not advisable. The issue should be much less with a modern fridge
or freezer. They typically only pull ~90W or so. Bottom line you
want to use a short extension cord that is heavy enough for the load.

90 watts where the heck did you get that info.
Must efficient unit will draw about 10 Amps. that mean 1200 watts
on 120 volts. for AC unit #14 wire with max length of 10 feet above
that length you should and must go #12 wire. service for apx. 50 feet
if you run any AC on cord and wire or receptacle is getting warm
consider safety and install larger supply "IT is a must"

I think that 90 watts is for a modern refrigerator.

I think we all agree that extension cords are ok, but they should be made
out of wire that is large enough so the voltage drop is very low. The
longer the cord, the larger the wire.
Wire less than about # 14 should not be used on high current loads at any
length.
