CARMTEK RV Surge Protector 30 Amp - RV Circuit Analyzer with Integrated Surge Protection - Smart 30 Amp Surge Voltage Protection with Grip Handles

It is only a 3 prong adapter. I needed a 4 prong adapter. Never saw any info on how many prongs. Didnt know the campgrounds needed a 4.

Provides comfort knowing you have protection.

It does what it’s suppose to do!

My old surge protector does not include a circuit analyzer. From what RV owners have told me, we all need the circuit analyzer. This is exactly what was needed, and it is so easy to use. Provides great peace of mind. If you have a RV that works on 30 Amp, you need this. I was informed that many of the RV parks have faulty wiring. This will show you when that is a problem before you plug your RV in and have massive electrical damage. Nice, simple solution. Buy it! It could save you a lot of repair dollars in the future.

Good product

Works like it should

Easy and works great.

We bought a new toy hauler, and after reading several reviews, and doing some research, we decided to go with this surge protector. Plugged it in to the electrical meter at the park and into our coach, and the lights are lit up showing correct wiring, but the coach showed that there was a short to ground and the surge protector. Luckily, a friend of ours had an extra one, a different manufacturer, and we use that one and had no issues. So we did a return to Amazon.

Checks circuit conditions & offers some surge protection

Not to much to write about this. I have used it a few times and it works as expected. Plug it in and it lets us know about the voltage. We have not had a spike in voltage to see how well the surge protections works.
