Easy-to-Replace Surge Module

All surge protectors and voltage boosters by Hughes Autoformers feature modular surge protection - meaning that if a surge occurs that would have damaged your RV, the surge module will be damaged instead. Due to the modular construction, you can just take out the damaged part and replace it with a new surge module instead of purchasing a new surge protector.

    Easy to use with little electrical knowledge needed

    Easy to hook up and test the power source before connecting to the RV. Protects the RV systems and helps diagnose issues. Having the monitoring data and alerts on the app is really nice. 👍

    Great Surge Protector, and love the bluetooth info

    My RV has a Surge Guard Transfer switch with surge protection, but I wanted something more modular in front of it to protect it. This unit is great. The white face to let you know you have a good power and the ability to monitor it through the bluetooth app is awesome. Way more information than I could easily get from my Surge Gaud. Very happy with this purchase.
