GCON

GCON 9-36V to 5.2V USB Buck Converter Gender Changer

SKU CH-5C59-G9WTJ

A 9 V to 36 V DC buck converter that steps voltage down to 5.2 V with a USB output and quick-charge identification chip, delivering up to 30 W at 6 A from 9–24 V input, 25 W at 5 A from 24–32 V.

  • Wide 9-36V input suits vehicle and industrial power sources
  • Synchronous rectification delivers high efficiency across the full voltage range
  • DC jack plus screw terminals simplify wiring to diverse equipment
  • USB port with quick-charge chip supports most smartphones
  • Output power scales from 30W at 9-24V down to 18W at 32-36V

Wide Input Voltage Range

This buck converter accepts DC input from 9V to 36V and steps it down to a stable 5.2V USB output. It is designed for users who need to power or charge 5V devices from higher-voltage sources such as vehicle systems, solar setups or industrial supplies. The module includes both a DC jack and terminal blocks for flexible wiring.

Replaces Fixed Voltage Adapters

Unlike single-voltage wall warts, this unit covers the whole 9V to 36V span in one module. The upgrade is worth it when your source voltage varies or when you need to consolidate multiple chargers into one adjustable solution. Output power scales with input: 30W at 9V to 24V, 25W at 24V to 32V, and 18W at 32V to 36V.

Sustained Load Behaviour

Synchronous rectification keeps efficiency high across the input range, reducing heat during continuous operation. At the top of the voltage range the converter limits output to 3.5A, so prolonged draws at 32V to 36V run cooler than short bursts at lower voltages. The quick-charge identification chip negotiates optimal current with connected phones throughout the session.

Questions about this item

What input voltage range and connector types does the GCON 9-36V to 5.2V USB Buck Converter accept for power?

It accepts DC 9 V to 36 V through a DC jack or screw terminals, with output power varying from 30 W at 9-24 V down to 18 W at 32-36 V.

How do you wire the converter, and what polarity mistake should be avoided?

Connect the source to the DC jack or terminals observing positive and negative markings, then plug the USB device; reversing the input polarity can damage the module.

When should the USB quick-charge chip or the whole converter be replaced?

Replace the unit if the USB port no longer negotiates fast charge, output voltage drifts outside 5.0-5.3 V, or the module overheats under normal load.
