Video Transcript for Replacement Surge Module for Power Watchdog Surge Protector Feature Review

What's up everybody, it's A.J. with etrailer.com. Today we're gonna be checking out this replacement surge module for your 30 amp Power Watchdog smart surge protector without EPO. This is gonna be that part that you replace on the inside here after a few surges and down the line at burns out, you don't have to buy a whole new unit you can just get this part, we're gonna open it up and put it in there. You got a Phillips head screwdriver, I'm gonna remove these six screws all around. The next step is just to unscrew the cap on the plug side, and now you should pull it apart.

Now we're just gonna start pulling apart the plugs, getting that out of the way. All I have to do, is under these three screws here, pull out the bad board and set the new one back in its place. Now we'll just put all the screws back in. With the board screwed back down, just put the plugs back together and just reassemble the whole thing. Really was that easy.

We just used a screwdriver and got them pretty quick. Replaced that board on the inside. Now it should be working like it was brand new. I really like the fact that you don't have to buy a whole brand new one, you can just replace that easy part yourself and now you know how to do it too. Well, thanks for hanging out and I hope this helped..

Ordering and shipping went well and the unit arrived in good shape.

When I ordered the Power Watchdog I liked the idea of the replaceable surge module, the LED status lights that I can use to test the power pedestal plug before I connect my trailer to it, and the ability of the unit to measure the voltage and current and bluetooth that information to an app on my phone. Should there be a power surge, this unit will be one more level of protection for the electronics in the trailer.

I connected the Power Watchdog to power today and connected the trailer to it. The LED lights all lit up green indicating all was well. I downloaded and tested the IOS app that comes with the unit. It is basic, but seems to get the job done. I could see the voltage and current draw of the trailer in "reasonable real time". As I turned items off and on in the trailer, the current draw measured by the Power Watchdog would change showing me the draw of all the electical items on at that time.

So far it works as advertised.............I am looking forward to using it on the next camping trip.

After a year, the Power Watchdog continues to work great. I use it a lot to check the condition of the parks power pedestal before I connect my trailer. I also like the fact that I can connect to the unit via the Bluetooth app and monitor the voltage and current being drawn by the trailer. So far the unit works as advertised. I am looking to add some form of cover to the load plug of this unit to help shield it from moisture. I have not had any issues with this, but considering the rain that I camped in during the last trip, I would prefer the electrical connections not be exposed to rain.

I have been looking at this Surge protector for a while now. My brother was camping in a private campground this Spring when he began smelling Smokey. When he went to where he was getting his power from his Surge protector had already fused together. Needless to say it saved his RV. This Watchdog Surge protector since it has Bluetooth can warn me a head of time regarding the Campgrounds wire integrity. Thank you...I have been shopping etrailer sometime since 2009.

This is my second purchase from etrailer. The first was a brake controller as I was new to pulling a camper. Both purchases were delivered flawlessly and quickly. The brake controller was as advertised and has worked like a charm. I am confident the new purchase will too should I need it. (It's a replacement module for a surge protector).



by:

I bought this to have on hand if needed. Great feature to be able to change out the surge protector module on the 30 amp power watchdog. So, have not installed this but, I'm sure glad I won't have to buy a whole new power watchdog if the module wears out.



by:

Have not had to use it yet. Glad for the peace-of-mind having it.

  • Can 50A Surge Protector Be Used to Connect and Protect a 30A Camper to 50A Service
    Hey Michelle, thanks for reaching out! While that will technically work, the problem is that the surge protector is for 50 amps so it won't really do your 30 amp setup any good as it won't trip until that 50 amps is exceeded. For your application I recommend using the Power Watchdog Surge Protector with Bluetooth # HU97FR so it's accurately rated to protect your camper, plus if the unit ever does experience a surge you can replace the module with part # HU48FR and we have a video showing...
