Note:
This converter's female side will only accept round shaped connectors. You can not use this converter if your power adapter connector is not a round shape. Some Dell power adapters have octagonal shaped connectors, which will not fit the female side of this converter. The  female jack can plug into a Dell or HP power adapter with 7.4 x 5.08mm  male  round shape connector like this:





After you convert the 7.4 x  5.08mm connector to a 5.5 x 2.5mm male connector,  you can use our C series  connectors to convert the 5.5 x 2.5mm connector to other size connectors  if you need. 

Cautions: The 5.5 x 2.5mm connector on the adapter can handle a maximum current of around 6A, which is around 120W at 19V ~ 20V. If you are using this adapter for more than 120W power, you can not use the 5.5 x 2.5mm connector on the adapter. You can cut off the 5.5 x 2.5mm connector and use inside two wires directly.
