** The product I plugged in does not work:** Make sure the plug is inserted all the way in the socket, the power is turned on and that the device actually works.
Remember that you are running multiple devices from one outlet; Don’t plug too many high power things into the extension cord.
Purchase a cord with built in surge protection. They are not that much more expensive and will protect against minor power surges (as you could probably infer from the name).
Thanks to Harrison AO554 for suggesting this tutorial. Hopefully this helped him plug something into an extension cord.
