Very good extender cable. I use this to plug in a 200 watt inverter and clip on to a 12 volt car storage battery when I need to use 120 VAC devices outside my car at a summer home. Doesn't draw much to discharge the battery until I can put a charger on the battery. 2 ft length is OK as the inverter has a long cable with a cigarette lighter plug on it. Cover cap on this cable is very nice to keep dust and dirt out of the female socket. And the fuse and holder is great in case I short out the alligator clips, which has never happened but better to be safe than sorry.
