Why I Never Plug Into a Campsite Without This 30 Amp RV Surge Protector
Living full-time in an RV has taught me one thing: never gamble with your rig's electrical system. Here's how the Progressive Industries 30A Portable EMS has saved me more than once — and why I always travel with it.

My Go-To RV Surge Protector: Progressive Industries EMS-PT30X (30 Amp)
When I first hit the road in my RV, I didn’t think twice about power protection. I’d simply plug into whatever pedestal was available and hope for the best. That changed quickly after a fellow camper told me their story of a power surge frying half their electronics. The very next day, I invested in the Progressive Industries 30 Amp Portable EMS with Surge Protection (affiliate link) — and I haven’t looked back since.
Why I Chose This Unit
After some research, I wanted something:
Portable (I didn’t want to hardwire anything yet)
Reliable surge protection
Digital readout for real-time voltage monitoring
And ideally, a trusted brand with a good track record
This model checked all the boxes. The Progressive Industries EMS-PT30X (affiliate link) is rugged, weather-resistant, and easy to use — even if you're new to RV life.
What It’s Like Using It Day-to-Day
It’s super straightforward: I plug this unit into the power pedestal first, then plug my rig into the EMS unit. Within seconds, it runs diagnostics and tells me if there are any issues — like low voltage, open ground, or reversed polarity. A few times, it’s flagged low voltage that I would have otherwise missed. That saved my air conditioner and microwave from potential damage.
Even in pouring rain or snow, the weather shield keeps the unit protected. I also really like the locking bracket — I use a small cable lock to keep it secure at campsites.
⚡ Tip: Always plug this in before hooking up your RV. If something’s wrong with the power supply, you’ll know before any damage is done.
Peace of Mind in a Compact Package
One of the biggest surprises for me was how many parks have sketchy electrical setups. From loose wiring to sudden voltage drops during peak hours, you just never know what you’re getting. Having this 30A surge protector (affiliate link) between my RV and the pedestal gives me real peace of mind.
And yes, it’s a bit of an investment upfront — but replacing a fried RV refrigerator or converter would cost way more.
Final Thoughts
If you spend time in an RV — whether weekend camping or full-time — I highly recommend adding this to your must-have gear. It’s been a quiet workhorse for me, and I’d feel uneasy plugging in without it.
You can find it here on Amazon (affiliate link) — and trust me, it’s one of the smartest upgrades I’ve made since hitting the road.
