Protect your investment

If you aren't using a surge protector, you're taking a big risk. While spikes caused by lightning can damage your electrical system and appliances, there are common electrical issues that can be just as dangerous. Choosing a surge protector with advanced features will help you protect your RV.


Beyond Basic Surge Protection

The most affordable RV surge protectors will provide basic protection from voltage spikes caused by lightning or other transmission issues. They can typically withstand a few minor spikes, or only one major spike, before they need to be completely replaced.


Power Watchdog surge protectors go beyond the basics. Plug it in before connecting your RV to get a clear indication of any wiring issues at your park pedestal. In the event of a major spike, you can replace the surge protection module itself rather than the entire unit. The modules are plugged in without soldering, so you don't need to be an expert electrician to make an easy repair. In fact, the only tool you need is a screwdriver.


Information at Hand

The Power WatchDog smartphone app

The Power Watchdog app lets you connect to your surge protector via Bluetooth. You can monitor your energy usage, making it easy to diagnose any ongoing energy issues you may be experiencing. When voltage increases or decreases to risky levels, you will be notified right away. You can also reset your surge protector without stepping outside.

About a year ago you purchased a Hughes Autoformers Power Watchdog Surge RV Surge Protector. I purchased this a year ago and have used it many times with no problems. My brothers recommend I get this and the water regulator to protect my new travel trailer.

We have a horrible electric setup at our campground . Power surges spikes etc. Blew our inverters well. Bought this to help stop damage in the future . So far it's worked. Had 2 more surges since I installed it. Saved me time money and aggravation. Well worth the money




by:

The 50 amp Watchdog is a solid piece of equipment. I especially like that I can monitor the RV power system on the fly, from my phone, using the app. Thank you etrailer.

So far it works as promised! The smartphone app does not display all of the info on the screen - the last line is covered by a border.

See what our Experts say about this Hughes Autoformers RV Surge Protectors

  • Can 30 Amp Portable Power Watchdog Surge Protector Be Used On 50 Amp Trailer
    I don't recommend using a 30 amp surge protector on a 50 amp trailer. This would require adapters and will limit power going to the trailer. Instead, for a 50 amp trailer, you'll need to use the Portable Power Watchdog Surge Protector with Bluetooth part # HU47FR.

  • Can Power Watchdog HU47FR Protect Against Dirty Sine Waves
    If the dirty sine wave ends up being an amperage or voltage spike yes the Power Watchdog Surge Protector # HU47FR will protect against it.

  • Recommended Surge Protector For A 50 Amp Generator
    If your generator is producing 50amp power then yes, you could use the Power Watchdog Surge Protector with Bluetooth # HU47FR for extra surge protection for your sensitive electronics. That being said 50amp service isn't enough to power everything in a residential setting. You'll have to prioritize what you want to power and flip off the breakers for non-essential items.

  • Can Power Watchdog Surge Protector # HU47FR be Used at Private Residence
    Yes the Power Watchdog Surge Protector # HU47FR would work great when connected to power at a private property residence. Basically it protects the RV from any power source it's plugged into whether it happens to be at a campground or at a residence. Not a dumb question at all. The power sources essentially are the same for campgrounds and houses though so it's a good idea for either setup.

  • Does 50A Power Watchdog Portable Surge Protector Come with Twist Lock Connection
    The 50A Power Watchdog Portable Surge Protector # HU47FR only comes with the standard connectors but if you want to be able to use twist lock connectors you can use the Hardwired Version # HU27FR instead and use a twist lock connection from your trailer to the pedestal. This gives you the same functionality as the portable one aside from being able to seamlessly move it from one trailer to another. Attached are review videos for you to check out.

  • Availability of Hughes 50 Amp Watchdog Surge Protector with Emergency Shut Down PWD50-EPO
    We do carry the Portable Power Watchdog Surge Protector with Bluetooth and Emergency Shut Down # HU87FR. This is our part number for the PWD50-EPO from Hughes.

  • Recommended Warning Limits For The Power Watchdog Surge Protector With Bluetooth - 50 Amp
    The acceptable power range for the Power Watchdog Surge Protector with Bluetooth - Portable - 50 Amp # HU47FR is between 104 volts - 132 volts, just like with the 30 amp # HU97FR. I recommend placing the low end at 109v and the high end 127v so that you have a 5v buffer to notify you before it gets out of the safe zone.

