Ruth's sister USB 5.5x2.1mm 1.3V-12V adjustable voltage power cable 130cm

SKU CH-9CSV-Y0SBQ

Adjustable 1.3V-12V DC cable powers LED strips, fans and toys from a USB port with real-time voltage display

  • Adjustable 1.3V-12V output powers diverse low-voltage devices
  • Real-time LED display shows exact voltage setting
  • USB 5V input draws from common power banks or chargers
  • 130cm cable length gives flexible placement options
  • On-off switch and potentiometer allow precise manual control

Purpose and fit

This USB to 5.5x2.1mm adjustable cable powers small devices such as clocks, toys, fans and LED strips from any standard 5V USB source. It suits hobbyists and repairers who need a variable supply between 1.3V and 12V without a bench unit.

Sustained behaviour

The integrated DC-DC module delivers up to 3W at 1.3V-5V and 6W at 6V-12V, with a 0.5A current limit across the range. A two-digit LED display shows the set voltage in real time while a rotary potentiometer adjusts it, and an on-off switch cuts power without unplugging.

Build and connections

The 130cm plastic-sheathed cable ends in a 5.5x2.1mm barrel jack that can be removed for direct wiring. The USB plug accepts 5V at 2A-3A from chargers or power banks, making the lead a portable replacement for 9V AA or AAA battery packs in LED lighting and fan projects.

Questions about this item

Does the 130cm cable get warm when it runs at 12V 0.5A all day?

The built-in DC-DC module steps the USB 5V input up or down, so the 5.5×2.1mm jack delivers 1.3V-12V at up to 0.5A; typical efficiency keeps the cable body only slightly warm during continuous use.

What USB power source do I already need to run this cable?

Any standard USB port or charger that can supply 5V at 2A-3A will power the adjustable module and the 5.5×2.1mm output.

Can I power a 3528 LED strip that used a 9V battery box with this cable?

Yes — set the potentiometer to 9V, the LED display confirms the output, and the 5.5×2.1mm jack replaces the battery box directly.
