HETAI Digital Technology Co.,Ltd USB 3.0 to 5.5x2.1mm Adjustable 5V-12V Cable

SKU CH-GBEB-N34PZ

A USB 3.0 cable that steps 5 V input up to an adjustable 5 V–12 V output through a 5.5 × 2.1 mm barrel plug, delivering up to 1.5 A and 18 W for routers, LED strips or other 12 V devices

  • Connector TypeMicro USB to USB A
  • Adjustable 5 V–12 V output from a USB 3.0 source
  • Powers 12 V routers or LED strips during outages
  • 5 A maximum current delivers up to 18 W
  • 100 cm cable gives flexible placement
  • Voltage changes in 0.2 V steps via button

Power delivery for 12 V devices

This cable converts a USB 3.0 port into an adjustable 5.5 × 2.1 mm DC output. It is built for users who need to run routers, LED strips or similar 12 V gear from a compatible power bank or charger. The inline controller steps the voltage up in 0.2 V increments and remembers the last setting.

Requires a USB 3.0 source with 12 V output

Adjustable voltage from 5 V to 12 V only activates when the host port supplies USB 3.0 12 V power. A standard 5 V USB 2.0 port locks the output at 5 V and prevents any voltage change. The input connector is a standard USB 2.0 male plug.

1.5 A maximum current and 18 W ceiling

The cable delivers up to 1.5 A at the chosen voltage, topping out at 18 W. That headroom covers most compact routers and light strips. Loads above 18 W or currents above 1.5 A will exceed the design limit and are not supported.

Questions about this item

What does the 18W maximum output mean for my router or LED strip?

The cable can deliver up to 18W, so it will run a 12V router or LED strip drawing 1.5A or less; devices needing more power will not work.

How does the USB 3.0 input requirement limit the voltage adjustment?

Adjustable 5V–12V output only works when the source is a USB 3.0 charger; a standard USB 2.0 port locks the output at 5V.

Will the 5.5×2.1mm plug fit my device and how long is the cable?

The plug has a 5.5mm outer diameter and 2.1mm inner pin with centre-positive polarity; the cable is approximately 100cm long.
