Progressive Industries 50 Amp Portable Surge Protector Kit, PSK-50

I like it, easy to use an accurate. Can save you a lot of headaches at campground pedestals by testing them before plugging in the camper. They make excellent RV surge protectors that I have also been very happy with.

Purchased to use with our travel van. Well made unit. I like that the tester and surge protector are not joined as one unit, those are bulky, hang down from the power source and exposed to the elements.This works great. Use the tester alone first to check power source with out plugging in, then if all is ok plug in using the discrete surge protector.

I always wanted a surge protector/ circuit tester for my RV. Never got around to buying one to hardwire into RV. I was always worried that someone might steal a portable device I didn't trust the locks/ guards sold for them. This is the best option for me - plug in the circuit tester, easy to read and understand condition of electrical supply, if it's good, remove circuit tester, plug in the shoreline - store the tester. Use the surge protector by itself if you need it. No theft worries of circuit analyzer.

The unit seems very well built. I have used it three times, and once it detected the Ground was missing, so I'm glad I had it.

Have used surge protector for about 6 months and has worked exactly how it was described. Great quality product for the price. And has very easy instruction

Make sure the power post at campground is wired correctly. You do not want the outside of your camper electrified. I have not tried the surge suppressor, but it is good to have if there is a storm. Cheaper than a new converter.

It saved my travel trailer from a major surge!

We work camp and in the park were in now it has clean power. I have one 30amp and one 50 amp tester. Sometimes campers come and tell us their surge guard says the polarity is bad and they can't use our power. This is where the Progressive shines best. Plug it in and it shows everything is fine. Which I already know it is and their surge guard is wrong. If they don't trust the proof given from the progressive tester they are left with 2 options. Do not hook up or we can call a certified electrician. If he says it's our fault will pay to fix it and pay him. If however he says there is nothing wrong then that customer has to pay him for his time. No body has taken us up on that offer. LOL. They plug up and everything is fine for their stay.The worst part is you can show them were that sites power was used that very day by a guest who left or the one before that and yet they still don't believe you. They are trusting a surge guard that is just not that good and then you have to prove it to them. These Progressives are very good at testing and Not only do I use then to prove the power is good I use them when we are on the road in our camper as well.

Been using these for a couple of years with no issues.

Seems to do what is is supposed to. Love the smaller footprint.

Product is well built , has the handy lights to tell you if you have a good connection or bad connection. Very pleased with the product and I highly recommend it.

Je l'ai acheté suite à une recommandation de mon association de camping et de caravaning. Je l'utilise depuis quelques semaines et je n'ai éprouvé aucun problème à date. Le futur nous en dira plus.
