1. GenTent Generator Running Cover
Purpose-built weather canopy designed for generator operation with ventilation.
GenTent is designed to protect the generator’s electrical areas while preserving cooling airflow and exhaust clearance.
It is fundamentally different from a fitted storage cover, which should never remain on during operation.
Why It Stands Out
- Designed for operation
- Maintains airflow
- Weather protection
- Multiple sizes
- Portable
What to Consider
- Higher price
- Fit must be correct
- Not a CO solution
- Still requires safe outdoor placement
Best for: outdoor operation during rain or snow.
2. Champion Generator Storage Cover
Fitted storage cover for compatible Champion portable generators.
Champion’s fitted covers protect stored generators from dust and moisture when the engine is cool and not operating.
Model-size matching matters to avoid loose fabric and trapped moisture.
Why It Stands Out
- Brand-specific fit
- Weather resistant
- Easy to install
- Good dust protection
- Affordable
What to Consider
- Storage only
- Not for hot generator
- Fit varies
- Can trap moisture if stored wet
Best for: covered storage of compatible Champion units.
3. Westinghouse Generator Cover
Fitted cover for Westinghouse open-frame and inverter models.
Westinghouse offers size-specific covers for several generator families.
The main advantage is predictable fit around handles, frames and wheels.
Why It Stands Out
- Model matching
- Clean appearance
- Dust protection
- Outdoor-storage aid
- Simple use
What to Consider
- Not for operation
- Must cool first
- Different sizes required
- Not fully waterproof enclosure
Best for: Westinghouse generator storage.
4. Generac Portable Generator Cover
Heavy-duty fitted cover for selected Generac portable models.
Generac covers are designed around the frame dimensions of compatible portable generators.
They help preserve the finish and reduce debris accumulation between uses.
Why It Stands Out
- Brand fit
- Durable construction
- Good dust barrier
- Simple handling
- Recognized support
What to Consider
- Storage only
- Model-specific
- Can be costly
- Must avoid trapped moisture
Best for: Generac portable generator storage.
5. Universal Generator Storage Cover
Adjustable storage cover for common open-frame generator sizes.
A universal cover is the lowest-cost choice when exact model-specific fit is unavailable.
Measure length, width and height carefully and leave the generator fully cool and dry before covering.
Why It Stands Out
- Affordable
- Many sizes
- Easy replacement
- Broad compatibility
- Good dust protection
What to Consider
- Loose fit possible
- Storage only
- Quality varies
- Moisture management matters
Best for: basic indoor or sheltered storage.
How to Choose
Separate Running and Storage Covers
They are not interchangeable.
Preserve Ventilation
Never trap heat or exhaust.
Match the Generator Size
Measure frame, handles and wheels.
Let the Engine Cool
Storage covers go on only after cooling.
Avoid Trapped Moisture
Store dry and ventilated.
Keep Safe Placement
A running cover does not reduce CO distance rules.