  • Can the Power Watchdog Surge Protector with Bluetooth Be Used With a Generator
    Yes, the Power Watchdog Surge Protector with Bluetooth, # HU47FR, for 50 amp and the 30 Amp version, # HU97FR can be used with a generator. However, many generators (portable) have a floating ground/neutral. If you do have a floating neutral generator then you will also need the Hughes Autoformers Ground Neutral Bonded Plug for Generators, # HU33FR to bond the neutral and ground thus preventing an open ground or open neutral error fault to occur.

  • Questions on Hughes Autoformers AC Digital Voltmeter & Surge Protector
    The Hughes Autoformers AC Digital Voltmeter, # HU28FR that you linked to is for measuring voltage at an operating range between 108 to 132 volts. This is irrelevant of the amperage supply from the pedestal. If I understand correctly that you are wanting to monitor amps being supplied to your RV, I suggest a surge protector. From Hughes, we have the Power Watchdog Surge Protector, # HU97FR for 30 amp and # HU47FR for 50 amp. The 30-Amp or 50-Amp surge protector offers 2,400 joules of...

  • Replacement Surge Module for Power Watchdog Surge Protector with Emergency Shut Down
    I have a solution for you, but the # HU38FR is designed for the Portable Power Watchdog Surge Protector with Bluetooth - 50 Amp # HU47FR without the Emergency Shut-off feature. Your PWD50-EPO is the Portable Power Watchdog Surge Protector with Bluetooth and Emergency Shut Down - 50 Amp # HU87FR, so you'll need the Replacement Surge Module for Power Watchdog Surge Protector with Emergency Shut Down - 50 Amp # HU58FR.

  • Picking The Correct Surge Protector For Your RV
    Watchdog surge protectors like the Portable Power Watchdog Surge Protector with Bluetooth - 50 Amp Item # HU47FR will need to match your camper amperage to properly function. The adapter from 50 amp to 30 amp will go between the surge protector and the power pedestal and you should have no issues. If you need a new 50 amp to 30 amp adapter I recommend the Power Grip RV Power Cord Adapter w/ Handles - 125V - 50 Amp Female to 30 Amp Male Item # CAM55185. The built-in handles on the each...

  • What Surge Protector Amperage Is Right For My Camper
    When it comes to surge protectors you'll also choose one based off of the trailer and not off of the power source. Since you have 50 amp service trailer you'll need the Power Watchdog Surge Protector with Bluetooth - 50 Amp # HU47FR. You'll connect this to the power cord for your trailer, then connect the adapter to the surge protector, and then the adapter to the shore power. If you don't have the correct adapter or yours is needing to be replaced I recommend using the Camco Power Grip...

  • Using a 30 Amp Power Watchdog Surge Protector With 50 Amp Service
    You can use an adapter such as the Mighty Cord RV Power Cord Adapter Plug for 50 Amp Female to 30 Amp Male, # A10-3050AVP to use a 50 Amp surge protector with a 30 Amp power pedestal, but you cannot use a 50 Amp power pedestal to a 30 Amp service RV or surge protector. Any surge protector should be matched to the service of the RV. Such as the 30 Amp Power Watchdog Surge Protector, # HU97FR or the 50 Amp version of, # HU47FR.

Such as the 30 Amp Power Watchdog Surge Protector, # HU97FR or the 50 Amp version of, # HU47FR being used with RV's that match their respectively rated services. You can use an adapter such as the Mighty Cord RV Power Cord Adapter, # A10-3050D90VP to adapt your RV's 4-prong 50-amp power inlet for use with a 30-amp 3-prong extension cord/Power Pedestal and place the surge protector inline.

  • Recommended Generator Set for 2019 Forest River Salem 30KQBSS Travel Trailer
    I recommend you only consider an inverter type generator. From the specs available to me online, your 2019 Forest River Salem 30KQBSS Travel Trailer is a 50-Amp service with 2nd A/C Prep option. If you have have the second AC unit installed or a 30-Amp service instead, please let me know. But based on these specs, I recommend the Champion 9,000-Watt Dual Fuel Inverter Generators w/ Parallel Kit for 7,000 Running Watts, # CH49FR.
