Accepts 6–32V input and provides adjustable 3–12V output (default 5V) across four independent USB ports, each capable of triggering fast-charge negotiation for compatible devices.\n\nThe module automatically negotiates the optimal charging voltage and current with connected devices, supporting a wide range of fast-charge protocols. With comprehensive protection circuitry and stable output, it's well suited for powering Raspberry Pi 4B, Jetson Nano, mobile phone charging stations, and solar-powered setups.\n\nKey Features\n\n\n4× Independent USB Outputs – Each channel negotiates fast-charge protocols independently\n\nWide Input Range – 6V to 32V DC input (input must be at least 2V above output)\n\nMultiple Fast-Charge Protocols – QC2.0/3.0, Huawei FCP/SCP, Samsung AFC, MTK PE1.1/PE2.0, Spreadtrum SFCP, Apple, DCP, and BC1.2\n\nComprehensive Protection – Input over/under-voltage, input over-current, output over-current, short-circuit, and over-temperature protection\n\nDual Purpose – Works as both a fast charger and a regulated power supply\n\n\nSpecifications\n\n\nInput Voltage – 6–32V DC\n\nOutput Voltage – 3–12V (adjustable via fast-charge protocol; default 5V)\n\nOutput Current – 0–3A per channel\n\nOutput Power – ≤24W (e.g. 5V @ 3.4A, 9V @ 2.5A, 12V @ 2A)\n\nUSB Outputs – 4× USB-A\n\n\nSupported Fast-Charge Protocols\n\nQualcomm QC2.0 and QC3.0\nHuawei FCP / SCP\nSamsung AFC\nMTK PE1.1 / PE2.0\nSpreadtrum SFCP\nApple, DCP, BC1.2\n\n\nIdeal For\n\nPowering Raspberry Pi 4B and Jetson Nano from 12V or 24V sources\nCar charging retrofits and 12V vehicle installations\nSolar charger builds\nMulti-device USB charging stations\n\n\nPackage Contents\n\n1× 4-Way Fast Charge Buck Module\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2636,"title":"Default Title","sku":"DF-DFR0852","price":13.17,"on_sale":false,"in_stock":true,"available_quantity":39,"option1":"Default Title"}]}
