The problem with extension cords is that the longer they are, the more resistance in the cord. The higher the resistance means the more the voltage drop is. What that means is that your 115VAC after it is dropped by the resistance in the cord may only be 95 volts (depending on the actual voltage drop or length of the cord.) Once voltage drops 108 or so (not sure of exact low voltage) electronics may start to be damaged. So I guess it would depend on the length of the cord. One alternative would be to just run a extension to a battery charger to keep batteries topped off. Then you could run 12VDC items with no worries.
