Eight small green circuit boards with USB ports and soldered components

GCON

GCON 12V to 5V DC Buck Converter USB Adapter (8 Pieces)

SKU CH-3TWY-PHSWA

Eight 12V-to-5V buck modules supply up to 3A at 15W with 96% efficiency and built-in protection

  • Converts 12 V vehicle power to 5 V USB for charging devices
  • Delivers up to 3 A with 15 W maximum output for compatible gear
  • Achieves 96 % conversion efficiency to minimise energy loss
  • Built-in chip provides over-voltage, over-current, over-temperature and short-circuit protection
  • Eight-module pack suits GPS units, dash cams, radios and other 12 V accessories

12V to 5V Buck Converter Pack

This eight-piece set of DC buck converter modules steps a 12 V input down to a regulated 5 V USB output. Each unit delivers up to 3 A with a maximum power rating of 15 W. They are suited for installers and hobbyists powering GPS units, dash cameras, two-way radios or similar 5 V accessories from a 12 V vehicle or industrial supply.

96% Efficiency and Protection

The integrated switching regulator achieves a conversion rate of 96%, keeping heat low during normal operation. A built-in microcontroller provides automatic protection against over-voltage, over-current, over-temperature and short-circuit events. Quiescent draw is only 10 mA when no load is connected.

Compact USB Power for 12 V Systems

Each module presents a standard USB port for direct device connection, removing the need for separate 5 V regulators or bulky adapters. The 15 W ceiling means they cannot run higher-power phones or tablets that exceed this limit. They free up space in vehicle consoles or equipment cabinets by replacing larger AC inverters or dedicated chargers.

Questions about this item

How do I wire the module into a 12 V vehicle circuit and what mistake should I avoid?

Connect the input leads to a fused 12 V DC source, then plug your device into the USB port; the common error is exceeding the 15 W limit, which triggers the over-current protection.

What upkeep or replacement will these converters need over time?

No scheduled maintenance is required; if a unit fails due to prolonged over-temperature or short-circuit events, simply replace that module from the eight-piece pack.

What is the first limitation reached during continuous high-load use?

The 15 W output ceiling is hit first; sustained draws above that level activate the intelligent chip’s over-current and over-temperature safeguards.
