### ⭐⭐⭐⭐⭐ Lifesaver Spare for Uninterrupted RV Power Protection!
*by N***. on May 19, 2025*

The Hughes Autoformers RSP-50-PWD-EPO Replacement Surge Protection Module for 50 Amp Power Watchdog EPO is a must-have backup for my RV camping setup! Designed specifically for the 50A Power Watchdog with Emergency Power Off (PWD50-EPO and PWD50-EPO-H models), this plug-and-play module delivers 6,120 joules of advanced surge protection, with a max spike current of 180,000 amps across 18 MOVs—among the highest ratings available. When my original surge module was fried after a campground power spike, swapping it out was a breeze; it took less than 5 minutes with just a Phillips screwdriver, no soldering or wiring needed. The module’s compact design fits perfectly, restoring full surge protection instantly.The included instruction card made the process foolproof, and I was back to monitoring voltage, amperage, and wattage via the Power Watchdog’s Bluetooth app without missing a beat. The EPO functionality continued flawlessly, auto-shutting power if voltage drops below 104V or exceeds 132V, protecting my RV’s electronics. I love that Hughes offers one free replacement within two years (with proof of purchase), but having a spare (around $60–$80) on hand ensures no downtime, especially as a full-time RVer. My only minor note is to double-check your model (this won’t fit non-EPO PWD50 units), but the clear labeling avoids confusion. Compared to replacing an entire surge protector, this module is a cost-effective, high-quality solution. For RVers prioritizing reliable power protection, this is an essential spare! Highly recommend!

### ⭐⭐⭐⭐⭐ Excellent and Easy!
*by J***E on June 24, 2025*

So simple to install! We love this surge protector, and this has added a lot of peace of mind. We purchased a new RV, and on our very first trip out with it, the campground had experienced a surge, and the Watchdog did its job. This worked great on our last trip this weekend, and we recommend keeping a couple of spare ones on hand in the event you need them.

### ⭐⭐⭐⭐⭐ Good investment
