Description

Overview

A cable lead from a USB 2.0 Type-A male plug to a DC barrel plug, carrying 5 V off a port or charger into a barrel jack. The DC end is listed in five barrel sizes.

Specifications

  • Source end: USB 2.0 Type-A, male
  • Load end: DC barrel plug
  • Voltage: 5 V
  • Barrel sizes: 2.5 x 0.7, 3.5 x 1.35, 4.0 x 1.7, 5.5 x 2.1, 5.5 x 2.5 mm
  • Format: one-piece cable lead

Purpose

Small devices often arrive with a barrel jack and no supply, or the wall adapter goes missing. This puts the 5 V a USB port already gives onto the barrel; five sizes exist because the jack on the device decides the fit.

Applications

  • Small USB speaker or amplifier
  • Router or switch running on 5 V
  • Desk fan, LED lamp or diffuser
  • Replacing a lost 5 V adapter
  • Bench test from a power bank

How to Use

  1. Measure the jack bore and centre pin, then pick that barrel.
  2. Read the label: the device must ask for 5 V, since higher-voltage gear will not run here.
  3. Confirm the polarity the device expects before the first connection.
  4. Plug into a 5 V charger or power bank, not a data port you need.
  5. Check the charger’s current rating covers the draw before leaving it unattended.
