1. The product adopts high-quality PLA environmentally friendly 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 to use 3. solution, integrated power supply + speed control, more convenient to use. 4. Stable performance, built-in PWM signal generation circuit and PD/QC fast charging trigger. 5. Small speed regulator has a big role, with more than 45W PD fast-charging head can output up to 36W (12V3A) with the standard QC fast-charging head can output 18W (121.5A) Parameter: Product name: PWM speed regulator (fast charging version) Support protocol: PD/QC fast charging protocol Output voltage: 12V PWM frequency: about 25KHz Output current: PD up to 3A, QC up to 1.5A Case material: PLA+ ( molding) Input port: USB TYPE-C female port Output port: PWM 4Pin Speed regulation range: PWM duty cycle 0-100% Caution: Only support PD / QC fast charging head or charging treasure as a power supply device with more than 45W PD fast charging head can output up to 36W (12V3A) with the standard QC fast charging head can output 18W (121V1.5A) fast-charging version of the PWM speed regulator does not come with a USB cable, you need to self-match; high-current on the USB cable quality requirements are higher, please choose a high-quality cable, it is recommended that you use standard PD / QC fast-charging head or charging treasure, we recommend using standard PD /QC fast-charging head or charging treasure (with 12V gear), cell phone manufacturers private fast-charging protocols may be part of the compatibility problem!
