Review on ⚡ TRC 44750 Surge Guard 30-Amp Portable: Enhanced Safety with Shock Shield by William Turner

We have used this surge protector with our trailer at every stop on our trip in the Seattle area and along the Oregon Coast and it has worked well for us. It provides basic overvoltage protection, as well as limited circuit tester capabilities and a "master" on/off switch that controls bus power. The unit ran in very humid conditions, including a torrential downpour one night in Seattle, and it worked great - we had no crashes. I'm giving it 4 stars instead of 5 because I think the price is high for the fairly basic functionality and limited surge protection it offers. Just remember that you have to pay a little more to get more.
