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 600V parameter is about the insulation protecting the user from the dangerous voltages in the wires. Your cord is rated at 600V, so the insulation should protect you from the danger of 600V wires. You’ll find 600V wires hard to find, most power is 120 or 220 volts, so this cord has a margin of safety. It’s intended to be used at lower voltages, including a safety margin, rather than at the edge of danger in a higher voltage situation.
