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

Jargon buster
Plain-language definitions for the technical terms used above.
- Buck converter
- A power circuit that reduces a higher DC voltage to a lower DC voltage. It is useful when your supply voltage is too high for a module or microcontroller and you want less heat and better efficiency than a simple linear regulator.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- QC3.0
- Quick Charge 3.0 (QC3.0) is a Qualcomm fast-charging technology in which a compatible charger and device negotiate a higher voltage over USB so charging can happen faster. A QC3.0 label indicates the kind of charger or power source a device can take advantage of, or that it can itself supply, for faster charging.
