rv surge protection comparison guide

We have put together these comparison charts on RV Surge Protection devices available by Surge Guard, Camco and Progressive Industries. We have evaluated products from all 3 companies and found quality, functionality & reliability to be excellent by all three manufacturers. Products are grouped in 30 & 50 amp, portable & hardwired versions. These charts will give you a better understanding of the available functions each unit has relative to the price of the product.

11/6/15 UPDATE: We have gone through and updated the comparison chart to the most accurate information to date. What you will find new is the addition of Camco's Power Defender series of portable surge protectors. While they do not display voltage readings and error codes like the Progressive EMS & Surge Guard upper end units they do everything else and the price is quite attractive, so be sure to give these a look. Also just added are the updated Progressive Smart Surge portable units (their mid level surge protectors) with the protective cover and UL certification. And not to be out done Surge Guard also made some updates to their full feature portable units with a LCD voltage display and remote display capabilities for their hardwired units. And more recently released an entry level unit that delivers surge protection along with mis-wired pedestal warning indicators.

Please Note: specifications & prices are subject to change without notice, please use these charts as a reference only.
