USB adjustable power module mobile boost line, stove fan speed control blower LCD display 15W DP3A

15W USB adjustable power module (with deception, LCD display, potentiometer adjustment version)
Application scenarios: high-power and low-power fan speed controllers, USB adjustable desktop small power supply, USB adjustable charging cable, router power-off backup power supply, Tmall Genie mobile power base (paired with power bank), USB adjustable boost cable, used in conjunction with power bank to instantly change various mobile power supplies, very practical.
Powered by a 5V charging adapter, the output of the module can only reach 15W with an input of 4A or more (considering USB line voltage drop and module conversion efficiency). It is difficult for a regular 5V adapter to achieve this, so the module has added a fast charging deception function, which can lure the adapter to output high voltage or high current. Please choose a charger or power bank that supports fast charging protocols in order for this product to successfully deceive you!!!
The use of fast charging scams:
1. Press and hold the TRIG button for more than 2 seconds and release it to enter the fast charging protocol selection interface. The LCD screen will display the protocol name.
2. Short press the TRIG key to select QC2.0, QC3.0, AFC, FCP, SCP, AUTO, or OFF. Short pressing the ON/OFF or SELECT button can trigger the protocol. If triggered successfully, it will display OK and the FC blue light will be on. Otherwise, it will display Err and the FC blue light will be off.
3. Press and hold the TRIG button for more than 2 seconds to exit the fast charging protocol interface. This protocol will be triggered every time the device is turned on in the future.
If you don't know which protocol the charger supports, you can choose AUTO mode, and the module will automatically select deception; If you don't want to use the deception function, you can choose the OFF mode.
1. Baby highlights:
1. LCD displays input voltage, output voltage, current, power, and capacity statistics, with a voltage resolution of 0.01V and a current resolution of 0.001A
2. With USB female output, it is convenient to connect USB interface devices such as USB fans
3. Screw free quick wiring terminal, press type wiring and unplugging, no need to tighten screws, convenient and fast.
When setting the current limit value (constant current), there is no need to short-circuit or use a multimeter, and the current limit value can be directly displayed
5. Equipped with intelligent fast charging to deceive and solve the problem of insufficient power supply to the USB input port. Supports mainstream fast charging protocols, QC2.0 3.0, FCP SCP AFC, and can also choose not to deceive or automatically select the deception mode.
6. High power 15W, 2A current, can be used for fan speed regulation, desktop power supply, adjustable charger, router power supply, etc.
7. Adjust the output voltage arbitrarily, limit the current to 0-2A (wide input 4-13V, wide output 1-30V can be adjusted arbitrarily, with short circuit protection, short circuit not burning)
8. As a USB charging cable, it can be used to adjust the charging voltage and maximum charging current at will (any voltage, with constant current, anti backflow, meeting the charging needs of most batteries)
9. Multiple protections (short circuit, overcurrent, over temperature, over power, overvoltage protection, charging anti backflow protection)
