DC-to-USB fast-charge adapter

The WRIARICH step-down module converts a 10.5-32V DC barrel input into a 45W USB-C Power Delivery or USB-A Quick Charge 3.0 output. It suits installers adding fast charging to vehicles, solar rigs or industrial gear that already supply 12V or 24V DC. Buyers needing mains AC input or simultaneous dual-port charging should look elsewhere.

Automatic voltage selection and cable compensation

The IP6518 controller negotiates 3-20V output steps with the connected device and applies cable resistance compensation to maintain voltage at the far end. Supported protocols include PD, QC 2.0, QC 3.0, BC 1.2, SFCP, FCP, SCP and MTK PE+ 1.1/2.0. Conversion efficiency reaches up to 97 percent.

Verify input headroom and single-port use

Confirm your DC source stays at least 2V above the desired output voltage across the full load range. The 5.5x2.1mm jack requires centre-positive wiring. Only one USB port may be active at a time; do not connect devices to both ports simultaneously.

Questions about this item

Will the IP6518 control IC or the 5.5x2.1mm barrel jack need replacement after long use?

The IP6518 control IC and barrel jack are solid-state components rated for continuous operation; no scheduled replacement is required.

What thermal limit appears first when the adapter runs at 45W for hours?

Up to 97% conversion efficiency keeps dissipation low, so the 50x20x17mm enclosure temperature rises only modestly during sustained 45W output.

How much heat and fan noise does the 45W step-down produce when powering a laptop all day?

No fan is fitted; silent convection cooling handles the few watts lost at up to 97% efficiency, leaving the case warm to the touch but not hot.
