Are you trying to find the best portable generator covers?

If you’re a full-time RVer or enjoy camping off the grid, one of the most important investments you can make is in a portable generator. A portable generator can get you out of a ton of jams and help you make memories that otherwise wouldn’t be possible. If you’re going to invest in a portable generator, however, it’s crucial that you protect your investment. 

One of the best ways to do this is with a portable generator cover. There are many different types of portable generator covers including those specifically for storage and those that you can use while your generator is running. For maximum protection, it might be worth your while to invest in one of each. 

If you recently purchased a portable generator to add to your RV and want to protect it, you’ve come to the right place. Portable generator covers can protect your generator from elements such as rain, snow, and debris during storms. It’s important that you have the right cover for your generator and that you specifically choose a running cover if you want to cover your generator while it’s running. 

How to Choose the Best Portable Generator Cover

Type of Cover

The first major thing to consider when picking the best cover for your portable generator is the type of cover you want. In general, the two types of covers are ones for storage and ones for protection that you can use while the generator is running. The latter type of cover won’t be airtight and will leave openings around the generator near the intake and exhaust for airflow. 

Both types of covers will work for most generators, but the times when you use them will differ. 


The material your cover is made of is the next most important thing to consider. In order to be effective, the cover should be made of waterproof material that’s flexible, compact, and easy to store. You also want it to be durable so that it doesn’t rip or tear when it’s subjected to storms, winds, and debris.

Most waterproof canvas covers will be made of some type of polyester, vinyl, nylon, or tarpaulin. 


Durability and the quality of the material your cover uses are tied hand in hand with one another. In order for a portable generator cover to be effective, it has to be waterproof and tearproof. If it checks both of these boxes, it will likely be durable as well. 


You’ll probably be surprised to learn that there’s a big price range when it comes to portable generator covers. In general, running covers are much more expensive than storage covers because they have more capabilities and more intricate designs. However, if you want to use your generator while it’s covered, you’ll have to cough up the money for a running cover. 

Ease of Use

The main goal of a generator cover is to provide protection for your generator. While it’s worth paying whatever is necessary to make this happen, certain covers are much easier to use than others. You might have to get your cover out and erected in a hurry, which means you’ll need a cover that’s easy to use. Easy covers might cost a little more, but it’s well worth it when you’re in a hurry.

Champion Storm Shield

Champion Storm Shield Severe Weather Portable Generator Cover by GenTent® for 3000 to 10,000-Watt Generators

"I bought a 7500 watt Champion generator and in two months time, I have used it 3 times. I felt very uncomfortable using the generator uncovered. I put off buying this cover but after second outage, decided to buy it. Its a 5 minute install. No tools needed. I do not know about its claim to withstand 70 MPH winds, but I can tell you it held up to 45 MPH winds with ease. Its a bit pricey for what it is.. But not so much for what it does. Protect your investment and buy one. It looks great just as picture shows." - Frederick N.
