## Description

A 4-channel USB buck converter module with built-in fast-charge protocol support. 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. The 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. Key Features 4× Independent USB Outputs – Each channel negotiates fast-charge protocols independently Wide Input Range – 6V to 32V DC input (input must be at least 2V above output) Multiple Fast-Charge Protocols – QC2.0/3.0, Huawei FCP/SCP, Samsung AFC, MTK PE1.1/PE2.0, Spreadtrum SFCP, Apple, DCP, and BC1.2 Comprehensive Protection – Input over/under-voltage, input over-current, output over-current, short-circuit, and over-temperature protection Dual Purpose – Works as both a fast charger and a regulated power supply Specifications Input Voltage – 6–32V DC Output Voltage – 3–12V (adjustable via fast-charge protocol; default 5V) Output Current – 0–3A per channel Output Power – ≤24W (e.g. 5V @ 3.4A, 9V @ 2.5A, 12V @ 2A) USB Outputs – 4× USB-A Supported Fast-Charge Protocols Qualcomm QC2.0 and QC3.0 Huawei FCP / SCP Samsung AFC MTK PE1.1 / PE2.0 Spreadtrum SFCP Apple, DCP, BC1.2 Ideal For Powering Raspberry Pi 4B and Jetson Nano from 12V or 24V sources Car charging retrofits and 12V vehicle installations Solar charger builds Multi-device USB charging stations Package Contents 1× 4-Way Fast Charge Buck Module
