I was thinking of running a pig tail into my trailer to power three double battery chargers. I was wondering if anyone else has done this and if it is even a good idea. I like the idea of leaving my battery chargers in the trailer and running power from a temp. pole on the job. To take it one step further I had an idea to plug the battery chargers into a lamp/appliance timer and plugging in at home. I really don't know about this last idea?? (fire) Thank in advance for anyones input.
