- LCD displays input voltage, output voltage, temperature, current, power, capacity statistics, and time statistics.
- USB female output port enables easy connection to USB devices such as USB fan.
- Screw-free quick connection terminal, push-type wiring. Easy wiring, requiring no screws.
- Smart Quick Charge Function: It solves the problem of insufficient power supply caused by USB input port. Support for QC2.0 3.0, FCP SCP AFC and other mainstream fast charge protocols. Automatic quick charge mode can be set or not to set according to your needs.
- High power 15W & 2A current can be used for fan speed regulation, desktop power supply, adjustable charger, router power supply, etc.
- Adjust output voltage arbitrarily, limit the current 0-2A (Wide input 4-13V, wide output 1-30V adjustable, with short-circuit protection.)
- Can be used as a USB charging cable. Adjust charging voltage and maximum charging current arbitrarily (With constant current, anti-backflow, to meet your needs)
- Multiple Protections: Short-circuit, over-current, over-temperature, over-power, over-voltage protection, charging anti-backflow protections)

Applications:
- High and low power fan governor
- USB adjustable desktop small power supply
- USB adjustable charging cable
- Router backup power
- Mobile power base
- For DJI Mech Master Outdoor Battle Router Power Supply
- USB adjustable boost cable
- Use with charge banks as mobile adjustable power supply

Specifications:
- Input voltage: 4-13V (3 input interfaces: USB male port, MicroUSB, TYEPE-C)
- Output voltage: 1-30V (easy-wiring terminal output, USB female output. Attention: These two are directly connected, please carefully check the output voltage before plugging in your USB device)
- Output current: 0-2A (The output current in constant voltage mode is adaptive according to load size, which is not adjustable. If you set current limit to 1A, it will automatically enter constant current mode and output 1A maximum when load current is greater than 1A)
- Output power: less than 15W (When the output power is greater than 15W, the output is automatically turned off and OPP is displayed. After reducing load power, press ON / OFF button to solve the problem). When input current is too large, it may not be able to work for more than 10W for a long time due to temperature protection
- Voltage display: resolution 0.01V, default precision ± (0.5% + 3 digits). Factory calibration without customer's own calibration function
- Current display: resolution 0.001A, range 0-2A, default precision ± (0.5% + 3 digits). Factory calibration without customer's own calibration function
- Power display: 0.00W-15.0W
- Temperature protection: When power component's temperature is higher than 110℃, it will enter OTP protection. After reducing load power, press ON / OFF button to solve the problem. (For long-term work within 10W, it generally does not enter OT protection. When input current is greater than 3A, over-temperature protection may be entered during long-term work, even if it does not reach 15W. Recommended to use an adapter with fast charge function)
- Working current: about 30mA
- Charging anti-backflow: Yes
- Short-circuit protection: Yes

Package Included:
- 1 x Adjustable USB Power Supply Module  

Note:
- Electronic knowledge is highly recommended.
- It is powered by a 5V charging power adapter. With input over 4A, the module can output 15W. (considering the voltage drop on USB cable and the module conversion efficiency, etc.). It is difficult to realize with an ordinary 5V adapter. Therefore, the module adds a fast charge triggering function, which can make an adapter to output high voltage or high current. Fast charge function only supports chargers or charge banks with quick charge protocols.

Fast Charge Application:
1.Press and hold the SET / M button on thumbwheel for more than 3 seconds to automatically enter fast charge protocol selection interface. And LCD screen will display protocol name.

2. Short press the + and - buttons of thumbwheel to select QC2.0, QC3.0, AFC, FCP, SCP, AUTO, OFF. Short press SET / M button to trigger related protocol. If the trigger is successful, OK will be displayed, and the FC blue light is always on. Otherwise, Err is displayed, and the FC blue light is off. Or after selecting protocol, pressing SET / M button will trigger the function, and then directly exit the fast charge protocol interface, and the protocol will be triggered every time after power-on.

3. If you do not know which protocol your charger supports, you can select AUTO mode, and the module will automatically select a protocol to match. If you do not want to use this function, you can choose OFF mode.

Voltage & Current Settings:
Short press SET / M button, V blinks, set voltage by short pressing or long pressing +, - buttons. Press SET / M button again, A flashes, set current by short pressing or long pressing +, - buttons. Then press SET / M button once again to exit the setting interface. Or it will automatically exit the interface, without operation over 10s.

Short press + and - button so that voltage step is 0.01V, current step is 0.001A. Long press + and-button, the voltage step is 0.1V, and the current step is 0.01A.
