Campground power is a bit like campground Wi-Fi. Sometimes it’s great. Sometimes it’s “technically working,” but you’re one bad connection away from something expensive getting toasted.
A surge protector isn’t a “nice-to-have” in my world. It’s a basic layer of protection between your RV and whatever mystery wiring is sitting behind that pedestal.
Quick context: I personally use the Kohree 30 Amp RV Surge Protector. I like that it’s straightforward, easy to read, and doesn’t make setup feel like a science project.
The Kohree 30 Amp Surge Protector (10,000 Joules)
One thing that doesn’t get talked about enough with surge protectors is how often they’re exposed to bad environments, not just bad power.
Campgrounds aren’t clean electrical labs. They’re wet, dusty, humid, and sometimes downright sloppy. Between rainstorms, condensation, coastal humidity, and aging power pedestals, surge protectors live a rough life.
The Kohree 30 Amp unit is built for outdoor use, but like any portable surge protector, long-term exposure to moisture still matters.
This is protection gear, not magic. Environment always plays a role.
The headline feature here is the protection rating: 10,000 joules. In plain English, that’s how much electrical abuse the unit can absorb before it gives up.
- 30 amp RV fit: for rigs wired for 30A service.
- 10,000 joules: strong surge absorption capacity.
- LED readout: see voltage conditions instantly.
- Weather-resistant housing: designed for campground use.
Chart 1: 30 Amp vs 50 Amp Surge Protectors
This is the part most people overthink. Match the surge protector to your RV’s service, then stop stressing.
| Feature | 30 Amp | 50 Amp |
|---|---|---|
| Power Capacity | 3,600 watts | 12,000 watts |
| Suitable RV Size | Smaller / mid-sized RVs | Larger RVs |
| Protection Level | High | Higher |
| Cost | Affordable | Pricier |
| Weight | Lightweight | Heavier |
Chart 2: Pros and Cons of the Kohree 30 Amp Surge Protector
| Pros | Cons |
|---|---|
| Reliable surge protection | Can be bulky |
| Clear LED diagnostics | Occasional false readings |
| Weather-resistant design | Not for 50A rigs |
| Portable | No Bluetooth features |
| Affordable | Requires care in heavy rain |
UPDATE: Costa Rica Rainy Season Reality
When we arrived in Costa Rica last year, we hit the rainy season hard. The Kohree surge protector stayed plugged in through sustained rain, high humidity, and constant moisture in the air.
Over time, despite the seals doing most of their job, moisture still made its way inside the unit. Eventually, it shorted out and became inoperable.
And here’s the important part: I still recommend it.
It failed so my RV didn’t have to. I’ll replace a surge protector long before I replace appliances, wiring, or an inverter.
I miss it. For wet climates, add shelter or unplug during extreme weather.
Quick Setup Notes
- Turn pedestal power off first.
- Plug surge protector into pedestal.
- Connect RV cord.
- Turn power back on and check display.

I enjoyed this review, even if I hardly understand what’s the product is! RV that are LED-equipped are more eco-friendly, though they are difficult to read. But seriously, I really like the fact that it’s also user-friendly, so that even people like me who are newbies can use it quite instinctively. It’s very important for us to have the best RV for our daily lives.

Hey angelce903! Thanks for your comment—glad you enjoyed the review! I totally get it; surge protectors aren’t always the easiest thing to wrap your head around at first. But I’ll break it down for you a bit more!
The 30 Amp RV surge protector is basically a device that protects your RV’s electrical system from power surges and spikes, especially when you’re hooked up to campground power. These power fluctuations can damage your RV’s appliances, so the surge protector acts as a safety buffer, keeping everything running smoothly and avoiding costly repairs.
As for the user-friendly aspect, you’re spot on! Many of these devices, like the one I reviewed, are designed for folks who aren’t electricians or tech experts, so they’re easy to use right out of the box. Just plug it into the power pedestal, connect your RV, and you’re good to go. It’s great peace of mind for newbies and seasoned RVers alike!
And yeah, LED-equipped RVs can be more eco-friendly because they use less power, but you can still benefit from a surge protector whether your rig is LED-heavy or not. It’s all about protecting your investment and keeping things safe on the road.
Hope that clears things up a bit! Let me know if you have any more questions.
Cheers,
Jeremy

Surge protectors often save heartache and regret. The one you’ve reviewed here for RVs definitely fits the bill. Looking at the rest of your website articles, particularly the ones on off-the-grid options, look particularly intriguing. I’ve got a shed out back of my home that I am considering using a stand-free power option – any suggestions?

Hey Elridge!
Thanks for the comment, and you’re absolutely right—surge protectors really do save a ton of heartache! Glad the review resonated with you.
As for going off-grid with your shed, that sounds like an awesome project! If you’re looking for stand-alone power options, solar panels are a great choice, especially paired with a battery bank to store energy. There are also some compact wind turbines that might work depending on your location. Another option to look into is a portable generator, particularly one that’s dual-fuel, so you’ve got some flexibility between propane and gas.
I’ve written a bit about off-grid power setups on the site, so feel free to explore those articles for more detailed info. Let me know if you have any questions as you get your project going—I’d love to hear how it turns out!
Cheers,
Jeremy
