Introduction

When it comes to RV living, power is everything — from morning coffee to keeping your batteries charged overnight.

But without the right accessories, even the best electrical system can leave you powerless (and frustrated).

This guide highlights the must-have RV power gear — tools that protect your rig, extend your reach, and make powering your adventures safe and simple.

⚡ 1. RV Surge Protector: Your First Line of Defense

Think of a surge protector as insurance for your RV’s electrical system.

What It Does:

• Protects against voltage spikes and faulty campground power.
• Monitors for open ground, reverse polarity, and low voltage.
• Shuts down automatically during dangerous surges.

💬 Pro Tip: Always plug your surge protector into the pedestal before connecting your RV cord.

Recommended: Progressive Industries EMS or Camco Power Defender.

🔌 2. Heavy-Duty Power Cords and Extension Cables

Your RV needs the right gauge cord to handle the amps safely.

Power Cord Types:

• 30-Amp Cord: Standard for small RVs and travel trailers.
• 50-Amp Cord: For larger rigs and motorhomes.

Tips:

• Use outdoor-rated, heavy-duty cords only.
• Keep connectors clean and dry.
• Avoid coiling cords tightly — it traps heat.

💬 Budget Tip: Carry a short 10-foot and a long 25-foot cord for maximum flexibility.

🔄 3. Dogbone Adapters (Power Plug Adapters)

Sometimes, the campground power pedestal doesn’t match your rig — that’s where dogbone adapters come in.

Examples:

• 30A RV → 15A household plug
• 50A RV → 30A pedestal
• 15A plug → 30A RV

💬 Pro Tip: Use only for temporary power — adapters can limit current flow and overheat under heavy loads.
