4 USB QC3.0 QC2.0 Fast Charging Buck Converter 6V–32V to 5V High-Speed Mobile Charging Module with Overcurrent Protection by Electrica

The 4 USB QC3.0 QC2.0 Fast Charging Buck Converter by Electrica is a premium-grade, high-efficiency DC-DC step-down module designed specifically for users who demand reliable and high-speed charging performance. Whether you are building a DIY power distribution board, assembling a custom charging station, upgrading a solar power setup, or powering multiple devices in a workshop environment, this powerful module ensures stable output, heat-resistant operation, and long-term durability. With a wide DC input range of 6V to 32V, it easily connects with batteries, adapters, SMPS supplies, solar panels, or any DC power source—making it highly versatile for electronics enthusiasts, technicians, and field professionals.

The module features four (4) independent USB ports, each engineered with built-in fast charging protocols including QC3.0, QC2.0, AFC, FCP, SCP, and PE+. This means your devices automatically detect the required voltage and switch intelligently between 5V, 9V, or 12V, supported by safe current regulation. The highlight of this module is its high conversion efficiency, typically 95% under normal load, ensuring minimal heat loss even during heavy usage. This significantly enhances energy savings and increases component lifespan.

For maximum device protection, the module integrates advanced safety features such as overcurrent protection, short-circuit protection, over-temperature protection, and reverse polarity protection. These safety systems work continuously to prevent damage to connected devices—even in demanding environments such as automotive setups, UPS battery banks, or solar systems.

Each USB port can deliver up to 3A at 5V, with a combined power output dynamically managed to ensure stability across all ports. Its compact PCB footprint, premium copper traces, and solid-state components make installation easy and reliable, even in tight DIY enclosures or custom electrical panels. Unlike cheap, unstable chargers, Electrica’s module ensures consistent voltage output without fluctuations, flickering, or overheating.
