my biggest concern would be bad campground power frying my DC power converter.
I have the same Progressive surge protector as you
I have had to make repairs / adjustment to it on several occasions and saw no components that were capable of boosting or lowering voltage
It appears to be nothing more than a monitor that shuts the power off when the voltage goes above or below the set perimeters and clips small spikes in the voltage . Mine has been in the bypass mode for the last 8 months without ill affects . It will probably remain in the bypass mode in the future .
In a trailer equipped with standard features the only thing I see is that it protects the A/C from low voltage . It provides little or no protection for the 12 VDC system ( Refrigerator control board , furnace control board , roof fan.)
When we go camping the only electronics we carry is a cell phone , which may or may not work in the area we’re in .
On our last trip out West we had no TV or cell phone service for a week and survived.

I am sorry the OP took my posts the wrong way but when you ask a question you have to expect you will get honest answers that don’t agree with your position

My dad smoked cigarettes all his life and never died of cancer.

Didn't waste our money on a surge protector. Then one day we came back to our Casita and our power center/converter was fried. There were at least three others near us in the campground that either fried their power centers or air conditioners. Cost over $300 to replace the power center, including installation and lost a couple of weeks of camping. I wonder what it cost those who lost their air conditioners. We have a Progressive Industries EMS wired in to our camper now.

One thing people need to do is check their wiring once in a while. I did in our Casita, but some sort of brownout fried us and the neighbors, not bad wiring in our camper. It happens more often than some people realize.

After actually having a fried power center it gives us peace of mind. I could care less about the contrarians, especially one in particular that seems to have way more problems than others and loves to complain about them. Glass half full or half empty?

Enjoy,

Perry

simple cheap answer. Get rid of the expensive "power center". Live off grid. No more problems.

Live off grid? So your Ram requires no fuel, nothing?

That's your response?
OK Dakota. Does that make it better?
You're still on grid.

time to step back into the corner people, everyone has an opinion, no reason to make it personal.
The reason I joined this forum was for the sharing of ideas, not their bashing.

Campgrounds have notoriously poor AC power distribution. Power connections at each site are subject to moisture, poor connections and lack of proper ground. Additionally there are dozens or hundreds of other trailers on the same circuits that are constantly cycling the power on all of their devices. All of these things can cause major fluctuations in the line voltage at your trailer. So you should use a surge protector for your entire trailer because several of the installed devices (refrigerator, air conditioner, furnace, TV, stereo, etc) have sensitive electronic components.

Surge protectors use a couple of different technologies to limit surges so that they do not destroy your equipment. Metal Oxide Varistors (MOVs) are the most common. These are themselves a semiconductor device. They can block a surge as short as 3 nanoseconds (0.000000003 seconds). The other most common technology is a Gas Discharge Arrestor. These use a tube filled with a gas that presents a short circuit to ground for surges.

Both of these technologies work well but may need to be completely replaced in the event of a large surge because the component that protects your equipment commits suicide for the cause. For this reason alone I would not use a built-in surge protector unless it is trivial to replace and you carry a spare with you. Otherwise you might find yourself without any power at all after a surge. With an external or in-line protector you can simply not use it after a surge until you purchase a replacement. Also many surge protectors for RVs have an internal fuse which may have to be replaced after a surge. So if you cannot easily get to the protector this may also leave you without power.

based on the size and weight of the progressive EMS stuff, I assumed it had a multi-tap transformer in it, similar to the nearly antique (early 70s) AC power conditioner I've used on stereo equipment for field recordings. but with hindsight, that AC regulator was only 200 watts, while one of these trailers is like 3600 watts, so....

We have the Progressive EMS in ours. Other than waiting a while to be able to use power while it does its checking, it's been great and glad we have it. The previous owners had Escape install on build.

On this latest trip at one campground I got two errors when plugging into the 30 amp. Fortunately we carry a 50-30 plug which we got years ago when staying at a park in Tucson with only 50 amp connection. I wondered why I carry it but glad I do as the 50 amp on the same power post worked just fine.

I wonder what kinds of problems Steve had (see post #3) which caused him to bypass the EMS which I'm sure is the same model we have. Overall through this thread the general opinion is that it's good to have. I also wonder whether Steve does all his typing on his phone since he said he has no computer or laptop at home

Portable surge protector?

Before buying my recent camper, I persuaded myself that a portable surge protector would be adequate. But after looking over the selections on Camping World and Amazon, it seems that I may have been naive. The built-in models feature a faster reaction time and automatically shut down the system if voltages are unstable or drop below a certain level. As far as I can see, the portable models have a moderate reaction time and do not react to low voltages. Hence purchasing one of these appears a waste of money. Am I wrong? Comments or corrections welcome, along with recommendations for a portable surge protector!
