Haven’t had a chance to use this adapter yet, but seems to be of a good quality and heavy duty. I’m expecting it to work as it should.

Some campgrounds have 50 plugs at the campsite my camper can’t handle 50 so this device gives me the 30 amps that works for me. The construction seems to be solid and heavy duty should be no problems. I just wish there was an easy way to lock the cables together as connector thieves are always on the prowl.

This works great. We use it for a generators off grid. This is a great quality and well built device. Happy with the design and feels like it will last forever.

I own an RV Park and have seen devices like these protect the electronic equipment and appliances in the RVs. Plus, the missing neutral, open ground, and reverse polarity indicators are something that I highly recommend for any RV owner! I have no way to test the surge protection capability of the unit without destroying it, but if it can absorb the energy listed, this is a good product at a great price. I will update the review and possibly move it to 5 stars once I get more time in the field with it.

Sturdy device seems to be well made: Easy to use this adapter and easy to read the very useful circuit analyzer with surge protector.

Nice RV Power adapter with surge protection built in. Appears to be well constructed. Will put to the test this summer. If there are any issues, we will update our review. Looks good so far!

Features:

This adapter is made for campers to go from a 4 prong to 3 prong service easily. 50 amps to 30 amps quick as plugging it in and you are good to go. This item is largely self-explanatory. Its very easy to use, and the indicators on front light up showing you the proper configuration, or lack of proper installation. Stow this in your camper in the side box, and the next time you run into a campground with a 4 prong, but your plug is three, use one of these and there will be no hassle. Of course you can only pull 30 amps, but honestly most folks dont even pull that much power camping regularly. Item was well made, and I would definitely purchase it again. It is bulky, but that is what you want with an item that handles heavy current.

This item continuously tripped the breaker in my house with RV plugged into shore power. Purchased a new item from separate supplier and have had no issue. Missed Amazon window to return.

This was exactly what we needed for our camper! This surge protector works so far as I can tell. I mean we plugged it in and it hasn’t had any problems whatsoever. No worries about shorting anything out anymore while it’s parked at the camp site.
