2-way Fast Charge Buck Module (Compatible with Raspberry Pi 4B & Jetson Nano)

2‑Way USB Fast Charge Buck Module is a compact DC‑DC step‑down power module designed for high‑efficiency mobile device charging and embedded power systems. Featuring integrated 5V charging recognition circuitry, this dual‑port fast‑charging converter works with approximately 99% of smartphones and USB‑powered electronics. A wide 6–32V input range allows flexible integration with automotive power, battery packs, and solar systems, while automatic fast‑charge protocol negotiation enables higher current delivery and shorter charging time compared with standard USB power modules. Independent dual USB outputs allow simultaneous charging or power supply tasks, making this buck converter suitable for portable electronics projects and custom power solutions.

Wide Input Range with Adaptive Output Voltage

A high‑efficiency step‑down power architecture supports a 6V–32V input range, enabling integration with vehicle electrical systems, battery packs, and renewable energy sources. Output voltage automatically adjusts between 3V and 12V according to negotiated fast‑charging protocols, with a default 5V output configuration. This adaptive voltage capability allows the power conversion board to deliver optimized charging performance for different devices while maintaining efficient energy conversion and stable electrical characteristics.

Dual Independent USB Fast‑Charging Channels

Two USB output ports operate independently, enabling simultaneous charging of multiple devices or parallel power distribution within embedded systems. Integrated fast‑charge recognition circuitry activates peak current levels supported by connected devices, reducing charging time compared with conventional USB power modules lacking protocol negotiation. Multi‑protocol compatibility allows reliable charging performance across a wide range of smartphones, tablets, and portable electronics.

Reliable Power Conversion with Integrated Protection

Stable voltage regulation ensures consistent output during long‑duration operation, making this DC‑DC fast‑charging board suitable for continuous power applications. Built‑in protection mechanisms include input over‑voltage protection, input under‑voltage protection, input over‑current protection, output short‑circuit protection, output over‑current protection, and system‑level thermal protection. These safeguards enhance operational safety in automotive charging retrofits, solar charging systems, and custom DIY power supply designs.

This compact dual‑USB fast‑charging power module fits a wide range of applications including mobile phone fast charging stations, car charger retrofits, solar charging systems, portable DIY power supplies, and embedded electronics projects requiring reliable high‑current USB output.
