I have had the Progressive Industries 30 AMP portable EMS unit since last year and it saved our A*** several times on 1 camping trip with a NY State Park( Cayuga Lake State Park) that had a constant OVERVOLTAGE issue! The unit shut off our power several times a day when the volts were too high and prevented thousands of $ of damage! Amazingly, park rangers KNEW they had a problem and said it had existed for several years but there was not a budget yet to correct it! Said most campers do not have a sophisticated unit like the Progressive and do not realize the damage they are incurring that may not show up for a while but will shorten the life of electronics! The very next NY state Park had undervoltage and our EMS shut down power several times! DO NOT BE WITHOUT ONE OF THESE! Lifetime warranty also!
