Three black USB-A to 4.0x1.7mm barrel cables coiled together

Werleo

Werleo 3-Pack USB 2.0 A Male to DC 4.0x1.7mm 5V Cable 1.0m Black

SKU CH-KPJA-BN3JF

Three cables convert a USB 2.0 Type-A port into a 4.0×1.7 mm centre-positive barrel plug delivering up to 2.5 A at 5 V for 1.0 m

  • ColorBlack
  • Power devices directly from any USB 2.0 port
  • Supports 4.0 mm barrel jacks with 1.7 mm center pin
  • Delivers 5 V DC at up to 2.5 A for compatible gear
  • 0 m cable gives flexible placement on desk or bench
  • Three cables in one pack for multiple devices or spares

Three-pack 5 V power cables

The set contains three identical cables, each 1.0 m long, with a black finish. A USB 2.0 Type-A male plug on one end connects to any standard USB port, while a 4.0 mm outer by 1.7 mm inner barrel jack with centre-positive polarity fits compatible devices. The cables supply up to 2.5 A at 5 V DC, drawing power directly from the host port.

Replaces bulky wall adapters

These cables remove the need for a separate mains charger when powering small electronics that use the specified barrel connector. They are useful for travel or tidy desk setups where a free USB port is available on a laptop, desktop or hub. The upgrade makes sense when the device’s power draw stays within the 2.5 A limit and the barrel dimensions match exactly.

Powers portable drives and peripherals

The 2.5 A ceiling comfortably runs most 2.5-inch external hard drives, USB hubs, routers and similar 5 V gear. Devices that require more current, a different barrel size or a higher voltage cannot be powered by these cables. Builders needing to supply multiple high-draw devices simultaneously should look for a powered hub instead.

Questions about this item

Will the 4.0 mm outer and 1.7 mm inner barrel fit my device's power jack?

The cable uses a 4.0 mm outer and 1.7 mm inner male coaxial plug with centre-positive polarity. Check your device's jack dimensions and polarity marking before connecting.

What is the correct way to plug the USB-A end into a computer or hub?

Insert the USB 2.0 Type-A male connector fully into a standard USB-A port until it seats firmly; the moulded strain relief should not be bent sharply during insertion.

How often should I replace the cables if used daily for a 5 V 2.5 A device?

Inspect the moulded connectors and cable jacket regularly; replace any cable that shows fraying, exposed wires, or intermittent power delivery.
