Best RV Surge Protectors
As an Amazon Associate I earn from qualifying purchases.
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.
