Hughes | Watchdog Gen II – 50 Amp WiFi Surge Protector | PWD50W | Bluetooth | Portable

Meet the next generation of the world's best-selling RV surge protector — the Hughes Power Watchdog Gen II 50 Amp WiFi Surge Protector (Part #PWD50W). As the successor to the original Smart RV Surge Protector, the Gen II has been reimagined from the ground up to deliver enhanced weather protection, improved security, and unmatched ease of use for larger rigs running 50-amp service.

Smart Protection with Instant Alerts

When a problem is detected, the Power Watchdog turns red and displays the specific error code, while sending an instant notification to your mobile app — so you're always informed, no matter where you are. The error code indicator covers nine potential faults, with a code key printed right on the side of the unit for quick reference and a detailed explanation delivered to your phone to help you resolve issues fast. The unit continuously monitors for faults multiple times per second.

Innovative, Weatherproof Clam-Shell Bay

The Gen II's standout feature is its lockable, lit clam-shell connection bay. The integrated light makes connecting in the dark easy (and can be dimmed or turned off via the app), while the weatherproof clam-shell door keeps your connections secure and dry in any conditions. For security, the door includes a ring for a padlock — on top of the standard lock ring on the cable — adding serious tamper resistance to keep your investment safe at the pedestal.

Built-In WiFi & Bluetooth Monitoring

Gen II Power Watchdog protectors come with built-in WiFi and Bluetooth, letting you monitor and manage your RV's power systems from anywhere in the world — no additional hardware required. The redesigned mobile app lets you adjust light brightness, track past faults, monitor energy consumption, and reset the energy meter, helping you avoid surprise fees at parks that bill per kilowatt-hour.

Replaceable Surge Module

Like all Hughes surge protectors, the Power Watchdog uses a patented modular surge design. If a damaging surge occurs, the surge module takes the hit instead of your RV — and you simply swap in a new module rather than replacing the entire unit.

Replaces Legacy PWD50

The PWD50W is the direct replacement for the legacy PWD50 part number, so it's the right choice if you're upgrading or replacing an older Power Watchdog 50A unit.
