Portable Generators for Motorhome Camping – Your Power Guide

When you hit the road in a motorhome, the last thing you want is a dead battery or a cold shower. A portable generator can be the difference between a comfortable night and a frustrating one. Below you’ll get the basics on picking a generator, how to run it safely, and a few tricks to stretch the power you have.

Choosing the Right Generator

First, think about what you actually need to run. A small fridge, a 12‑volt TV, lights and a phone charger usually need less than 1,500 watts. If you plan to heat water or run a big air‑conditioner, look for 2,000 watts or more. Most campers settle on a 1‑2 kW inverter‑style generator because it’s light enough to store in a van and quiet enough for neighbours.

Fuel type is another big factor. Gasoline is easy to find, but it can go stale if you store it for months. Propane burns cleaner and lasts longer, but you’ll need a refill tank. Some models let you switch between gasoline and propane, giving flexibility on long trips.

Noise matters if you’re staying at a campsite with thin walls or pitching a tarp near other campers. Look for generators rated under 60 dB – that’s about the sound of a normal conversation. Many newer units have “eco‑mode” that ramps down the engine when the load is light, keeping the hum low.

Using Your Generator Safely on the Road

Place the generator on a flat surface and keep it at least two meters away from your vehicle or any flammable items. Never run it inside a motorhome, even with the windows open – carbon monoxide can build up fast.

If you’re boondocking (free‑camping off‑grid), you’ll often rely on a 12‑volt system. Connect the generator to a power inverter that matches your battery’s voltage. This lets you run a TV, charge phones, or power a small fridge without converting everything to 120 V first.

Keep an eye on fuel levels and the exhaust temperature. Most generators have a low‑oil shut‑off; if that trips, let the engine cool, add oil, and restart. A quick check of the spark plug after each long run can prevent misfires later.

When you’re done for the day, let the generator idle for a minute before you shut it off. That reduces strain on the engine and helps the fuel system settle.

Finally, think about storage. Drain the fuel if you’ll be away for more than a month, or add a fuel stabiliser. Wipe down the exterior, cover it with a breathable tarp, and store it in a dry locker inside the motorhome if possible. A clean generator lasts longer and starts easier.

With the right generator and a few safe‑use habits, you’ll have power for cooking, charging devices, and staying warm – no matter where the road takes you.
