SKU CH-BNGS-4RAP6

Triggers fixed-voltage output from QC-enabled USB chargers and power banks, supporting 2.0, 3.0 and 4.0 protocols

  • Product typeQC Trigger
  • Powers devices from affordable QC chargers and power banks
  • Negotiates QC 2.0 for fixed voltage output from USB sources
  • Forward compatible with QC 3.0 and QC 4.0 standards
  • Delivers 9 V, 12 V or 20 V depending on source capability
  • Voltage and current limits set by the connected power source

QC Trigger Module for USB Power Sources

This module negotiates fixed voltages from Quick Charge enabled chargers and power banks. It supports QC 2.0 with forward compatibility for QC 3.0 and 4.0 protocols. Makers and repair technicians use it to power projects from common USB supplies. It does not suit devices that require USB Power Delivery negotiation or voltages beyond the QC standard.

Selectable 9V 12V 20V Output Headroom

The adapter requests 9V, 12V or 20V from the source, but the actual voltage and current limit depend entirely on the connected charger. A power bank labelled for 9V only will not provide 12V or 20V regardless of module setting. The module passes through whatever the source agrees to supply without regulation or conversion.

No Cables or Configuration Software Included

The unit ships as a bare board with a USB Type-A input and solder pads for output. Users must provide their own wiring and verify the charger's supported voltage labels before use. There is no firmware to update and no desktop utility to install. Buyers needing a ready-to-use barrel jack cable or voltage display must source those separately.

Questions about this item

Will the JacobsParts USB Type-A QC 2.0 3.0 4.0 Trigger Module work with my existing QC 2.0 power bank?

Yes, it performs QC 2.0 negotiation and is forward compatible with QC 3.0 and 4.0, so it will request a fixed voltage from your QC 2.0 power bank.

How do I confirm the module is delivering the 9V, 12V, or 20V output I selected?

Measure the output terminals with a multimeter while the module is connected to a QC enabled charger; the voltage present matches the negotiated level.

Does the package include a USB charger or cables, or must I supply them?

Only the trigger module is included; you must provide a QC enabled USB Type-A charger or power bank and any cables needed for your device.
