Unique-Bargains 1M DC Male 5.5x2.5mm to USB Male Power Extension Cord White

SKU CH-VZBF-B4G92

A 1 metre cable with a 5.5x2.5mm barrel plug on one end and a USB male connector on the other, letting you power USB devices from a barrel-output adapter

  • TypePower
  • 1 metre cable reaches distant power outlets
  • 5 mm by 2.5 mm barrel plug fits common DC jacks
  • USB-A male end powers USB devices from DC source
  • 5 mm wire diameter handles typical low-voltage current
  • Male-to-male design simplifies camera and device installation

Purpose and fit

This 1 metre cable converts a 5.5x2.5mm barrel power source into a standard USB-A male plug. It suits installers who need to run low-voltage cameras or sensors from an existing DC supply without adding a separate USB charger.

Behaviour under load

The 3.5mm outer-diameter wire carries 5 V power from the barrel jack to the USB connector for continuous operation. Voltage drop stays proportional to the one-metre length, so connected devices receive stable power during extended recording or monitoring sessions.

Upgrade context

It replaces improvised splices or bulky adapter bricks when a clean barrel-to-USB link is required. The step up is worthwhile whenever a tidy, fixed-length connection beats a loose multi-piece chain, but it does not add voltage regulation or data lines.

Questions about this item

Does the 5.5 x 2.5 mm barrel jack on this cord draw noticeable heat when powering a USB device all day?

The cord is a passive 1 metre link with a 3.5 mm outer diameter; it carries whatever current the attached supply provides and does not generate heat on its own.

Must I already own a power adapter with a 5.5 x 2.5 mm output to use this cable?

Yes, the cable converts a 5.5 x 2.5 mm barrel output to a USB-A male plug, so a matching barrel-output supply is required.

Will this cable work with an older 5.5 x 2.5 mm barrel power supply I have kept?

If the older supply has a 5.5 x 2.5 mm male tip and delivers a USB-compatible voltage, the cord will pass that power to the USB device.
