RV Surge Protector 30 amp,Smart RV Power Defender Voltage Protector/Monitor with Integrated Surge Protection, Defender for Camper, Trailer, Truck, Motorboat, Yacht, Mobilhome (Blue)

I always thought having one of these would be a good idea, since you never really know what kind of condition the post you plug your power into really is. This unit is larger than I expected it to be, but it is solid and feels like it'll last a long time. So far, this thing has worked great! It has so far properly shown open ground/open neutral issues at a few campgrounds. I have been able to verify the wiring faults with my multimeter. The cool thing with this plug is it's an instant result. You plug this in first, then you know what your dealing with before you plug in your camper. I'm not sure how good the surge suppression is, but as I said, it seems to be a solid unit, so I'm pretty confident adding this is still better protection than nothing at all!

The price is right around average on this unit compared to other budget options on the market. I'd recommend this to anyone with a 30amp service on their RV that wants an affordable but quality option for shore power at their campsite.

very high quality build....
might serve a great purpose....
the only problem is, I can not assure it does, unless I have a surge! and know about it...
I will have to trust the maker here, as there is no way I am testing it ...hee hee...
considering what you have downstream, it only makes sense to protect your investment...
4.5 stars, recommended!

Ordered this to add to an EV charging circuit. It’s actually got blue ends, not yellow. There’s also no CE, ETL, or UL markings anywhere on the device. These are very important, so I’d advise against trying to use this in any certified (ISO / Government) environment.

The LED indicators work and the indicator guide is proofread and legible. The ends can rotate about, allowing you to get a better angle for usage. Not sure if it’s long-term waterproof, it’s an alright alternative for the price.

I got this to replace one that walked away at a camp site, and I think it's a little nicer than the one I had for about the same cost. I like the indicators and labeling, and it seems durable.

This surge protector does exactly what I wanted it to do. It’s very well made and seems pretty tough. If you need a surge protector this one is worth it.

I have seen equal surge protectors at camping stores for about twice the cost of this unit. These units show you any wiring or connection problems, but offer limited surge and over/under voltage protection. This unit seems well made and offers decent protection for the price.
