What I needed!

Fair price, quick turn, and had the inventory in an obscure AC power supply for an older mechanized village ornament. AC-DC PowerShack had exactly what I needed. Thanks!

Simple and Reliable

The cable does exactly what it's supposed to do. The build quality is solid, the finish is clean, and it works as advertised. There's not much more I could ask for from an extension cable.

Awesome experience

Web site was very helpful to make sure I had the right replacement plug and it arrived in a few days.
Had to cut the plug end off to replace a hard wired plug from an old Halloween decoration but it worked and saved a 25 year old holiday decoration.
