Simple –Super Joule Ringer 2.0—Boxed
This is my “boxed” Simple–Super Joule Ringer 2.0. It was specifically designed for use on my 32 ft. sailboat when I’m at sea for 3 to 5 days. It will also come in handy around the house. It will operate on solar energy alone or a battery pack. The battery pack may be charged by a small solar panel or a wall outlet transformer. It runs on 10 to 12 volts at 50 to 300mA.
