Quick answer: the beginner map of RV power
Most RVs use some combination of:
- Shore power (plugging into a campground pedestal) for the easiest, highest-capacity power.
- Batteries to run 12V essentials like lights and the water pump.
- An inverter (sometimes) to turn battery power into 120V power for certain outlets and appliances.
- Solar to recharge the batteries in daylight.
- A generator for big loads off-grid (often air conditioning) and faster battery charging.
Your best setup depends on what you want to run (A/C, microwave, coffee maker, CPAP, laptops) and where you camp (full hookups, partial hookups, or boondocking).
Step 1: Make a simple “what we want to run” list
Before you compare equipment packages, write down two lists:
1) Must-run items (things that make the trip possible)
- CPAP
- Medical devices
- Phone charging
- Fridge operation (this depends on RV type)
2) Nice-to-have items (comfort and convenience)
- Microwave
- Hair dryer
- Electric kettle
- Air conditioner
- Streaming and gaming
This list prevents the most common mistake beginners make: buying a power setup that is impressive on paper but does not match how you will actually camp.
Shore power in plain English (30 amp vs 50 amp)
Shore power is what you get when you plug the RV into a campground or RV-park electrical pedestal.
What 30 amp usually means
- Common on many travel trailers and smaller RVs.
- Enough for normal camping routines, but you may need to manage loads (for example, microwave plus A/C plus space heater can be too much at once).
What 50 amp usually means
- More available power and usually more flexibility to run multiple high-draw appliances.
- Common on larger fifth wheels and some larger travel trailers and motorhomes.
Practical shopping tip
Do not treat 50 amp as “better” for everyone. Treat it as “more capacity.” If you mostly camp with hookups and do not run heavy loads simultaneously, a 30 amp RV can be a great fit.
Real-world add-ons to plan for
Even if your RV has the right service, most owners end up wanting a few basics:
- Adapters (because pedestals vary)
- A quality surge protector (helpful protection from bad power)
- A plan for cord length and storage (how far the pedestal is from the RV matters)
Batteries, 12V vs 120V, and the inverter misunderstanding
Here is the core concept:
- 12V power runs many RV essentials: lights, fans, water pump, control boards, some USB outlets.
- 120V power runs household-style outlets and high-draw appliances: microwave, toaster, hair dryer, many TVs, and often air conditioning.
The converter/charger (the quiet workhorse)
When you are on shore power, your RV uses a converter/charger to:
- Supply 12V power for the RV systems
- Recharge your battery
If you plan to camp on hookups often, a solid charging setup matters because it keeps the batteries healthy and ready.
The inverter (what it does, and what it does not)
An inverter can take battery power and provide 120V power for some outlets.
Two important beginner notes:
- Not all RVs have an inverter.
- Even if an RV has an inverter, not all outlets are always powered by it. Some rigs power only a few “inverter outlets.”
If you are shopping because you want to run a coffee maker in the morning without a generator, ask:
- “Which outlets are on the inverter?”
- “What size inverter is installed?”
- “Can it run the appliance we care about?”
Lithium vs lead-acid batteries (why it changes your day)
You will hear a lot about lithium batteries. The helpful, practical version is:
- Lithium can offer more usable capacity and faster charging, but at a higher cost.
- Lead-acid (including AGM) is common and proven, but you typically use less of the rated capacity if you want long life.
You do not need to chase the “best” battery. You want the right amount of usable power for your routine.
Solar: panels, controller, and storage (the three-part system)
Solar is often talked about as if it is one feature. In reality it is a system:
1) Panels collect energy
2) A charge controller manages charging
3) Batteries store the energy
Solar can be a great way to reduce generator time, keep batteries topped off, and make off-grid camping calmer.
The most important solar question
Not “how many watts of panels,” but:
“How much energy do we use per day, and can we reliably replace it?”
Your answer depends on:
- How long you camp off-grid
- Whether you camp in shade, in winter, or in coastal fog
- What loads you use (laptops and lights are different from electric cooking)
Solar shopping checklist (quick version)
When you tour units, look for:
- Roof pre-wiring or “solar ready” design
- Where the controller is located (easy to access is nice)
- Battery compartment size (future upgrades need space)
- Clean cable routing (expansion is easier when the basics are done well)
Generators: when they make sense (and what to ask)
A generator is usually about one thing: high-demand loads off-grid.
Common reasons people want a generator:
- Running air conditioning when there are no hookups
- Powering the microwave or other high-draw appliances off-grid
- Charging batteries quickly
Built-in vs portable
- Built-in generator: convenient, typically integrated, but part of the RV and its maintenance.
- Portable generator: flexible and can be carried in a truck bed or storage area (when safe), but you manage setup, fuel, and security.
A/C is the generator stress test
Air conditioners can have a high startup draw. If you want to run A/C off-grid, ask about:
- Generator capacity for that specific RV
- Whether the A/C has a soft-start installed or can be added
Noise and campground rules
Generator use is often restricted by campground quiet hours and policies. If you are not sure, plan to check campground rules for where you like to stay.
Three “power profiles” that keep you from overspending
If you are not sure where you fit, choose the closest profile and build from there.
1) The full hookups traveler
Best priorities:
- Shore power convenience
- Surge protection
- Practical cord management
You may not need heavy solar or a large inverter if you rarely camp without plugging in.
2) The weekend boondocker
Best priorities:
- Battery capacity that supports your basics
- An inverter for a few convenience items (if desired)
- Solar that can refill what you use each day (when sun is available)
This is where many people get good value from “solar ready” setups and sensible battery upgrades.
3) The remote worker (or always-on comfort person)
Best priorities:
- A realistic plan for all-day device charging
- Inverter capacity and outlet coverage that matches your devices
- Redundancy (two ways to recharge: shore, solar, generator)
Focus on reliability first.
On-the-lot checklist: what to look at in five minutes
When you are walking an RV at Oregon RV Outlet, here are easy things to spot and photograph:
- The power cord and where it stores
- The converter/charger location (ask if you cannot find it)
- Battery compartment size and accessibility
- Whether the RV has an inverter (and which outlets it powers)
- Any solar controller screen or panel label
- Generator presence (built-in) or generator storage options (portable)
If you take a few photos of electrical labels and components, we can usually help you interpret what you are looking at without guesswork.
Southern Oregon and PNW considerations
- Coastal fog and shade: solar can underperform when you camp under trees or in cloudy coastal conditions, so plan a backup recharge method.
- Wet-season camping: moisture management matters. Fans, venting, and keeping interior humidity down protects comfort and finishes.
- Mountain grades on I-5 and regional highways: if you travel with a generator and extra fuel, plan secure storage and safe handling.
- Smoke season some years: running fans and charging devices indoors becomes more common, so battery capacity can matter more than you expect.
