Letter Re: An Odd Piece of Equipment for Your Preps


I saw the “Odds and Sods” post about tens units. The writer was disappointed that his unit was 9 volt and did not use AA. There are a few ways to convert 9 volt systems to run on AA, but I thought I would share this way, as it is the easiest. Obviously there are other versions out there, so it doesn’t hurt to shop around. I hope this helps. – R.M.
