This is sort of like a splitter... one end plugs into an iGo power supply adapter which has a round "dualpower" plug. The other end of the cable takes an iGo tip. It adds a second cable for another tip to your iGo power adapter, BUT, you cannot use this product unless you have a round dualpower plug on your iGo power adapter. This cable does take either the grey tips (laptop) or the A tips, whereas my original iGo-85 dualpower cable only supports A tips. A nice product if you can use it. Well-made and compact.

For the life of me I can't figure this out. I bought it thinking it was a splitter. unfortunately I lost the receipt so I couldn't return. It has a DC Barrel input. But the Voltage, current and polarity are not stated on the part. [...].
