NOTE - Two common issue experienced when buying a DC power extension cable.  1. Wrong Plug Size - This is the most common problem. Please check your device by measuring the barrel plug of the power adapter. This will only accept 2.1mm (inside diameter) x 5.5mm (outside diameter) plugs.  Manufacturer do change their plug size for their models from time to time. The surest way to know if this cable is compatible or not is to measure the plug size of the power adapter that this cable is intended for by measuring the inner diameter and outer diameter of the plug of the power adapter.  2. Lack of Power - The longer the cable, the more resistance and power loss, and hence requires more power from power supply. Most commercial products do not provide a strong power adapter. At 20ft length, the power loss is noticeable.  Please make sure you have adequate power supply to use extension cable  Package Included:   1x 10ft Power Extension Cord (Black)
