I just realized I hadn't stressed a point. There really is only one electrical outlet in a cabin! I took a surge protector from my office that had 5 extra plug ins. I do not suggest when drying your hair with a normal dryer to have anything else plugged in!!!! I blew a fuse or something when I had the concentrator and blow dryer plugged in at the same time. Remember this was a heavy duty stip used to dealing with lightening and computers. You will need the strip though!
