USB 5V to 2.1mm DC Barrel Plug Cable – 24AWG, 5ft

Reliable 5V DC Power from A USB Port

This USB 5V to 2.1mm DC barrel plug cable makes it easy to power 5V devices—like addressable LED strip controllers, routers, and switches—directly from a standard USB port. Built with 24AWG copper conductors and a thick, durable jacket, it supports up to 3.5A max for dependable power delivery.

High-Quality 24AWG Copper Construction

The heavy-duty 24AWG copper wire minimizes voltage drop while the robust insulation improves durability and flexibility for everyday and commercial use.

Important Power Note

Not all USB ports supply the same current. Actual available amperage depends on the USB port/revision and whether the port supports enhanced charging modes. Always verify your power source’s rating before drawing high current.

Theoretical USB Port Current (Standard Downstream Port)

USB Revision	Max Current (A)	Typical Notes
USB 1.0 / 1.1	0.5 A (after enumeration)	Default 0.1 A; devices may request up to 0.5 A
USB 2.0	0.5 A	Standard downstream port
USB 3.0 / 3.1 / 3.2	0.9 A	Standard downstream port (non-BC, non-PD)

Some hosts/chargers support higher currents (e.g., Battery Charging 1.2 at ~1.5 A, or USB-C/USB Power Delivery at even higher levels). Check your USB source specifications if your device needs more current.

Applications

• Powering addressable LED strip controllers
• Routers, switches, and other 5 V devices with 2.1 mm jacks
• DIY electronics and test benches
• Upgrading lightweight DC power leads
