Get full electrical protection with automatic shutoff in the next generation of the world's best-selling RV surge protector — the Hughes Power Watchdog Gen II 50 Amp WiFi Surge Protector with Emergency Power Off (Part #PWD50EPOW). Reimagined from the ground up, the Gen II combines enhanced weather protection, improved security, and unmatched ease of use with the added safety of automatic power cutoff during voltage faults — built for larger rigs running 50-amp service.
Emergency Power Off — Automatic Protection
What sets this model apart is its Emergency Power Off (EPO) feature. The unit automatically shuts down power if voltage drops below 104V or rises above 132V — the dangerous conditions that damage RV appliances and electronics. Once power has been stable for at least 90 seconds, the unit automatically turns back on, ensuring any fix is permanent before power is restored. No babysitting, no manual reset.
A Complete Power Management Ecosystem
The Power Watchdog is far more than a surge protector — it continuously monitors for a range of faults multiple times per second and alerts you the instant it detects an issue. When a problem is found, the unit turns red and displays the specific error code (one of nine potential faults, with a code key printed on the side), while sending an instant notification with a detailed explanation to your phone. A glowing white indicator confirms safe, normal power at a glance.
Built-In WiFi & Bluetooth with Remote Control
Built-in WiFi and Bluetooth let you monitor and manage your RV's power from anywhere in the world — no extra hardware required. The redesigned mobile app lets you adjust light brightness, track past faults, monitor energy consumption, reset the energy meter, and remotely cut or restore power to your RV. The integrated energy use meter helps you avoid surprise fees at parks that bill per kilowatt-hour.
Innovative, Weatherproof Design
The Gen II's lockable, lit clam-shell connection bay makes connecting in the dark easy (the light dims or turns off via the app) while providing outstanding weatherproof protection to keep your connections secure and dry. For security, the clam-shell door includes a padlock ring on top of the standard cable lock ring. The patented side-entry receptacle provides a balanced cord arrangement that relieves stress on the connection for added longevity.
Replaceable Surge Module
The patented replaceable surge module keeps your protector effective even after a massive surge — on Gen II models, the compact modular design allows quick, easy replacement with simple hand tools, instead of replacing the entire unit.
