Power Watchdog Gen II. The RV Surge Protector That Actually Protects Your Rig.

September 19, 2026
Disclosure: Power Watchdog gifted this product in exchange for an honest review. All opinions are my own.

RV park power is not reliable. Low voltage, high voltage, open ground, reverse polarity — these faults happen at campgrounds all the time and most RVers have no idea until something expensive is already damaged. The Power Watchdog Gen II monitors your power connection continuously and cuts it off the second something goes wrong. This is not optional equipment for full-time RV life.

What It Does

Why This Matters

A single electrical fault can destroy your slide motor, your AC unit, your refrigerator, or your entire electrical system. RV repairs are expensive and slow. A $449 surge protector is cheap compared to a $3,000 repair bill at a campground two states from home. The Gen II does not just protect — it tells you exactly what is wrong, from your phone, in real time.

The App

The Power Watchdog app shows your current voltage, amperage, and power usage. When a fault trips the shutoff, you get a push notification with the fault code. You can also toggle power on and off remotely — useful if you're at the pool and want to check on the rig without walking back to the site.
