Rain is drumming against the metal frame of your unit while the power stays on inside. You shouldn't have to choose between keeping the lights active and protecting your gear from a storm.
A running cover acts like a sturdy raincoat for your machinery, shielding delicate electronics from moisture while letting the engine breathe. Finding the Best Generator Cover While Runnings requires balancing airflow with heavy duty weather protection. Let's compare the top designs that keep your power source safe until the clouds clear.
Key Takeaways
- Prioritize 600D Oxford fabric to ensure the cover can withstand high winds and heavy precipitation without tearing.
- Verify that your chosen model includes dedicated side and top access panels so you can refuel and monitor gauges without exposing the entire unit.
- Match the cover dimensions to your generator frame specifically rather than relying solely on the advertised wattage range.
- Look for reinforced zippers and buckled straps because these components take the most mechanical stress during operation.
- Choose a design with flame retardant properties or heat resistant liners to prevent the material from melting near hot exhaust zones.

Frequently Asked Questions
Can I use a standard plastic tarp instead of a specialized cover?
Using a standard tarp is risky because it lacks the necessary ventilation to prevent carbon monoxide buildup. A tarp will trap exhaust gases and moisture, which can lead to engine failure or dangerous gas accumulation. Always use a purpose-built cover designed for safe operation while the generator is under a load.
Will a running cover protect my generator from snow?
Yes, these covers are excellent at keeping snow and ice out of the delicate intake vents. By preventing frozen buildup, you ensure the generator starts reliably during a winter power outage. Just make sure the ventilation ports remain clear so the unit does not ingest its own exhaust.
How do I know if a cover is compatible with my model?
Most manufacturers offer covers specifically sized for their generator wattage or series. If you cannot find a model-specific cover, search for one that matches your generator's physical dimensions within an inch or two. A slightly larger cover is usually manageable if it includes adjustable straps to secure the fabric.
Do these covers add significant weight to my generator?
Not really, as they are typically made from lightweight, durable synthetic fabrics. You might add a few pounds at most, which is negligible compared to the weight of the generator itself. The benefit of corrosion protection far outweighs the minor increase in total weight.
Should I remove the cover if the wind gets too strong?
If the wind is severe enough to lift the generator or cause the cover to vibrate aggressively, you should remove it. High winds can turn a loose cover into a potential projectile or cause it to tear away from the frame. It is better to have a slightly wet generator than a shredded cover wrapped around your cooling fan.
