Progressive Industries earns the top spot on our list with its practical and affordable Smart Surge Protector. As the name suggests, this device is bristling with useful features: it not only protects your RV against electrical surges, but it can also detect any miswiring in the power supply that’s likely to cause problems. When this issue or a surge occurs, three colored LED lights will alert you to the problem.
It’s also tough enough to handle any unpredictable weather you might be exposed to, thanks to its rugged design, which features weather-resistant housing. It’s also thermally protected, to ensure that it won’t overheat during use. With its compact and portable design, range of features, and lifetime warranty, you can count on this protector. It’s available for RVs with both 30 Amp and 50 Amp plugs.
