Black USB to 5.5×2.1 mm DC cable with voltage button, 100 cm

Ruth's sister

Ruth's sister QC 3.0 USB to 5.5×2.1 mm DC adjustable cable 100 cm internal power cable

SKU CH-Z4AP-1RAYQ

Adjustable 5.5×2.1 mm DC cable converts QC 3.0 USB input to 5 V–12 V at up to 1.5 A and 18 W over 100 cm

  • Adjustable 5 V–12 V output from a QC 3.0 USB source
  • Button steps voltage in 0.2 V increments and remembers the last setting
  • Powers 12 V routers, LED strips and similar devices up to 18 W
  • Delivers up to 1.5 A from a compatible QC 3.0 charger or power bank
  • 100 cm black cable with 5.5 × 2.1 mm DC plug for internal routing

Power delivery for routers and LED strips

This cable converts a QC 3.0 USB source into a 5.5 × 2.1 mm DC output that can power routers, LED strips and similar 12 V devices. It is built for users who want to run networking gear or lighting from a QC 3.0 power bank or wall charger. The adjustable voltage lets you match the exact requirement of the connected equipment.

Limited to QC 3.0 sources and 18 W ceiling

The cable only negotiates higher voltages when the USB host supports QC 3.0 at 12 V; a standard 5 V USB port keeps the output fixed at 5 V. Maximum output current is 1.5 A and peak power is capped at 18 W, so devices drawing more cannot be used. Voltage steps change in 0.2 V increments via the onboard button.

Replaces fixed-voltage USB power adapters

It removes the need for a dedicated 12 V wall wart when a QC 3.0 charger or power bank is already available. The jump is worthwhile for portable router backup or mobile LED lighting where a single USB-C or USB-A QC 3.0 source replaces multiple fixed bricks. It does not suit devices that need more than 18 W or a non-QC USB supply.

Questions about this item

How do I pick the right output voltage for my device?

Press the button to step the output in 0.2 V increments from 5 V up to 12 V; the cable remembers the last setting so it starts at 12 V next time.

What does the 18 W maximum actually deliver to my router?

At 12 V the cable can supply up to 1.5 A, giving a ceiling of 18 W — enough for a typical 12 V router or LED strip under that limit.

Which USB chargers or power banks will let me use the adjustable 5 V–12 V range?

Only QC 3.0 USB chargers or power banks that provide a 12 V QC 3.0 profile; a standard 5 V USB port locks the output to 5 V.
