Review on POWSAF RV Surge Protector 30 Amp: Power Defender Voltage Protector/Monitor with Surge Protection (4100 Joules) - Designed with Convenient Handles… by Jimmy Jefferson

We use RVShare to rent RVs and the last thing we want to do is return the fried RV to the owners. So. We bring our own protection and it worked. From the flat, dusty lands of southern New Mexico (where dust storms are eliminated for a week) to the 800,000 acres of Big Bend, this thing has protected us from the pesky Texas power grid the whole time. Did exactly what was intended.
