Two black USB-to-barrel cables coiled side by side

USB to DC 5.5x2.1mm Power Cord 5V3A 10FT 2Pcs

SKU CH-J8PP-817AV

A 10‑foot USB‑to‑DC 5.5×2.1 mm cable delivers 5 V at up to 3 A for cameras, routers and other 5 V gear

  • Stable 5V power delivery with pure copper core supporting 3A continuous output
  • Thickened 3.5mm cable with multi-strand copper and PVC jacket resists bending and pulling
  • 3M extra-long length enables flexible wiring for security cameras and LED installations
  • Wide compatibility with 5.5x2.1mm devices including routers, set-top boxes and low-power IoT gadgets
  • Direct-through design provides 5V input to 5V output with no voltage conversion for safe operation

Power Delivery Specifications

This USB-to-DC cord delivers a direct 5V pass-through with a maximum continuous output of 3A, yielding up to 15W. The pure copper core limits voltage drop to 0.2V at full load across the 3-metre length. No step-up or step-down conversion is performed, so the source must already supply 5V.

Intended Use Cases

The 5.5mm by 2.1mm barrel connector suits security cameras, LED lighting, routers and set-top boxes that accept 5V input. Devices requiring a different voltage, a higher current ceiling, or a non-barrel DC jack cannot use this cable. Buyers needing voltage conversion or longer runs without added drop should look elsewhere.

Decisive Compatibility Check

The barrel jack must measure 5.5mm outer diameter and 2.1mm inner diameter; any other pin size will not connect. Confirm the target device operates on 5V DC and draws no more than 3A before purchasing.

Questions about this item

What size DC barrel jack does the 5.5x2.1mm connector fit?

The connector fits devices with a 5.5mm outer diameter and 2.1mm inner pin, often marked as 5521 on the equipment label.

How do I connect the USB end to supply stable 5V at up to 3A?

Plug the USB-A plug into a 5V source rated for at least 3A; the cable has no step-up or step-down circuitry, so the source must already provide 5V.

When should I replace the 3m cable to avoid voltage drop?

Replace it if devices restart under load or a multimeter shows more than 0.2V drop at 3A across the 3m length.
