product is made of high-quality PLA environmental shell material, good toughness and wear resistance, excellent electrical insulation 2.The input of the product is TYPE-C female port, can be perfectly compatible with TYPE-C port charger (PD) as a power supply device use 3. All-in-one solution, integrated power supply + speed control, more convenient to use. 4. Stable performance, built-in PWM signal generation circuit and DC-DC boost circuit. 5. Small speed regulator has a big role, compatible with most of the USB fan pump speed, can also be applied to routers / small host / soft routing and other DIY cooling Product Description: PWM speed regulator input for the C port, the output is a small 4Pin socket for PWM fan, built-in DC-DC boost circuit, 5V boost to 12V, speed regulation is achieved by outputting PWM signals, because the built-in boost circuit has losses (efficiency of roughly 85%), the output current is too large then there will be significant heating, it is recommended that the output current is controlled at 0.5A or less, for a short period of time can be up to 0.7A. Parameter: Product name: PWM speed regulator Input voltage: 5V Output voltage: 12V PWM frequency: about 25KHz Output Current: Rated 0.5A Upper limit 0.7A Case material: PLA+ (FDM molding) Input port: USB TYPE-C female port Output port: PWM 4Pin (KF2510) Speed control range: PWM duty cycle 0-100% Package include: Speed Controller *1 30cm short cable*1 DC5V 4PIN Type-C BFeatures: 1.The product adopts a 3d printed shell, which is tough, wear-resistant, and has excellent electrical insulation. 2.The input end of the product is a usb type-c female port, which can be compatible with type-c port chargers (pd) as power supply devices. 3.Integrated solution, integrating power supply and speed control knob, making it more convenient to use. 4.Stable performance, built-in pwm signal generation circuit and dc-dc boost circuit. 5.Supports 12v standard fan speed control, compatible with most usb fan and water pump speed regulation, and can also be used for diy cooling of routers/small hosts/soft routers, etc. Parameters:  Product name: pwm governor Input voltage: 5v Output voltage: 12v Output current: rated 0.5a, upper limit 0.7a Pwm frequency: approximately 25khz Power interface: usb type-c female port Fan interface: pwm 4pin*1 Speed range: pwm duty cycle 0-100% Product size: 45*22*18.5mm Package include: Speed controller*1 30cm power cord*1 label:yes
