Simply plug one end of the first extension cord into the adapter or power strip, and then plug the second extension cord into another available outlet on the adapter or power strip. This allows for the extension cords to be connected in a safe and secure manner, while also providing additional outlets for other devices. It is important to ensure that the total power draw does not exceed the capacity of the extension cords and the outlet. **
