Two small black rectangular DC to USB converter modules each with two USB-A ports side by side

GCON

GCON 2-Pack 12V to 5V USB Adapter Dual USB 3A 15W

SKU CH-F0SD-8PDC4

Two 12 V to 5 V buck converters with dual USB sockets deliver up to 15 W at 96 % efficiency and include overcurrent, overvoltage, overtemperature and short-circuit protection

  • Converts 12 V to 5 V for USB devices
  • Up to 96 % conversion efficiency reduces heat
  • Dual USB ports charge two devices simultaneously
  • Built-in overcurrent, overvoltage and short-circuit protection
  • 15 W maximum output supports GPS, dash cams and audio

Compact 12 V to 5 V buck converter

This two-pack supplies dual USB-A ports from any 8-20 V DC source, delivering up to 3 A and 15 W total. It targets installers who need reliable 5 V power for dash cams, GPS units, two-way radios or similar accessories in vehicles, buses or fixed 12 V systems.

High-efficiency module with full protection

A switching regulator achieves up to 96 % conversion efficiency while over-current, over-voltage, over-temperature and short-circuit safeguards protect connected gear. The rugged potted construction resists vibration, and the flying-lead input plus dual female USB sockets allow quick, solder-free integration into existing wiring looms.

Replaces bulky cigarette-lighter adapters

Swapping a protruding 12 V plug for this inline module frees dashboard space and eliminates loose cables in permanent installs. The upgrade is worthwhile when the load stays below 15 W and the attached devices are not among the partially incompatible Samsung phones noted by the manufacturer.

Questions about this item

What input voltage range does the 12V to 5V adapter accept, and what output current does it cap at?

The adapter accepts an 8-20V input range and caps the total output at 3A across both USB ports, with a 15W power limit.

What physical mounting or wiring does the dual USB converter need for installation?

The module has a dual USB female socket and input leads for DC power; it requires a 12V or 20V source and panel space for the two ports.

How is the buck converter wired in, and which step do installers often miss?

Connect the input leads to an 8-20V DC supply observing polarity, then plug devices into the USB ports; the step often missed is confirming the load stays under 15W.
