Kohree 50 Amp RV Surge Protector, 20,000 Joules with Circuit Analyzer Large LED Display Auto High/Low Voltage Protection for RV Camper Travel Trailer

Replaced an older model. The updates on this one make for easier use. Does a good job

Cord could be a little longer to bend to ground and attach to camper electric power cord. All else is very good!

This RV surge protector and electrical analyzer was a great bang for the buck, easy to use, and works just as advertised. Before you plug your RV in at the next campground, I highly recommend to plug this surge protector analyzer in first!

Only reason for the 4 instead of a 5, I wish it had a delay to check for voltage and circuit before powering up electricity to the camper.

We are full time living and this surge protector kept shutting down our electric!!!! The entire coach would go powerless and then come back on 10 to 15 seconds later and this continued all evening from 4 pm until midnight when I could not could not take it anymore and was worried it was gonna ruin or destroyed my ACs. It's just too sensitive and shutting down the Rv every 10 minutes is not acceptable May work for other RV's

Did work for RV, kept shutting power off and back on about every 10 minutes. No error code showed. Sent it back to you today. You credited our a count already too.

I meet all the requirements for usage. but as soon aa plugged in my electricity started going off and on eveey 3 seconds. as soon as got it unplugged and didn't use my electricity wasfine.

Didn’t work. The unit kept clicking off. Purchased a different device which worked fine.

Did not work. Power flickered on/on every few minutes. Returned for refund

so many problems with breaker going off. once I bought a different brand it was fine
