What's the best generator cover? If you just spent big bucks on a generator, you'll want to make sure you store it properly. A cover keeps dirt, leaves and other debris from damaging the generator.

To find the best options, we surveyed our readers who live in hurricane country for their picks. We took these suggestions and did additional research, comparing durability and performance. Here are the ones we'd recommend.

FYI: We've been reviewing and rating products for the home and families since 1994. To keep our work independent, we don't take money or freebies from the brands we review. Our work is 100% reader-supported. Thanks for reading!

Best Small Generator Cover

Best Small Generator Cover: Porch Shield Waterproof Universal Generator Cover

Yes, generators can be pricey investments—a good one can easily run into the four figures! One thing you quickly learn about owning a generator is that storing it properly is important, so it is ready for that next emergency. A good generator cover should be part of your storage routine. Generators are basically engines . . . and dust, dirt and debris can cause damage. For the best small generator cover, we recommend Porch Shield’s Waterproof Universal Generator Cover. Here’s why:

What We Liked

• Sturdy, 600D polyester fabric.

• Elastic hem cord secures this cover to the generator.

• Water resistant laminated undercoating.

• 3 sizes available. The one recommended in this article is for smaller generators (32″ x 24″ x 24″). That is usually in the 5000 to 10,000 watt range.

• Sealed seams.

• Velcro closure on one end.

What Needs Work

• UV light (from sunlight) can cause fading and cracking after time.

• Not the best choice for windy areas. If you store your generator outside and live in a windy area, this may not be the best choice. We see reports online that some folks had issues with high wind and this cover.

Best For Champion Generators

Fits like a glove
We liked how this cover is designed to fit over the generator's wheels, letting you move the unit around while still keeping it covered. Lined with cotton to keep generator from being scratched.

Best For Champion Generators: Champion Weather Resistant Storage Cover for 4800-11,500 Watt Portable Generators

Champion is an excellent generator brand that we’ve recommended in our other articles. If you have a Champion generator and want a cover designed to fit it like a glove, we’d recommend the company’s own covers. And surprisingly, they are competitively priced. Here’s more:

What We Liked

• Easy to use.

• Excellent fit.

• Elastic base to keep it place.

• Covers the generator but leaves the wheels exposed—that enables you to move the generator around while covered.

• Affordable.

What Needs Work

• Not designed for other generator brands. So the fit will be hit or miss if you try this on a non-Champion generator.

• Long-term durability could be better. We see a few reports that it cracked or fell apart after long-term use.
