M1A2 New Generation RV Surge Protector 30 Amp 50 Amp with Waterproof Cover Camper Anti-Theft Circuit Analyzer Tester Plug with UL Tested

easy to use, and used more than I thought would

To keep my Travel Trailer on while not in use.

Use on outside outlet to protect my travel trailer. Great for the $$$$. Easy to use & read.

All good

There is another photo evidenced 2-star review from another purchaser. I’m sure this review will get buried but this randomly happened during my parents 3-week stay at a lake RV resort. Circuit analyzer melted where my parents RV power cord connected into the analyzer. The resort’s power plug was fine and so was the top plug of the analyzer as evidenced with photos. Did not cut the power when there was an obvious abnormality in the voltage resulting in a burn that ruined the analyzer and parent’s RV power cord. So I do not recommend it for reliability.

I was told by another RV person that if I put the adapter on and plug this in to 50 amp I have a fear of ruining it. I usually plug in the 30s but if the 50 opportunity was the only outlet available somewhere, I wish I had bought a 50 amp

Theres not much to say it seems to be working. Havent had any issues with it yet.

This is a great little unit. The circuit analyzer shows you quickly if the power post is wired correctly or if theres an issue that may hurt your electrical service in your camper AND it guards against voltage spikes. Plug the unit into the post, verify that all is well, then plug your campers power cord into the surge protector. Over and done. Simple to use, great value. The cover may be a bit tight or not close entirely if your male connection is oversize. Itll still works just fine though.

Great product. So easy to use and makes hooking the trailer up to electrical so fast and easy!

Nice unit, I like the rain cover and lock.
