In the year 2018 we had a 30 amp Outback travel trailer. I used a smaller style Progressive on it, and it it simply came up missing one day. Because of our location at the time, I ended up purchasing a new Hughes 30 amp (portable) and I really like it, especially the Bluetooth ability to pair with my phone. Just a few weeks later, Hughes did an upgrade to their program and I was NEVER able to pair with my phone again. I kind of missed that feature, but the unit worked perfectly fine.
Well, JUST a short while after that, we traded campers and ended up getting our Montana that's on a 50 amp service. I ended up purchasing the 50X Progressive (2019) and it has been plugged in 24x7x365 ever since, at home and camping.
I kept the 30 amp Hughes and have had occasion to use it. Actually, it's currently running the camper right now as I type. Sometimes we do land on campsites that have only 30 amp hook-up, so with the adapter I can still plug my 50 amp camper in. Maybe that's not necessary, but I just feel better if on a 30 amp outlet to use the 30 amp protector.
Both units have worked marvelously all these years. I still cannot get the Bluetooth to work with my phone for the Hughes, but the unit does have the lights on the front of it to give me the errors when something happens.
I quit agonizing over use of electricity, how much amperage is doing what and so forth some time ago. The read-outs are a nice feature for sure, but the reality is, I don't need them. I don't care. If the power goes wonky, an error code happens, the unit shuts the camper down, and that's all that really matters. Also, I check the error codes when first plugging in.
Currently, I'm at a State Historic Site in Louisiana and I am the only camper here as this is not a traditional campground. They have a full hook-up site for their "camp host" position. I've been here (back and forth and return again for several months in a row) and have never had issues with the power, until about a week ago. My 50 amp progressive shut the camper down, and I am glad for the read-outs. Turns out, that electrical socket is spiking to 140 - 141 volts and then down to 125 - 126. I plugged into the 30 amp side and using the Hughes right now until someone can get here and figure out why the spikes and high voltage is occurring.
Bottom line, I have found a use for both units and I use both units depending on the environment. Both units have worked well since 2018, flawless, with no issues and both have done exactly what I wanted .... shut down the trailer when dirty power hits and display what the issue is that caused the shut down.
I an only imagine the newer version of the Hughes is even better. I don't need the Bluetooth technology to keep me constantly worried and upset every time there is a little flux in the power. As long as the protectors keep the power inside their specified "tolerance" levels, that's good enough for me. I enjoy camping, not being tied to technology.
