We’ve talked a lot about solar power on this blog over the years, and we’re big fans. We’ve got what for us is the ultimate RV solar panel system, and it has served us very well overall. But there’s no getting around the fact that the sun goes down every night, and that clouds, rain, trees, and other things that interfere with the sun happen regularly. We recently read about an innovative portable RV wind turbine, and it got us thinking – would a wind turbine be a good choice for RVers and campers?

What Is an RV Wind Turbine?
An RV wind turbine is essentially a portable windmill that uses the power of the wind to generate electricity to power your RV’s devices and appliances when you’re off-grid.
An RV wind turbine is usually mounted on the roof of the RV, mounted to the RV ladder, or sometimes on a pole that stands independent of the rig (using either a hitch-mounted flag pole holder or one you can park the RV’s tire on).
A wind turbine does the opposite of what a fan does. A fan uses electricity to create wind, while a wind turbine uses wind to create electricity.
Let’s take a closer look…
How Does an RV Wind Turbine Work?
A wind turbine has large blades that turn by the power of the wind. As the blades spin, the aerodynamic force of the rotor blades turns the generator, creating electricity. The faster the rotor blades spin, the more electricity is generated.
RV wind turbines are usually capable of generating no more than a few hundred watts at 12V or 24V.
Is a Wind Turbine Capable of Powering an RV?
In theory, a wind turbine can power an RV. But in real-world practice, it’s not quite as smooth a process as one might think, simply because the amount of electricity generated by a wind turbine that’s small enough to be easily portable isn’t all that much… and is very much dependent on the weather. Depending on how much power you need to generate, and how cooperative the weather is, you could easily find yourself short on power.
The cool thing is that though the sun goes down at night, and thus doesn’t generate solar power, wind can continue through the night. This means a wind turbine can continue to generate electricity.
But because wind turbines only generate power when the wind is blowing, it’s important to connect an RV wind turbine to a battery bank to store that energy for later use. Some RV wind turbines plug directly into an RV house battery bank, however, it’s more efficient to connect the turbine to a charge controller just as we do with solar panels. This not only increases efficiency but also protects the battery bank. Many RV wind turbine systems include a charge controller for this reason.
Can I Use a Wind Turbine and a Solar Panel System Together?
Some (but not all) wind turbines can be combined with a solar power system, and there are combination kits available on the market that do exactly that. These are generally referred to as hybrid systems.
What’s the Downside of RV Wind Turbines?
There are some disadvantages to RV wind turbines, especially when compared with solar power systems.
The Right Amount of Steady Wind is Required
The greatest disadvantage of RV wind turbines is that a wind turbine generates no power at all unless the wind is blowing. And we’re not talking about a slight breeze here. Wind turbines typically require winds blowing at greater than 20 mph for maximum output.
However, it can be hard to enjoy camping in strong winds. Also, when using an RV wind turbine, you need to make sure there are no trees or other obstructions blocking the wind (though that’s less of a problem than trees blocking the sun for solar).
It’s also critical that the wind is blowing at just the right speed, and consistently so. And that’s something outside your control. But large gusts of wind not only aren’t helpful but can also shut the wind turbine system down (or, in the worst-case scenario, actually knock the system down).
So, generally speaking, RV wind turbines, while they’re capable of generating power with winds at around 10 mph, they require continuous winds of approximately 26-30 mph to generate electricity at their maximum rated capacity.
And, unlike the sun which we know will rise every morning and will be present at least to some degree daily, the wind is far less predictable.
Tall Items (Like Wind Turbines On Poles) Can Be Lightning Rods
Wind turbines work best when situated high in the air, with no obstructions nearby to block the wind. Unfortunately, this essentially makes them a lightning rod near or above your RV. Tall pointy objects are the subject of most lightning strikes, as noted in our post “How Safe is an RV in a Lightning Storm?”… so having a wind turbine mounted on a pole nearby your RV is increasing this risk.
Less Productive and Efficient Than Other Options
RV wind turbines are relatively inefficient, especially when compared with other off-grid power options like solar. This is because even given optimal wind speeds, a wind turbine produces less energy and is highly unlikely to fully power the devices and appliances in your RV.
Another problem is that wind turbines require a minimum wind speed, known as the “cut-in speed”, to generate any power at all. If the wind doesn’t reach the cut-in speed, no power is generated.
They also have a “cut-out speed” which is the fastest wind speed a given turbine can handle. Winds that blow faster than this speed risk damaging the wind turbine, and they also generate no additional electricity.
So, all in all, wind turbines require a very specific balance to achieve their maximum output, and even that is unlikely to adequately power your RV.
Need to Be Set Up and Dismantled for Travel
Another disadvantage of RV wind turbines is that every time you move to a new location – or move your rig at all – the wind turbine needs to be lowered or dismantled, and then set up again once you reach your next destination.
May Be Noisy
Some wind turbines can be quite noisy. The noise they make is often described as “whooshing” and/or “clicking”. If they’re mounted directly to your RV, they can also create vibrations that you’ll feel inside, which can be annoying to some.
Are There Upsides To RV Wind Turbines?
With all of the above said about the cons to using wind to provide power for your RV, there are some upsides. Especially if you’re considering using one as an additional source of power above and beyond your other options (solar or generator). Or, if you have minimal power needs (recharging small portable electronics) and tend to camp in shady areas (bad for solar) with steady winds.
We don’t think wind power is ready to be considered as a complete solution for off-grid power generation, but it does provide an interesting option for augmenting your power needs in certain situations.
Are There Small Portable Wind Turbines for Campers?
There are portable wind turbines on the market. There are even some hybrid kits that combine wind and solar power.
Unfortunately, the units we’ve looked at get very mixed reviews. Let’s take a look at a few:

As always, investigate and read reviews.
We recently read about one intriguing product in the Indiegogo space. It’s a portable wind turbine the size of a one-liter bottle, invented by Aurea, a Canadian company. Cat Adalay, a mechanical engineer, and Rachel Carr, a designer, invented the product known as the “Shine Turbine”.
The Shine Turbine is wind power that fits in a backpack. Yes, the entire package, including the tripod on which it’s raised, fits in a backpack.
The intent behind the Shine Turbine is to generate power for handheld electronics such as cell phones, tablets, cameras, etc. According to Aurea, in peak conditions, (there’s that little problem again), the Shine Turbine can generate sufficient power to charge a cell phone in 20 minutes.
It weighs three pounds, sets up in two minutes, and has a 12,000 mAh internal battery.
This is a great little product for campers, or so it would seem, and we wish them the best with the product which, in addition to generating power for small devices, has also generated a lot of attention.
To see videos of the Shine Turbine at work, check out their Indiegogo page dedicated to this product.
Is an RV Wind Turbine a Good Choice for RVers and Campers?
Wind turbines are certainly environmentally friendly and are capable of generating power all day and all night, given the right weather circumstances. However, those circumstances also mean that you’ll have to camp in windy conditions…and fairly precise ones at that.
If you need to power an entire RV or a number of more power-hungry devices and appliances, it would likely prove to be challenging at best, and you’d do well to invest your money in a solar system, portable generator, or solar generator, instead.
However, if you want to power/recharge a few smaller devices, or if you want to have some backup power in case the sun doesn’t provide enough charging from your solar array, a wind turbine could be a fun way to generate some additional power.
