Ruth's sister 5V 2A 2.5mm DC USB power cable 78cm

SKU CH-ZQWF-5XYKT

A 78 cm cable that powers 2.5 mm barrel devices from any USB source at 5 V and 2 A

  • Charges tablets from USB sources using 5V 2A output
  • 78cm length gives flexible placement near power outlets
  • 5mm x .7mm plug fits compatible device ports
  • Twisted-pair construction supports error-free data transfer
  • USB 1.0, 1.1 and 2.0 compatible for wide device support

Power cable for 2.5 mm devices

This 78 cm cable converts a USB port into a 2.5 mm by 0.7 mm DC plug rated for 5 V and 2 A. It targets owners of tablets or smart devices that use this specific barrel connector. The twisted-pair construction supports USB 1.0, 1.1 and 2.0 signalling without extra drivers.

Steady 2 A delivery under load

The copper-clad steel plug maintains consistent contact during extended charging sessions from a PC, laptop, wall charger or car charger. The 2.0 specification ceiling means current stays at or below 2 A, so the cable does not overheat when the device draws its maximum rated input for long periods.

Plug orientation is the only fit risk

Insert the 2.5 mm male barrel straight into the device port; the 0.7 mm inner diameter leaves no room for lateral force. The 78 cm length reaches most desk outlets without strain, but devices with recessed or angled jacks may not seat fully. No retail packaging is included.

Questions about this item

Does the 78cm cable get warm when left plugged in all day?

The cable carries 5V at 2A through copper-clad steel pins and twisted-pair wiring, so it stays cool under normal tablet charging loads.

What must I already own to use this 2.5 x 0.7mm plug?

You need a device with a matching 2.5mm outer and 0.7mm inner DC jack plus any USB 1.0, 1.1 or 2.0 port such as a laptop, wall charger or car charger.

Will this work with my older tablet that only has USB 1.1 ports?

Yes, the cable is compatible with USB 1.0, 1.1 and 2.0 so it will charge from legacy ports without issues.
