GCON 12V to 5V Micro USB Buck Converter 3A 15W 3 Pack

SKU CH-9DHV-9MCB7

Three buck converters step 12 V down to 5 V at up to 3 A with 96 percent efficiency and built-in protection

  • Converts 12V to 5V for USB devices
  • Up to 3A output current powers demanding gear
  • 96 percent conversion efficiency reduces heat waste
  • Built-in over-voltage, over-current and short-circuit protection
  • Waterproof epoxy housing suits vehicle and outdoor installs

12V to 5V Buck Converter 3-Pack

This pack contains three DC-DC step-down modules that accept an 8-20V input and deliver a regulated 5V output at up to 3A. Each unit is rated for 15W maximum output power and features a Micro USB connector for the load side. The epoxy-sealed housing provides waterproof protection for the internal circuitry.

Installers powering low-draw 5V gear from a 12V

The converters suit GPS units, dash cameras, two-way radios, car audio players and similar accessories that draw less than 15W. They are not suitable for devices requiring more than 15W or for certain Samsung phones that the supplier notes as incompatible. Buyers needing higher output current or a different output voltage should look elsewhere.

Micro USB output with integrated protection

The Micro USB port lets you plug in standard cables without soldering. An onboard management chip provides automatic over-voltage, over-current, over-temperature and short-circuit protection. The supplier states a conversion rate of up to 96 percent and a no-load current of 10mA.

Questions about this item

What input voltage source do I need to power this 12V to 5V buck converter?

The module accepts any DC source between 8V and 20V, so a 12V vehicle or wall supply works directly.

Will my existing Micro USB devices draw more than the converter can safely supply?

Each unit delivers up to 3A at 5V (15W maximum); as long as the connected device stays under 15W it will operate normally.

How can I verify the converter is operating efficiently after installation?

The integrated regulator achieves up to 96 percent conversion efficiency, so minimal heat and stable 5V output under load confirm correct operation.
