RCGUY,

The only problem with using 2 "Male" plugs on an extension cord is......

If someone was to accidentally knock the plug from the receptacle, you would have a LIVE exposed end laying on the ground......also, if you forget and plug the power side in first, there is a great potential for getting shocked. This is not a very good situation, especially if children are around.

There is a reason that the "Proper" electrical devices should be used.
