Ruth's sister USB QC3.0 to DC 5.5x2.5mm boost cable

SKU CH-7HDY-JW71C

Boosts a QC3.0 USB source to an adjustable 5 V–12 V DC output on a 5.5×2.5 mm plug, delivering up to 1.5 A for routers, LED strips and other 12 V devices under 18 W

  • Adjustable 5 V–12 V output from QC 3.0 USB
  • Powers 12 V routers and LED strips up to 18 W
  • 5 × 2.5 mm DC barrel fits common devices
  • Voltage steps in 0.2 V increments via button
  • Delivers up to 1.5 A from power bank or charger

Power for routers and LED strips

This USB QC 3.0 boost cable delivers adjustable DC output from 5 V to 12 V through a 5.5 x 2.5 mm barrel connector. It is designed for users who want to run a 12 V router, LED strip or similar low-power device from a QC 3.0 power bank or wall charger.

Inline voltage selector with memory

The cable body includes a push button that steps the output in 0.2 V increments across the 5 V to 12 V range. Once set to 12 V the cable remembers that level for the next use, and the 1.5 A current limit supports loads up to 18 W without external power bricks.

Replaces fixed-voltage wall adapters

The cable removes the need for a dedicated 12 V mains adapter when a QC 3.0 source is available, making it useful for backup router power during outages or portable LED lighting. It cannot supply adjustable voltage from a standard 5 V USB port, so a QC 3.0 charger or power bank is required.

Questions about this item

What does the QC 3.0 USB input cap the adjustable output at?

The cable steps up a QC 3.0 USB source to a DC 5.5×2.5 mm plug, adjustable from 5 V to 12 V at up to 1.5 A; a standard 5 V USB input locks the output to 5 V only.

What connector and clearance does the 5.5×2.5 mm DC plug need?

The output end is a 5.5 mm outer, 2.5 mm inner barrel jack, so the device must accept that exact coaxial size and have enough depth for the plug body.

How do I set the voltage using the button on the cable?

Each press changes the output by 0.2 V; press repeatedly to reach the desired level between 5 V and 12 V, and the cable remembers the last setting when powered from a QC 3.0 charger or power bank.
