Jim,
See if you can find the circuit breaker/fuse that is protecting this outlet.
Find it's rating, also find out what else, if anything, is plugged to this
circuit. It is likely a 15 or 20 amp device. If there is nothing else on
the circuit the 15 amp outlet is good for 1500 to 1750 watts, the 20 amp
outlet is good for 2000-2400 watts. Subtract anything else plugged from
what your using from your extension cord.
16 gauge - 1000 watts / 10 amps
14 gauge - 1500 watts / 15 amps
12 gauge - 2000 watts / 20 amps
These are conservative ratings based on a low voltage ( <110 ) and
continuous usage, real world use can be higher by about 10 %.
I'd use at least a 14 gauge cord for power tools that will run with lights
etc., you'll get less voltage drop and your skilsaw will be happier. Your
fine with what you've got though, even with all those battery chargers lined
up. Your cord speaks the truth.
