If I plan to use it around my home or while camping, I would place it at a safe distance and use it in a way that reduces disruption.
Outlets and Compatibility
One thing I always check is whether the generator has the right outlets for my needs. I like having multiple connection options because it gives me more flexibility. Before buying, I would make sure the outlet types match the appliances, transfer switch, or extension cords I plan to use.
