The Ultimate Buying Guide: Protecting Your Power Source

Generators are lifesavers when the power goes out. They keep your lights on and your fridge running. But to keep your generator working well, you need to protect it. A good running generator cover is essential. This guide helps you pick the best one.

Key Features to Look For

When shopping for a generator cover, look for these important things:

  • Weatherproof Design: The cover must keep rain, snow, and sun away. Look for strong seams that do not let water seep through.
  • Ventilation: This is very important! Generators create heat when they run. Good covers have vents so hot air can escape. If air cannot escape, your generator can overheat and break.
  • Easy Access Points: You need to reach the controls, oil dipstick, and fuel tank without taking the whole cover off every time. Look for zippered or Velcro flaps that open easily.
  • Secure Fit: The cover should fit your generator snugly. It should have strong straps or drawcords to keep it tight, even in strong winds.
  • Noise Reduction (Bonus): Some heavy-duty covers offer a little bit of sound dampening. This makes the generator a bit quieter when it runs.

Important Materials

The material determines how long the cover lasts and how well it protects your machine.

Heavy-Duty Fabrics
  • Polyester (600D or higher): This is a popular choice. Higher “D” numbers (like 600D) mean the fabric is thicker and stronger. It resists tears well.
  • Vinyl or PVC Backing: Many good covers have a waterproof layer glued to the inside of the fabric. This makes the cover truly waterproof.
  • Ripstop Nylon: This material has special threads woven in a grid pattern. If a small tear starts, these threads stop it from spreading further.

Factors That Improve or Reduce Quality

Not all covers are made the same. Quality really matters for long-term use.

What Makes a Cover Better?
  • Double Stitching: High-quality covers use double or triple stitching on all seams. This prevents weak points where water can enter.
  • UV Resistance: Sunlight breaks down fabric over time. A good cover will have UV-resistant coating so it does not become brittle and crack after one summer.
  • Sturdy Zippers: Look for heavy-duty zippers, often made of plastic or brass, that resist rust. Cheap zippers break quickly.
What Lowers the Quality?
  • Thin Plastic Sheeting: Avoid covers that feel like cheap plastic bags. They tear easily and offer poor heat resistance.
  • Poor Fit: If the cover is too loose, wind whips it around, causing wear and tear. If it is too tight, you cannot access necessary parts.

User Experience and Use Cases

How you use your generator affects the cover you need.

Camping and Portability

If you use a small, portable generator for camping, you need a lightweight cover. It should be easy to fold up and pack away when the generator is running or being moved. Access flaps must be quick to open.

Home Backup Power

If your generator sits outside your home for emergency backup, you need maximum protection. Look for a heavy-duty, fully enclosed cover that can handle extreme weather, like heavy snow loads or high winds. These covers often stay on the unit permanently.

Remember to always turn the generator off and let it cool down completely before putting the cover on. Covering a hot engine traps too much heat!


10 Frequently Asked Questions (FAQ) About Running Generator Covers

Q: Can I leave the cover on while the generator is running?

A: Yes, but only if the cover is specifically designed for running use. These covers have excellent ventilation built in. Never use a standard storage cover while running; it will cause overheating.

Q: How do I choose the right size?

A: Measure your generator’s length, width, and height (L x W x H). Buy a cover that is slightly larger than these dimensions to ensure a comfortable fit and easy installation.

Q: Will a cover stop rain from getting into the engine?

A: A good, weatherproof cover stops rain and snow from reaching the main housing, controls, and exhaust ports, keeping the sensitive parts dry.

Q: Are these covers waterproof or just water-resistant?

A: The best covers are fully waterproof due to their PVC or vinyl backing. Water-resistant materials will shed light rain but might soak through during a heavy storm.

Q: How often should I clean my generator cover?

A: Clean your cover at least twice a year. Use mild soap and water to gently scrub off dirt and mildew. Rinse well and let it air dry completely before storing or reinstalling.

Q: Do I need a cover if my generator is stored under a porch?

A: Yes. Even sheltered areas are exposed to dust, humidity, and UV rays from the side. A cover protects finishes and prevents dust from clogging air intakes.

Q: What is the purpose of the vents on a running cover?

A: The vents allow the heat produced by the running engine to escape safely. This prevents the engine from getting too hot, which protects the internal components.

Q: Can I use duct tape to fix a small tear?

A: Temporary fixes like duct tape work, but they usually fail quickly. For a long-lasting repair, use a specialized fabric repair patch kit made for outdoor gear.

Q: Will the cover protect against freezing temperatures?

A: It helps insulate slightly against wind chill, but a cover is not a heater. For extreme cold, you might need a specialized insulated blanket kit in addition to the cover.

Q: How should I store the cover when the generator is running?

A: If the cover is designed for running, simply open the access flaps and secure them neatly using the attached ties or Velcro straps. Do not wad the cover up near the hot exhaust.
