Shore Power for Camper Vans: How It Works and What You Need
By Frank Zale · August 1, 2026 · 3 min read
Shore power is the campground trick that lets you plug your van into a wall and run everything without touching your battery. Set up right, it charges your house bank, powers your AC appliances, and gives your solar a rest — all from a standard outlet. Here's how it works and the parts you need.
What "shore power" means
Borrowed from boating, shore power just means connecting your van to an external AC source — a campground pedestal, a garage outlet, or a friend's driveway. While plugged in, your van runs on grid power instead of your battery, and a charger tops the battery back up.
What you can do while plugged in
- Charge your house battery fully (great after cloudy stretches)
- Run AC appliances — heater, kettle, tools — without draining anything
- Rest your solar and battery, extending their life
It's the perfect complement to solar and alternator charging: three input sources means you're never stuck without power.
The parts you need
| Part | Job |
|---|---|
| Shore power inlet | A weatherproof socket on the van's exterior you plug the extension cord into |
| Extension cord | Heavy-gauge cord from the pedestal/outlet to the inlet |
| AC distribution / breaker | A small breaker panel or RCD for safety on the AC side |
| Battery charger or inverter/charger | Converts incoming AC back into DC to charge your battery |
The smart choice: an inverter/charger combo
Instead of a separate inverter and a separate charger, many builders use one inverter/charger unit. It does both:
- Unplugged: works as a normal inverter, turning battery power into AC.
- Plugged in: flips to charger mode, powering your AC outlets from shore power and charging your battery at the same time — often with automatic pass-through so it switches seamlessly.
It costs more up front but saves space and wiring versus buying two devices, and it's the cleanest way to add shore power to a build.
Safety essentials
AC power is more dangerous than 12V DC — treat it with respect:
- Use a proper shore power inlet, not a bare cord dangling out a window
- Include an RCD/GFCI breaker on the AC side to cut power on a fault
- Use correctly rated cable and connectors
- Keep AC and DC wiring physically separated in the van
If you're not confident with AC wiring, this is the part of the build worth having checked by an electrician. The pre-purchase checklist covers where professional help pays off.
Do you even need shore power?
Honest answer: it's optional. Plenty of full-time vanlifers run solar + alternator only and never plug in. Add shore power if you:
- Regularly stay at campgrounds with hookups
- Park at a home base with a garage outlet
- Run power-hungry AC appliances and want to top up fast in winter
If you rarely see an outlet, spend that money on more battery or solar instead. Model the tradeoff with the free calculator.
FAQ
What is shore power for a camper van?
It's connecting your van to an external AC outlet (campground pedestal, garage plug) so you can run appliances and charge your battery from the grid instead of your battery.
Do I need shore power if I have solar?
No — many vans run on solar and alternator charging alone. Shore power is a convenient bonus if you stay at hookup campgrounds or have a home base with an outlet.
What's the difference between an inverter and an inverter/charger?
An inverter only turns battery DC into AC. An inverter/charger also runs in reverse — when you plug into shore power it charges your battery and powers your outlets at once.
Is a shore power hookup safe to install myself?
The DC side is beginner-friendly, but the AC side carries real shock and fire risk. Use a proper inlet and an RCD/GFCI breaker, and have the AC wiring checked if you're unsure.
