I have a small GFI (ground fault interrupter) that is intended for portable use -- the tag says Tower Mfg. Co. model 30339 (similar to this). It's like a small wall wart with a standard 120 VAC 15 A plug on one side and a 15 A outlet on the other side.
This GFI specifically states "Do not use extension cord between GFCI and power outlet".
I was curious why they restrict such use. The only thing that comes to mind is that the extension cord wouldn't be protected and sometimes they have outlets in the middle of them. Are there other reasons?
