Camco Power Defender 30-Amp RV Surge Protector (55301)

$69.99
★★★★★4.7(5,100 reviews)

The Camco Power Defender 55301 is a 30-amp RV voltage protector and surge suppressor designed to shield your RV's electrical system from dangerous power conditions. With 2,800 joules of surge protection, it automatically cuts power when voltage drops below 102V or surges above 132V, then reconnects once stable levels return. Diagnostic LEDs on the unit show open ground, open neutral, and reverse polarity wiring faults at a glance. The weatherproof housing and Power Grip handles make camp-side setup easy even in rain.

Why You Need This

One bad campground electrical pedestal can fry your RV's entire electrical system — the Power Defender catches surges and voltage faults before they reach your rig.

🏆 How It Compares

The Camco Power Defender 55301 offers 2,800 joules of protection with auto-shutoff and diagnostic LEDs at $69.99 — beating most competitors that charge $90+ for fewer joules and no weatherproofing.
