Review: Useful length power cable - Straightforward power cable to meet specific need
Review: Works Perfectly - Works perfectly. I got this cable to power my the network switch in my room, the switch was being powered by a USB to DC plug but I am running out of plugs so decided to get this cable and just plug the USB into a spare port in the back of my computer. Since then it has worked great, I even took the switch and this cable to a LAN party and used my console to power the switch saving a plug and saved me putting an transformer in my bag. Only point I make is make sure that you are getting the correct barrel DC connector before buying type M and N are almost identical.

### ⭐⭐⭐⭐ May not be the correct cable for "compatible" equipment.
*by O***E on 1 November 2025*

Star Tech state that this cable is compatible with the exact model of my Star Tech device. However, the barrel connector turned out to be the wrong size. The cable itself is well constructed. Some voltage drop is to be expected when operating a 2m cable at 2 amps.
