I have been using the Hughes Autoformer for one year now and am very pleased with the results. I purchased it over the EMS unit because of the many state parks I have been in during my outings that had low voltage. It does raise low voltage and will allow electrical devices to operate as designed. It will also protect against park power problems. The EMS units just go off when voltage hits a certain point. I did not like that feature. Low voltage has always been my biggest problem and this does a great job handling that. You really should go to their web site and read what the Autoformer can do for you.
I would buy this again with no hesitation.
