BUCIER

BUCIER 2PCS DC-DC Buck Module 6V-32V to QC3.0 USB Charger

SKU CH-9TVP-D92MD

Two DC-DC buck modules convert 6-32V input to USB fast charging at up to 24W with 90-97% efficiency

  • Weight0.009 kilograms
  • Package Contents2 * DC-DC Buck USB charging module
  • Input range 6V-32V suits solar or vehicle sources
  • Automatic 3-12V output adjustment enables fast charging
  • 90%-97% conversion efficiency reduces heat loss
  • Over-current, short-circuit and over-temperature protection built in
  • Two compact 34×17×9.5mm modules included

Power Range and Protocol Support

This BUCIER two-pack supplies DC-DC buck modules that accept 6V to 32V input and deliver up to 24W through a single USB-A port. Each board automatically negotiates 5V, 9V or 12V output using Qualcomm QC2.0, QC3.0, Huawei AFC, MTK PE and other listed fast-charge protocols.

Solar, Vehicle and DIY Builders

Hobbyists powering phones, dash cams or small USB loads from solar panels, car electrics or bench supplies will find the wide input range and 90-97% conversion efficiency practical. Projects that need USB-C Power Delivery, fixed voltages above 12V or more than 24W per module must look elsewhere.

24W Maximum Output Power

The headline specification is the 24W ceiling (5V/3.4A, 9V/2.5A, 12V/2A). If your load demands more current or a higher voltage than 12V, this module cannot supply it and a different converter is required.

Questions about this item

What fast-charging protocols does the BUCIER module support?

The module handles Qualcomm QC2.0 and QC3.0, MTK PE1.1 and PE2.0, Huawei AFC, Spreadtrum SFCP, Apple BC1.2, Samsung and iPhone proprietary agreements.

What is the maximum output power the converter can deliver?

Maximum output power is 24 W, available as 5 V at 3.4 A, 9 V at 2.5 A or 12 V at 2 A depending on the negotiated protocol.

How much heat does the board generate when running continuously at full load?

Conversion efficiency ranges from 90 % to 97 %, so waste heat stays low; the board also includes over-temperature protection that shuts it down if it gets too hot.
