The next camper surge protector to make our list is Technology Research’s 50 Amp guard. The simple to use plug and play technology easily identifies any faulty wiring in whatever power source you connect your RV to, and can shield your electronics against surges of up to 4,200 joules.
A clear indicator system, on the front of the surge protector, illuminates to show whether the power source it’s plugged into is functioning as it should. Users say the surge protector is tough enough to handle almost any weather condition – be it snow, rain, sleet, or a baking hot sun. Whenever the guard absorbs a power surge, it will automatically reset itself for future use, making it a great investment that can protect your electrical gear for months and years to come.
