It depends on what he's going to run from the generator. As a reference, the
small compressor I have will run the first time and pump up to the shutoff.
Anything else after that it suffers. Starts, Stops before the shutoff. I was
using 50ft of 14 guage. It works fine when plugged directly into the outlet or
using a heavier gauge extension. At first I thought it was overheating and put
a fan on it, and it helped slightly but it kept having the start issue until I
plugged in directly to the outlet. That same extension has issues running a
14" fan from a small inverter too, but it runs lower demand items with no
problems. Similar findings as the compressor. Works fine when plugged directly
into the inverter. The 12g extension is pricey, but if needed, get it.
