I have a (25FT) heavy duty extension cord rated at a maximum of 600V and 14 AWG. Given to me from a friend while moving I think he used it for a generator. Can I still use it for small stuff like a computer or drill or lamp or fan? Just thinking about a voltage loss because of thicker wire or would this not make enough of a noticeable loss if any ? Trying to see if I would ever even use it.

The cords themselves don’t have a lower limit, but the devices that run them might. If your extension cord has too much resistance, there could be too much voltage drop over it and therefore not enough to power the appliance at the end.
One thing to note, a thicker wire would actually be less resistant than a thinner wire; it’s longer wires that have more resistance than shorter wires.
