Now with new added features for more protection!
Portable whole-RV surge and spike protectors now offer more than twice the rated protection of earlier models. Easy to see LCD display uses plain, easy to understand language to keep you informed of status at a glance. Built-in intelligence lets these units reset automatically at power restoration. Each now shuts off power in the event of an open ground or thermal line/load overtemperature condition, as well as in the event of an open neutral, low (under 102 volts) and high (over 132 volts) voltage or reverse polarity to protect your RV and its electrical components from damage and fire. Continuously monitors for voltage and amp draw (RMS) and reverse polarity (miswired pedestal or elevated ground voltage). Built-in 128 second reset delay protects air conditioner compressors. Two-light LED backup indicators for power and faults. More compact design for easier storage. Easy pull handles on connectors for safety and convenience.

Shuts Off Power in Event of:

  • Open Neutral
  • Open Ground
  • Low (<102V) and High (>132V) Voltage
  • Thermal Line/Load Overtemperature


  • Voltage and Amp Draw (RMS)
  • Surge Failure (light indicates when surge protection has expired)
  • Reverse Polarity (miswired pedestal, elevated ground voltage)

  • 120 volts, 30 amps

    My first version of this product worked fine for several years. My second one worked for about 18 months, then would indicate the power was on and ok, but would not provide power to my RV. I assumed it had failed and bought a new one. I sent the other back explaining that I understood it was no longer in the warranty period, but wondered why it said the power was ok, but I didn't have power. They said it probably took a power hit. I used the third one for several months but started to experience the same problem. This occurred at two different campgrounds, neither time was there any weather issues. I have a voltage reader that indicates 120 volts when I plug in directly without the surge protecter and I have no problems, but am hesitant to do without during stormy weather.
    Pros: Easy installation
    Cons: Shuts down power

    My assessment is as the first one mentioned. Same scenario, weather may have had an effect but wasn't any lightning in the area. This is an expensive item to not perform as expected.
    Pros: Easy installation

    This item lasted ONE camping season! For the amount I spent on this I would expect to get more than one season out of it. We have a seasonal site with low power issues in summer. It worked great by disconnecting the power when the voltage dropped too low. I un-installed it and stored it in my (dry) basement for the winter, when I installed it this year it would not work and shows "error". I checked it on the RV outlet on my house and it does not work there either. Both the campground and the house have power within the normal range. I had seen reviews that this was not the best product due to failures and should have listened!! I recommend that you find another product!
    Pros: As expected, Easy installation
    Cons: Did not last long before failing
