We have a friend that is planning on going camping with us in the coming weeks who has to be hooked up to a breathing machine at night when he sleeps. Unfortunately the camp ground we are going to is very primitive and does not have electricity at the camp sites. I'm trying to prevent him having to cancel and was thinking about the possibility of plugging the machine into one of the 12V hookups in the back of my Treg, my only question is does anyone know if this would possibly work, or am I going to most likely end up with a dead battery? The machine would only be plugged in at night, and for 2 nights total.
