When you’re rolling into a campground or plugging into shore power at an RV park, there’s one thing you shouldn’t gamble on — your RV’s electrical system. Whether you’re a weekend warrior or a full-timer, understanding your RV’s power system and how to protect it can save you from costly damage and frustrating outages.
Let’s break it down for beginners: what you need to know about RV power and why surge protection is non-negotiable.
What Is RV Power, Anyway?
Your RV runs on two primary power sources:
- 12-volt DC power (from batteries) — powers lights, water pumps, and fans.
- 120-volt AC power (from shore power or generator) — powers your air conditioner, microwave, outlets, etc.
When you plug into an RV park pedestal, you’re using their AC shore power, and that’s where things can get dicey if the power isn’t clean or reliable.
The Danger of Dirty Power
Not all RV parks are created equal. Some have aging electrical systems, improper wiring, or unstable voltage. These issues can cause:
- Power surges or spikes
- Low voltage (brownouts)
- Miswired pedestals
These problems aren’t just inconvenient — they can fry your air conditioner, refrigerator, microwave, and other pricey electronics in seconds.
Why You Need a Surge Protector (Seriously)
An RV surge protector acts like a bodyguard for your rig. It monitors incoming electricity and shuts things down if something isn’t right. Key benefits:
- Protection from spikes and surges
- Detection of miswired pedestals
- Low/high voltage protection
- Peace of mind (especially in sketchy campgrounds)
Smart Surge Protectors: Worth the Upgrade?
Yes, and here’s why: Many surge protectors now come with Bluetooth monitoring, letting you check voltage, amperage, and power status on your phone. Some even send alerts if things go south.

What Size Do You Need?
Surge protectors come in:
- 30 Amp – for smaller rigs and travel trailers
- 50 Amp – for larger RVs and fifth wheels
Match your protector to your rig’s power setup — and never force a 50-amp rig into a 30-amp pedestal without the right adapters and protection.
