Progressive Industries EMS-HW50C Heavy Duty RV Surge Protector, Black, 50 Amp
Progressive Industries' EMS-HW50C heavy duty 50 Amp hardwired RV surge protector with full electrical management.
Power Watchdog PWD30EPO Smart RV Surge Protector, 30A, Bluetooth, IP65
Power Watchdog's PWD30EPO smart 30A RV surge protector with Bluetooth, IP65 weather rating and emergency power off protection.
Campground power pedestals are notoriously unreliable, and a single bad plug can send a voltage spike straight into your RV electronics or fry your air conditioner. A surge protector, or better yet a full electrical management system, is cheap insurance against repairs that can cost more than the device many times over. This guide compares surge protectors and EMS units for both 30-amp and 50-amp rigs. We weigh joule ratings, whether the unit shields against low voltage and miswired pedestals, portable versus hardwired designs, and the diagnostic readouts that warn you about a faulty hookup before you ever connect your rig.
