youjust have to research what you have -- its doing whzt it is suposed to do..most power strips are surge protectors
i hope it is a really heavy gauge cord or your house is gonna burn seems like a lot of crap to run off of one cord.. WOW..i run a 7000 btu ac unit, 3 small fans 1 large a squirel fan a 400 watt hps and a 250 watt off 1 extension cord -- with power strips for most but the surge jsut for fans... if i plug em in hte surge they shut it off the second the ac kicks on from a surge.
